Survey Question
Current Survey Question

R.F.I.---the continuing scourge of Ham radio, be it "traditional" horizontal oscillators of TVs going back to the 40's, or the raucous din of to-day's plasma televisions, exercise equipment, lighting systems, furnaces, electric fences, power line leakages, AD NAUSEAM. How have YOU handled cases where somebody's electric contraption seriously hampered YOUR on-the-air activities...?

Manager - VK5LA
Andy Williss (VK5LA) Welcome to the Survey Page.

The goal is to help us all gain a
better understanding of the ham
community... what we like... what
we don't like... about various
aspects of our hobby. Let's make
it fun and maybe kick up a little
dust once in a while. I hope you
all will participate and enjoy the
questions.

Please enter your ideas for future
survey questions yourself (click on
the "Enter your idea" link just
above) or send them directly to me
at surveymaster@eham.net .

I often get comments that there is
a commercial interest in the survey
questions and that some of the
questions are "rigged"...I assure
all eham users that the questions
are
in no way influenced by any
company, person or persons.
The questions in the survey all
come via contributions to eham or
are just plain made-up by your
humble survey manager.


Please note that there are many
potential surveys in our queue, and
many of them are duplicates.
Sometimes we combine several
questions into one. We at eham.net
make every effort to present all
content in a way that will be
easily understandable and useful to
an international audience.

The proposed new 500-KHz (600- meter) band: are you thrilled at the prospects of getting on & using it...?
  Posted: Apr 03, 2013   (1093 votes, 51 comments) by VE3CUI

  YES! I'm ready to have the title of "Topband" relinquished from 1.8-MHz, and to see it bestowed upon 600-meters...
  NO! The LAST thing Ham Radio needs now is a brand new band, no matter its location in the RF spectrum...
  YES! I can't wait to see who'll be the very first WAS award reipient there---maybe even WAC...?
  NO! I have ZERO INTEREST in ANY band whose antenna can't be placed atop a rotator at 50-feet...
  YES! I absolutely LOVE delving into low frequencies: what a privilege and challenge, both...
  NO! I can barely get a signal out on 160-meters---600-meters is just out of the question for me here in suburbia...
  Huh...? What's 600-meters, and who really cares, anyway...?

Survey Comments

Ditto W4KYR...Love the thought of experimenting with "low freq.", but I live in the city so it would be impossible here, but I dream of finding a friendly rural resident who would let me set up an antenna on a semi-permanent basis to "play".

Posted by KB3ZAA on November 1, 2013

630m? No way! Only Merlin the magician can do 160m from a city lot!
Even if one can lay of sufficient ground
radials and construct a vertical structure
capable of withstanding relentless Texas
winds and tall enough to have some usable
efficiency dooms those living on small city
lots who want to participate in 630 meter
activity to receive-only operation using
active antennas and small tuned RO loops I'm
afraid ... then there is the ever-present
noise from electronic 'devices' today ...
further dashing any hope of enjoying even
receive ops on 630 meters for a great many.
But still, I see it as a new frontier and
wish luck to those venturing into it.

630 Meter Band
I have all the equipment built and ready to
get on the air , from an urban lot . Have
been holding off waiting on the FCC and ARRL
to make the ham band happen . It has been so
long now , I am just going to go ahead and
get a part 5 license and join the fun . Yes I
know EXACTLY what to expect . I have run a
part 15 , 1750 meter beacon with 1 WATT INPUT
into a single vertical wire just under 50
feet tall and have had some amazing "DX"
captures using QRSS60 . Time we catch up with
the rest of the world .....

600 meters...again
FYI, anyone who owns one of the old "ARC-5" LF receivers, the BC-453 or the R-23/ARC-5, already has a high-quality receiver for that band. Dig it out of your "junque" pile and give it a try. You'll be amazed. I use a BC-453 with Spectran and my shack computer. It works very well, indeed.

