Great First Rig  Time owned: 0 to 3 months
This review is being written by a "hampster" new to HF but I will give you my .02 anyway. I received a new DX-77 about a month ago and finally got to use it this weekend. I am not disappointed. I chatted to Denmark and Japan on 12 meter, made at least 13 contacts (different states) stateside in just a short time. Almost all my reports were at least a 59. I made one contact from Oklahoma to So. California and after the QSO realized I was on low power. He gave me a 55 report. I am really impressed with the radio. I have a neighbor with a high dollar Icom and we get similar reports. I am impressed with the radio but, again, I am new to all of this and as my experience grows will probably have some hind sight. Bottom line....I don't see how you can go wrong with this radio as a FIRST set.. Price is right, performance (so far) is wonderful. 73.

Great first HF rig  Time owned: 0 to 3 months
I've had the Alinco DX77-T for a little over
one month and it has worked great for me. I
wanted a low-cost rig with the most features
for the buck. I operate primarily CW so the
included filter has come in handy occasionally.
Sometimes its too narrow to pick up anything
but the really strong signals though, so i
usually turn the filter off. I'd like
to be able to directly input a frequency, but
i wasn't willing to pay the extra $$ for it.
Overall i give this radio a 5/5. If you're a
new ham and looking for a first rig, or you're
just looking for something that's not too
expensive and can be hauled around (ie: field day)
then this rig is for you.

Best rig for the money!  Time owned: 6 to 12 months
I owned the DX-70 when it first came out, but had to sell it due to unforseen circumstances. I vowed to get another Alinco when I could afford it. As luck would have it, I found a DX-77T used, but had never been out of the box.
I have nothing but compliments for this rig. I really like all of the accessory jacks being on the front, I don't have to suffer with trying to get a mirror and look in behind while trying to insert plugs.
The CW features are outstanding. A built in keyer, full QSK, auto delay, 500 Hz CRYSTAL filter. (Whew!) And all standard equipment!
A superb general coverage receiver. 100 tunable memories (102 VFOs!!), that store all of the parameters you set such as mode, filter, etc., and band-stacking registers. The ability to store split freqs (although I can't ever recall having to ever use the exact same freqs for the TX and RX). Setting a split frequency is the easiest way I have ever seen. Just hold the split button until the display shows all zeros, the dial in the appropriate amount of split, whether it is plus or minus, release the button, and scream away to the DX.
A couple of minor problems (what rig doesn't have them?). The first is having to cycle through all of the modes to get to the one previous to the one you were using. (The DX-70 had discreet buttons for each mode).
A rather awkward method for zero beating CW (according to the operator's manual) is holding the FUNC button while simultaneously holding the key down AND turning the tuning knob until zero-beat is achieved! Makes my fingers cramp just writing about it! I find it easier to set the PTT lock on, then hold down the key as I zero-beat. After zeroing in, I turn the PTT circuit back on and key away. It was much easier on the DX-70 because all I had to do was tune the radio while switching from CWL to CWU, back and forth until zero beat, due to not having to cycle through all of the modes. Having a button dedicated to each mode would be nice in the DX-77.
Another problem seems to come from filter blow-by. When I am listening to SSB, stations lower in frequency than me, sometimes as much as 5 kHz away(on USB, vice versa for LSB) appear to be splattering. This happens mostly when a high-powered station is operating. I suspect this may be due to the SSB filter being audio in nature, rather than in the IF stage, as is the case with the CW filter; please correct me if I am wrong. The DX-70 had a very narrow SSB filter, so I didn't notice the same problem with that rig.
I found that the low power setting, using the front panel button, is 10 watts whether the internal power switch is set to 50w or 100w. So much for a QRP use, unless on SSB. There is a way to set the low side of the power setting even lower by adjusting a small pot next to the internal power switch, but if I did that, then I would have to send my HW-8 packing. (Not bloody likely!)
All of thes are annoyances, rather than major problems. I still enjoy the radio very much. Heck, I still use my HW-8 alot for QRP, and it's not near the rig the DX-77 is!
I considered getting the Icom 718 and the Yaesu FT-840 also, but they lacked the features that the DX-77 had. I don't really care if it doesn't have keypad entry for frequency hopping. I love to spin the knob slowly, looking for weak signals.
Overall, the DX-77 can't be beat for the price one pays, considering the wealth of features included as standard, which are high priced options on other manufacturers top flight rigs. I would not hesitate to buy another DX-77 or recommend one to a ham that solicited my opinion on a rig to purchase.

