New QRP RADIO: X1M QRP SSB/CW Transceiver $299

http://www.wouxun.us/item.php?item_id=302&category_id=65

I saw this selling on Ebay for $350 now as well as $299 at the Wouxun website. This is a 5 watt SSB/CW radio that promises all the ham bands however it lists only 5 bands with something about 'configured separately with additional filtering'.

(I did a search here on eham for X1M QRP Transceiver and yielded no results, so I guess this radio has not been mentioned yet.) This is an fully assembled radio according to the site.

The website says they are talking orders and it will be shipping in early May, but some Ebay seller from North Carolina has it now for $350.  The price seems great and for the price of a Youkits 4 band CW only rig, this radio appears to offer even more. Seems Wouxun is going to be importing these in to sell in the U.S.. The manufacturer seems to be  "Xiegu Technology"

The site goes on to mention that Wouxun.us is now "Import Communications" and that they will be at the Dayton Hamfest North Hall 175-176.  I have no connections to these guys whatsoever and just passing on the information that I found.

Yep, just looking for a QRP rig for a friend and come across this interesting little snippet. Interesting I say to myself, till I see that they want $500 U.S. dollars to send it to me. Now where I am that equates to NZ$592.85. Hmmm I say to myself, maybe they give me a discount if I chartered the 747 to bring it to me. I think I will pass on this and wait till my wife and I go to China, (pretty soon I might say) and I am sure I will get one for just a little less. Honestly the world is getting smaller but the price to move small articles is just prohibitive.

Cheers de zl3bj  ;D

I just ordered one from Import Communications in N. Carolina last week. According to Ed there, I should have it in a week or two. I have had email correspondence with a ham I Malaysia that I found a link to QRZ.com. He told me he has had one since last year and he loves it. There is another place supposedly selling it, Kight Radio. They do not return emails and have a non working phone number. I will report on the unit when I get it.

That's their way of saying they only want to sell it to a handful of countries.  I'm not sure why New Zealand wouldn't be in the list; it's not that hard to ship stuff there . It just takes a little while to arrive.

I live in Canada and while most US vendors will sell here, some ship by carriers with high customs clearance charges and some simply won't ship here.  I respond by partaking of other companies.

Hopefully a New Zealand-friendly source for this radio will come soon.

Produce a 25  watt PA  and LIPO battery pack for  the whole combination and you will have a winner. If  you also have a  MANPACK frame that includes the radio, amp and tuner you will  have winner.

If you wanted to take the radio to the next level. You can make a ready to go HF station by combining  2 X 25 watt PA's, antenna tuner, DC to DC converter 10 to 50 volts, AC power pack 90 to 260 volts as  portable radio setup.
50 watts is enough for portable/maritime/holiday/pedestrian mobile and casual operation. Pedestrian mobile is becoming very popular. The ham companies do very little market research and most of their designers dont actually use
the equipment that they design. The end result is you end up with useless equipment that is far from flexible.

5 watts output on SSB is almost close to useless with simple portable antennas. Portable SSB starts to wakeup at about 25 watts of power. On CW  5 watts is effective.

Bottom line is  that if you design  flexible equipment that can be configured for many styles of operation you will have  a sales winner. Your transceiver design looks like a winner for building a good portable HF station platform.
The military have been optimizing their HF portable radios for decades,  the result is the HF manpack the most practical portable radio you can find. All ham designers can come up with is useless cutesy radios that are not effective
at doing what they supposed to be doing, that is communicating because they so poorly designed or largely impractical for operating from any other place besides being a near a car or picnic table. The HF pedestrian mobile pioneers from the UK like G4AKC shows the kind of design expertise and lateral thinking thats needed.

I've done decades of QRP comms, often over long paths and for personal as well as professional 'occasions'.  I'm quite familiar with military manpacks, though unlike Mr Z,  I virtually always used efficient antennas, such as the dipole for NVIS through medium range and -yes- a wire halfsquare for long range.