Posted by W7EKB on May 2, 2013

630 Meters
I just completed my first season on 630m after applying for a Part 5 license last September.

For the 300 or so that have voted at this point that they likely would not have room for an antenna, take heart! Plenty of stations have made this band work with verticals as short as 18-20 feet with lots of top loading. As others have said, some digital modes excel at these frequencies. If you already have a dipole or vertical on 80 or 160, there may be some reasonable options! I am using a 72 foot tall T-top vertical with 130 - 100-foot radials and with 1 watts ERP have been heard on WSPR from coast to coast and regularly complete CW QSO's with stations equipped to receive. My ground wave range at noon seems to be about 210 miles, so there are definite possibilities for even the modest station. Don't discount the band - have a listen down there. There are quite a few of us still active on WSPR as we move into the noisy spring and summer months so you may be able to assess just what your station capabilities are.

Many options exist for transmitters, transverters, amplifiers, and receive converters as well as information for how to wind loading coils.

If you are bored with so much of what ham radio has become, 630m (and 1750m and 2200m for that matter!) really will get you back to your roots and let you enjoy some nostalgia and what it means to really be an operator (and builder!)...

600 meters
My 600 meter antenna is a base-loaded vertical, 55 feet tall. EIRP is nothing to brag about, but it works...and doesn't take up a barnyard either. I am presently licensed as WD2XSH/24. Ken W7EKB

Posted by W7EKB on April 30, 2013

600M
Been operating there for almost a year under a Part 5 Grant as WG2XKA. A modest station with good receive capability will open an entire new world! You don't need a rural farm-size lot for an antenna system either...keep an open mind!

600m
On receive my 600m rx antennae is an active E field device just 2ft tall hitched up a birch tree and on a good day with the wind behind has heard Lousiana and the East coast on 600 from XSH and XSG part 5 experimenters 4-5K Kms away, so on rx nothing too elaborate maybe needed. On tx load up the wire and youll be suprised - Using data modes and appx 5W ERP expect nighttime ranges on fair to good evening of over 2000Kms depending on your geo lat/noise. Good luck and Im looking forward to this band AND 137kHz becoming available in the USA

Posted by KL1X on April 30, 2013

Try listening on 630m
I have been receiving signals on this band for
about 6 years and enjoying seeing what can be
copied. WSPR and other modes have shown that
it is possible to decode signals from E to W
coast and AK. As for CW, it is good for
several hundred miles with 100 watts or less
power out of the rig and even with short
loaded antennas. Check it out next fall when
it gets busy again.

630 Meters
Plenty of equipment ready to go on the air , been waiting and waiting for the USA to catch up with the rest of the world .
Been running Part 15 on 1750 meters for years and could never get accepted into the ARRL & the good Dr. Fritz's , 600 meter program , so I have some nice equipment built up and antennas all ready to flip the switch .

W2DI response
To answer your question on who will be the first to have a 600 meter to 70cm dream machine. I will bet it will be an SDR. (Software Defined Radio). The future of amateur radio. Not a discrete radio.

Posted by KB6QXM on April 29, 2013

600 Meters
The real question, IMHO, is who will be the first to
offer the 'dream machine' 600M to 70cm, all band, all
mode, DSP, fixed station/portable/mobile Transceiver
with internal, wide-range automatic antenna tuner?
The ICTSFT-60070-DAT. For under $1,000, after
coupons. Then I'll get excited.

Bring it on! Hams are resourceful and up to the challenge.

things all began! :)

5 mhz
"The manufacturers can't keep up with the changes, so quit changing. 60M has rigs that won't put out over 50W, rigs that put out 100W, rigs that have all 5 channels correct, and rigs that have only 4 channels correct. All because the ARRL/FCC kept changing things"

The FCC made 1 change in 60 meter frequencies and modes in 10 years. The ARRL has no authority to change things for 60 meters. I do wish they would issue awards like WAS for 60, though.

Low bands are tough because of the exhorbitant
size of antennas. Maybe just some monitoring of
those frequencies.