Great little rig!  Time owned: 0 to 3 months
Great little rig. Love it more and more every weekend I own it. Uncle Sol has helped alot, but this rig and a G5RV antenna has worked better for me than the previous two rigs and antennas (both more $$$).

Two small problems, all rigs have some. The AGC causes some audio distortion on SSB. It is not all that bad though and only happens on some signals (read WB1FPA's review and use his mod to eleminate problem). Alinco has aparently done a lot of modification to reduce the problem. Suspect many users will not even notice the effect on current production units (I am picky though).

Secondly, the noise blanker either does nothing at all or causes a little popping noise (useless).

There is far more good than bad on this one. The DX77t has a great little receiver. It is simple to use but seems to have most of the essential features. Would definately buy this rig again. A

Very good value.  Time owned: 0 to 3 months
Alinco DX-77T (#T000882) by Tom Howey WB1FPA
In Price Range Rating = 5 (Overall Rating @ 4)
-____I received my DX-77T about mid-June 2000. I quickly placed the unit on the air and solicited comments on Tx audio and while observing the receive audio. I have an Alinco DX-70T in my vehicle which I had used at home for a couple of years. The only notable shortcoming of the DX-70T was the 1 kHz narrow SSB filter doing double duty as a CW narrow filter. It worked, but not too wide when the bands were crowded. So I decided to give the DX-77 a go.
-____All the oscillators in the DX-77T are either controlled by or directly generated by Direct Digital Synthesis (DDS). The two DDS chips control the up-conversion from signal to 71 MHz conversion, the 71 MHz to 8.8 MHz conversion, and finally the 8.8 MHz "BFO" for demodulation of SSB/RTTY/Digital and CW. This final DDS also creates the needed signal when converting from 8.8 MHz to 455 kHz for the FM mode. A neat & tidy arrangement. The QST product review indicated fair to good oscillator noise performance. The DX-77 shares a characteristic of the DX-70T. You turn it on, its ready to go from a cold start. Very good stability. Even more impressive on a cold New Hampshire morning when the DX-70 is ready to go & on frequency right away. You don't have to buy any accessories for this, it comes standard. Nicely done & on a budget at that. What would a 'top-end' Alinco look and perform like?
-____The Receiver has good sensitivity and low background noise. With the preamp on & dipole connected, antenna noise is clearly audible on all bands. As supplied, my DX-77T had some annoying distortion on SSB receive. You could hear the raspy distortion on CW signals as well when listening in the LSB or USB modes. A 1 uFd monolithic ceramic capacitor was placed from the AGC testpoint to ground on the 'main' PCB and the distortion was gone! The AGC slow and fast time constants and Tx/Rx turn-around seemed exactly the same . To be certain, I'll pass this information on to Alinco for their consideration. If you decide to try this mod, enter at your own risk. I don't know if it would void the warranty and since this is a surface mount PCB, extreme care is called for. My DX-77T & its excellent 2.7 kHz IF filter now has very respectable & enjoyable SSB/CW receive audio. I don't know if only my unit has this distortion or if it is common to all the DX-77's? Seems like it must be just my unit since distorted audio wasn't mentioned at all in the other reviews.
-____The AM reception is actually quite good. Of course a 8 kHz bandwidth is too wide for SWLing on allot of crowded bands, but if the frequency happens to be clear on both upper & lower sides, then the sound is wonderful. As with many other radios, the DX-77T offers the user the SSB filter for AM reception use. The difference in the DX-77 is that the 2.7 kHz filter is a very acceptable AM narrow filter. Tune 1.3 kHz up or down from center and the recovered signal is good, and the skirt selectivity of the stock SSB filter is excellent.
-____Although the DX-77T comes well equipped for FM, I've not had a chance to test it. Just haven't heard any 10M FM at all, yet. Not even repeaters. So much for a solar peak. The circuitry in the DX-77 is very similar to the DX-70 so I expect the same good FM performance. The 8 kHz bandwidth should excel on FM.
-____The Tx section passed the WB1FPA chassis radiation tests. No RFI on nearby TV's when running into a dummy load. It would surprise allot of people to find out some of the rigs I've tested over the years & found them to be poorly shielded. Does anyone out there remember the 70's QST cover showing the Kenwood TS-520 inside copper screen while being tested for excessive chassis radiation? No one I've spoken to at ARRL so far remembers. ARRL does not check the rigs for this problem anymore. Perhaps they figure that everyone has cable-TV or satellite-TV. One rig I tested caused TVI to TVs on cable! I think its a test that is worthwhile to do. If you live in a TV fringe area you'll be happy to know that Alinco takes RF serious and the RFI stays where it belongs, inside this well shielded radio. Both the DX-70 and DX-77 were in amongst the best shielded radios I've tested over the years.
-____Like others, I too have received reports of very good SSB Tx audio. If any mic gain adjustment is needed for your voice & location, do it with the speech compressor on. I found that adjusting with it off meant that when the compressor was enabled, the audio was too harsh. About the only way Alinco could improve SSB Tx would be to better suppress the "talk-back" heard in the speaker or headphones when transmitting. While it is tolerable, the radio deserves better than letting this go unattended. A review of the AF circuitry shows that Alinco did place a transistor configured as an electronic filter in series with the voltage going to the audio amplifier, but some how the squawk gets through. I double checked to make certain that a DC power supply ground loop was not causing the problem, and finding no ground loop, I concluded the squawk was internally caused.
-____The CW Rx and Tx on this rig is super. Not only did Alinco supply the 400 Hz CW IF filter, but there is the same audio filter that's in the DX-70 in the DX-77T. No hiss, just signals. Adjustable sidetone/offset is excellent. One minor drawback is that the TR relay is noisy, but if that is what it takes to give full break-in on a budget radio, count me in. PS; low power in the 50 or the 100W position is about 10W, not 5 in the 50W position as was reported in QST (unless the Alinco people made circuit changes.
-____My overall rating is a 4.5 due to the squawk-back on SSB Tx, the distorted SSB Rx I fixed (although if its only my unit, then I retract my complaint), the fact that the CW filter can't be used on SSB for the digital modes and the noisy TR relay on CW break-in. Clearly though, in its price range, never has so much solid performance been brought to the marketplace at such an affordable price. I'd definitely by another!