For this transceiver, the math of system gain -v- power show that an increase from this rig's designed output of 5 watts to 20 Watts is only one s-unit at the receiving station, but would significantly change it's size, weight and power consumption for only one s-unit - at best.  That's basically nada for all that increased consumption, size and weight. Personally, I can't see a reason to complain that this is not a 20 Watt rig. If they DO indeed build a different rig at 20 Watts, well then that's GREAT! What's not to like about more cool rigs to choose from?

Small, lite & portable are great attributes for a rig like this. The niche market needs more - this I agree with.  I do DISagree with Z in his recurring idea that 20-25 Watts is necessary for fieldable ham QRP rigs such as this one and the KX-3, which he also has strange issues with. I would highly recommend re-reading his posts re: the KX-3 and then compare that with his statements here, to see the same feelings at work. Interestingly, the math remains constant and still DISagrees with his feelings.

Let's do a little math here:

For a rise from 5 to 20 Watts, we can expect at least the following increase:

 
+Size of the rig due to slightly more circuitry, larger batteries and especially a larger heat sink.
+Weight (see above)
+Power consumption (4 times more power consumed & DISSIPATED on transmit)
+Likely also a change of battery type, due to the need for much higher instantaneous current for voice peaks and etc.
+A much larger heat sink to dissipate the 4x power.
+Higher cost
+Larger recharging system, or 4x longer recharging time.

And reduce the:

Portability
Length of transmit time using batteries.

- and much more.

All this to gain just one S-unit on the receiving end: basically nada.

We had similar discussions on the KX-3 postings.  The math never changed. dB are still dB and four times higher power output in the same class of amplifier operation requires at least 4x more heat sink and battery, as a rule of thumb.  


As for manpack radios - they're FUN for hams, heavy as a box of lead for soldiers and I like them! Carrying one along with a normal backpacking load of shelter, food, water and spare knickers on a camping trip as a civilian is not my idea of fun.  Been there & done that back when I was younger, stronger and thought that a mil rig was the coolest thing since sliced bread.


Feelings vary.  Math does not.


My 2 cents worth. Please adjust for hyper-inflation.

这个项目真实庞大,其复杂程度超出我的预料,还好进展顺利。
等新机发布后,预计短时间内不会再做这样的便携机了,说不定未来几年之内都是行业标杆。

Below is my translation:

The project turned out too be very big. The complexity is beyond my expectation. Luckily turned out quite smooth. I expect not to do any project on a portable rig like this after the release of the product. It (X1MKII??) could the standard in the industry in the years to come!!

New X1M MKII Qrp Transceiver - Available by end of year.
20 Watts kit or assembled.
http://www.kightradio.com/X1M-MKII-20-Watt-QRP-SSB-CW-Transceiver_p_319.html

A kit would be very sweet, even SMT.
(Now that Juma is no longer with us......)

There is a 50w external PA currently available:
MX-P50A FT-817 HF POWER AMPLIFIER
http://www.kightradio.com/MX-P50A-FT-817-HF-AMPLIFIER_p_315.html
Only $279.95 (plus shipping of ?)
(Actually says $359.95 minus “your savings of $50.00")
Wonder if ya gotta buy the transceiver to get the $50 discount??

Says “For the FT-817”. Probably just a marketing tool.
Interesting developments.

I think I'll stick with my K2 until more units
have been sold and more reviews written,
on any of this companies products.
I wish them well, though.

Hmm.  All the photos show a backlit display.  On many QRP rigs cutting the backlight can often reduce the rx power draw in half.

From the operator manual:

"Frequency Range RX & TX .1 - 30 MHz
5 ham Bands configured separately with optimized filters."

What about bands without "optimized filters" - how does a band like 17M perform?

Are there CW filters or just the same receive bandwidth as SSB?

Just got back from Dayton last night (Saturday night).

I bought the X1M and hooked it up this morning about 1/2 hour ago. I worked a CW ragchew on 40 and worked Cuba on 17 meters CW. So far, seems to work FB.

This rig has no CW filtering. No way to adjust your received bandwidth.