We can all whine about his survey, but at least he superseded the last survey in ONE WEEK. That must be a record.

I'll take it back though if this one lasts into May.

Posted by N3EG on April 21, 2013

Operating a station at I.F. frequencies offers possibilities limited only to the imagination. Think of the digital modes that act as if magical with a barely perceivable signal. Operating with a homebrew DC receiver where a lumped-constant notch can remove the "unwanted side" and building RX up-converters, transmitters and transverters. Learning how to optimize an antenna system for maximum efficiency at VLF. RX amplified loops, kite, ultra-light, stealth balloon antennas. Almost feeling like a "Spark" did back in the day. Priceless. I'm in! - Tony WW2W

Anyone else catch the comment by KU2US about his Alinco being "unlocked" and covers 60 meters and he could work 600 meters?

As for an antenna, wonder if I could load up the railroad track (unused) behind my house?
Talk about ground wave....

Hmmm. I'm looking at railroad tracks along the back of my property. Wondering if I could load that up?

I doubt an "unlocked" Alinco that works 60 meters would do. Anyone else catch that?

530 Khz
As an aide, 530 Khz has hundreds of low power information stations. These signals can be used for equipment and antenna adjustments, etc. And I suspect there may already be some beacons in that area.

Yet another potentially noteworthy and useable poll wasted with poorly drafted distractors, bordering on the assinine.

The only surprise is that it wasn't published on April 1st.

Are you kidding! I had a hard enough time with the HOA to allow a G5RV (half wave). I can just imagine that if I went back to them and requested a dipole that was 2 miles long. Maybe I could get the HOA in the next subdivision to buy in as well.

600 Meters
I barely have room for an 80 meter wire antenna, 160 meters and 600 meters is out of the question totally!

Posted by KB9TMP on April 9, 2013

More Low Frequency allocations, please!
In my opinion, low frequency operations separates the real hams from the appliance operators. I have been involved in the Lowfer hobby (160-190 KHz) since the 1980's. I had a real low frequency receiver since the 70s. Receiving weak signals due to the limited power, the antenna sizes or loading due to wavelength is challenging at best.

To me, low frequency harks back to the beginning of amateur radio where hams had to know in-depth electronic theory and at the time, CW. Either you did it, or you found another hobby.

Do I believe that 600 meters will really catch on? No...not for the majority of ham radio operators. The technically inclined and electronic engineering-educated will probably get involved. In my opinion, the majority of hams would rather do contests, chasing DX etc. (you know.... You are 5/9, QRZ)

I look forward to hams getting involved with the band. I would also like to see hams get other low frequency allocations, maybe near the Lowfer band or lower.

The world of Longwave below 500Khz is very interesting and mysterious. If anyone wants any more information about longwave, go checkout http://lwca.org. (Longwave Club of America)

Good Day W4KYR...
So is it safe to assume that we might soon collectively
benefit from seeing one of your own well-crafted surveys
on this site, and in so doing, learn how a good one
SHOULD be written...?

Your three proposed questions are all in the affirmative--
-what if someone is predisposed to never to take part in
any 600-meter operation, for whatever reasons...? You
don't make that option available, and in so doing, ensure
even more non-participation.

Sorry, but I have no links with any professional polling
corporation: I'm just another Amateur radio operator with
an inquisitive---if sometimes imperfect!---mind...

Posted by VE3CUI on April 8, 2013

Missing Questions

The Survey is missing these questions.

Yes. I'd like to try out 600 meters someday.

Yes. I plan to try out 600 meters within six months.

Yes. I plan on trying out 600 meters as soon as I gather the equipment and extra wire.

I did not participate in the survey.

Posted by W4KYR on April 7, 2013

600Meters
My Alinco DX-77 base rig is unblocked for 60m and MARS, so I can work it, BUT, again like other posters it is the antenna! Like +/-800 feet at 1/2 wave? or +/-400 feet 1/4 wave? Maybe a helical wound antenna might work. Hey a weather balloon! OH, FAA approval, I forgot. I still would like to do it, it should be fun..