HOORAY ALINCO  Time owned: unknown months
After a month of constant use, I can say it's the best rig for the money I have ever had. CW is flawless, filters on CW and SSB are remarkable. If you don't have one, you are missing the boat. I've owned the finest of Kenwood, Icom, and Yaesu, now,,,I have the best of the finest..

A REALLY BIG DEAL IN A SMALL PACKAGE  Time owned: unknown months
I have owned one for one week now. Find that it is an excellent rig. NO problems with CW dits or dahs. It performs great. Needs to have KEY, SPEAKER, on back rather than front. Needs MIKE GAIN control. Otherwise, a terrific little rig, just right for new ham or old geezer like me. This one is absolutely a fun little rig...

Great rig, performs as advertised!  Time owned: unknown months
I have owned my DX-77T and EDX-2 automatic antenna tuner for 18 months. I use the rig for SSTV, PSK31, CW and SSB. It is connected to my Computer logging software (LOG-EQF) for automatic Logging.
I have come to EXPECT unsolicited compliments on my transmit Audio. I am using a "computer" Electrostatic microphone / headphone combination ! Just bridge JMP-1 (next to audio gain control) to provide the +5v to the electret mic.

Good: I agree with the comments above. I.F. Passband slope tuning is very useful.

Bad It will not do CROSSMODE split. Built in speaker on mine is junk, I use an external speaker when not using headphones. Another KNOWN bug is the Noise Blanker. It can make signals sound terrible under certain conditions. There is NO externally accessable Microphone gain control.

Summary I would buy another one. BE CAREFUL to get the correct model. One ham store is selling a model THAT DOES NOT include the CW filter.