Translated via Google:
The overall design brief
     Mass production X1MKII portable HF +6 m shortwave mode radio circuit structure is designed for 3-conversion circuit, the first IF of 64MHz high frequency program, the second IF 455KHz, ensure the performance of the receiver, may arise from a variety of stray fell to the working band, the indicators can reach a higher level. By design, the RF front-end dynamic range of 40 to 45dB, anti-blocking performance is also very good, can withstand about 25dBm input signal directly and not overloaded. Aircraft design, dynamic range 110dB, preamplifier, a put, two discharge can be controlled by the AGC. Impedance matching circuit at all levels, careful matching of design at all levels of the IF filter to guarantee the passband, with fluctuations less than 1 dB, ensure the machine's selectivity and low noise levels. Continuous design of front-end band-pass filter to achieve continuous coverage from 0.5MHz ~ 55MHz. After three converted IF signal is sampled by the ADC into the digital signal processing circuit for coherent demodulation, anti emission process.
    The machine receiving channel a large number of ADI's new models of IC design, so that the overall performance remains at a good level. RF power section uses all the Mitsubishi power tube series, and CNC bias circuit to control the various parts of the amplifier, so that the part of the circuit almost free debugging, and improve the overall reliability of the indicators can be ensured.
    X1MKII motherboard uses a 4-layer board design, the core digital board 6-layer design, the key unit circuit fully shielded, the resulting EMI / EMC improvement is very obvious. Extensive use of digital control and digital modulation and demodulation circuit, in addition to improve the consistency of the product, but also reduce the traditional circuit debugging, to reduce debugging workload and difficult to debug, DIY hands to bring the gospel.

Dale W4OP

I can comment on the X1M (not the MKII) - I think the MKII is a completely different bird than we're talking about here.  It's not just an upgrade, I think it's a completely new design.

The X1M board is very well put together and the radio is simple enough to operate if not a bit fiddly for large fingers or those with sight issues.  Documentation is still a bit sketchy and there are menu options in setup that aren't very well explained (if at all). Receive quality is a bit tinny on the small speaker and headphones are recommended for optimal operation.  The overall build quality is good - but just lacks a tiny bit of finish which still makes the radio look like a kit build.

There are filters which switch in and out in each band segment, you can hear a click when you transition from one to another.  My example is programmed with general coverage transmit although I think that they intend to block that in later shipments. I did read somewhere that the intent was to inhibit transmit outside of ham bands on the US model.

Receive quality on 10-40M is good but I still struggle with the built in speaker.  It does receive general coverage but note that the unit only receives CW and SSB, there are no AM or FM modes.  When using VFO B, the pre-amp turns on and gives weak signals a boost - I believe that this is selectable as you can also use VFO A/B to operate split frequencies.

I have made a couple of contacts so far.  Gotten decent reports on 20M SSB but the supplied stock microphone seems a bit insensitive.  I have read a couple of articles in the yahoo group saying that there are some adjustments inside the unit for microphone level.

The unit is supposed to be IC718 compatible and useable with HRD.  The comm port on the back looks every bit like an RS232 level port but thusfar has yielded nothing with respect to connection to my PC.  It is interesting to note that I did notice a marked increase in noise and a few extra birdies while I was testing this feature.  When I disconnected the cable the noise went away.  The manual doesn't say anything about the levels (TTL or RS232) nor does it give any pin outs related to the connector.  At this point I haven't tested PC control.

It's no KX3 or FT817, but for the fairly slim price of $300, it's a great little radio and I'm very happy with it so far.  I intend to pack it with me when I travel along with a lightweight set of dipoles and a small rechargeable battery pack.  I'll post more when I get a bit more experience with the unit and will post a review once I'm satisfied with my initial findings.

Hope this helps.

How good (or bad) is selectivity?

And the best:
INTERNATIONAL ORDERS
We will be happy to ship to other countries however we can not accept "Credit Cards" Payment must be made via Bank transfer or Western Union Only

yes of course, sound trust.

Sound business.

if you want a good QRP transceiver just go for elecraft K1 or K2.