Posted by KU2US on April 7, 2013

600 m
Most hams just don't understand what this means to alot of us ole Merchant CW ops.
It's like a candy bar: SWEET

Posted by NY7Q on April 7, 2013

At last ...
Finally ... an opportunity to either use or sell my RBL-3, and a simple CW transmitter for the new band should be a nice evening project. 500 KHz ought to be fun to try out anyway even though 90% of us will have virtually point source antennas.

Posted by K4IQT on April 7, 2013

Poor answers offered
As others have already pointed out, the possible answers offered are quite limiting. There is no choice for those of us who are simply interested but not wildly enthusiastic or dead against such operations. I do look forward to possible attempts to use the new LF band.... probably with one of the new digital modes such as JT9.

You have to be kidding. I barely can get 40M on a 36' x 100' lot. I'd love to have many acres. Maybe if I win the Powerball.

Several years ago I paid $5 for the carcass of a 100 watt stereo amp to provide the power supply and heatsink for an LF transmitter or transverter. It has taken up room in my basement since.

I'm always elated to see new bands being added,
but I doubt that I will be active on 600
meters. But, I see the band being a good,
technical challenge for anyone who wants to
explore the long waves! Unfortunately, as
usual, the available choices for the survey are
too skewed to express my feelings.

Posted by K1ZJH on April 6, 2013

600m
I can see it being interesting for listening, like 160 or some of the exotic bands. You could make a shielded loop and make a pastime of seeing who you can hear. Now, putting out an audible signal is gonna mostly be the people with acreage, lots of it.

Posted by W8AAZ on April 5, 2013

ANOTHER answer...
I AM interested, provided I can get up an antenna that big.

Posted by WD8OQX on April 5, 2013

Time Marches On, I Guess...
I think I'll miss the title of "Topband" being relinquished
away from 1.8-MHz, to the new segment...

...And I agree with N4VNV: I hope that the authorities
make it a "true" Ham band, & NOT some channelized
abomination, with power limitations being gauged by
"ERP", or "Milliwatts-Per-Metre", ad nauseam, the latter of
which Industry Canada imposed here upon Canadian
experimenters delving into the Lowfer band of 160 -
190-KHz.

Make it an honest-to-goodness power limitation based
upon "...watts input to the final", the same as it is
everywhere else...

Posted by VE3CUI on April 5, 2013

Huh??
I don't have acres of land that can be used for stringing antennas, and I don't see paying as much for wire to make an antenna as I do for the rig to work it!

600 Metres
600 metres what great fun, I can at last use the lower bands on my AR88LF receiver here in Napa CA, don't know about all the man made interference down there though. Bring on 600 metres NOT meters

Posted by G3UXB on April 4, 2013

600M Band
Whatever is decided, please don't screw it up like has been done to the 60M band. Make it channelized, then DON'T change any frequencies. And don't make all the channels open to all modes. The manufacturers can't keep up with the changes, so quit changing. 60M has rigs that won't put out over 50W, rigs that put out 100W, rigs that have all 5 channels correct, and rigs that have only 4 channels correct. All because the ARRL/FCC kept changing things.

Posted by N4VNV on April 4, 2013

600 Meters
These surveys might be more meaningful if the options were designed a little more carefully. For example, there should be a voting option for "Somewhat interested, but waiting for details, practical articles, etc" for the 600 Meter question.

600 Meter Band
After using 425 to 512 kHz while a Merchant
Marine Radio Operator aboard cargo ships, I'm
aware of the great propagation the band offers.
It will be a pleasure to operate there again on
a ham band.

Posted by W5RE on April 4, 2013

600 Meters
Any new spectrum is desirable. Maybe I can use my Collins TCS-12 Military Surplus receiver for something other than SWL and a good use for that 190 kHz to 500 kHz ARC 5 receiver that has been collecting dust. Now all I need are some ideas and plans for a transmitter.

This really sounds like fun to me!