I bought and built a K1 4-band, but can't figure out where to plug in the mic for SSB.  As for the K2, if you go three times the price it's not really a justifiable comparison.  This little radio could fill a niche nicely.  I've just moved into digital communications, and if this could be made to work, it's one I'd consider for remote digital (or other) operation -- I'm not inclined to leave my main radio on when I'm away from the QTH, but a cheap second PC and a rig like this, might be worth doing.  It would also become a second radio for mobile set up with the K1-4, the reason i bought the K1 kit (though haven't actually done much in the way of mobile set up yet).

Here is the translation of the specs for the MKII

X1MKII mass-produced portable HF +6 m shortwave radio whole section full mode circuit structure designed as three times the IF DSP inverter circuit, a first intermediate frequency is 64MHz high frequency program, the second intermediate frequency is 455KHz, great guarantee of the receiver performance, it may also produce a variety of spurious band fell into work, the indicators can reach a higher level. By design, the RF front-end dynamic range up to 40 ~ 45dB, anti-blocking performance is very good, can withstand direct about 25dBm input signal is not overloaded. Machine design around 110dB dynamic range, preamp, an intermediate level, two intermediate level can controlled by AGC. Circuit impedance matching between the various levels are done, carefully designed to match the levels of the IF filter

I have had mine going on 2 months now and can say it is probably the most fun I've had in my 36 years of ham radio. I have worked about 20 countries on 15, 17, and 20 meters SSB. This all with a ground mounted 5BTV antenna. Haven't tied it on CW yet just because I'm a little rusty at CW.

The overall design brief
     Mass production X1MKII portable HF +6 m shortwave mode radio circuit structure is designed for 3-conversion circuit, the first IF of 64MHz high frequency program, the second IF 455KHz, ensure the performance of the receiver, may arise from a variety of stray fell to the working band, the indicators can reach a higher level. By design, the RF front-end dynamic range of 40 to 45dB, anti-blocking performance is also very good, can withstand about 25dBm input signal directly and not overloaded. Aircraft design, dynamic range 110dB, preamplifier, a put, two discharge can be controlled by the AGC. Impedance matching circuit at all levels, careful matching of design at all levels of the IF filter to guarantee the passband, with fluctuations less than 1 dB, ensure the machine's selectivity and low noise levels. Continuous design of front-end band-pass filter to achieve continuous coverage from 0.5MHz ~ 55MHz. After three converted IF signal is sampled by the ADC into the digital signal processing circuit for coherent demodulation, anti emission process.
    The machine receiving channel a large number of ADI's new models of IC design, so that the overall performance remains at a good level. RF power section uses all the Mitsubishi power tube series, and CNC bias circuit to control the various parts of the amplifier, so that the part of the circuit almost free debugging, and improve the overall reliability of the indicators can be ensured.
    X1MKII motherboard uses a 4-layer board design, the core digital board 6-layer design, the key unit circuit fully shielded, the resulting EMI / EMC improvement is very obvious. Extensive use of digital control and digital modulation and demodulation circuit, in addition to improve the consistency of the product, but also reduce the traditional circuit debugging, to reduce debugging workload and difficult to debug, DIY hands to bring the gospel.

I been looking for info on it myself and found no updates. I did note 4 new videos on YouTube in the last two weeks. Just put 'X1M QRP'   in search and sort by new, there videos of the X1M Platinum Version and Regular Version.

I found a Aussie site called 'spook tech engineering' that is selling the X1M Platinum radios for $350 AUD Pre-order (I am not connected to the site...just passing out info).

 Yes reliability is an important consideration. It appears the Youkits have generally been well received. Maybe the X1M will be the same?


I think there is still a gap that needs to be filled. Something self contained with batteries, tuner, power supply , (usb port like the IC 7200) and whip antenna like a Manpack type of radio that will do QRP and up to 20 watts if needed.

 A cross between the SGC 2020, IC 703, FT 817 and Elecraft KX3, built like a tank yet relatively light weight.  Something like the VX 1210 by Vertex but at half the price.
