Excellent UIV32 rig! 
|
Time owned: 3 to 6 months
|
|
When bort i qequested the rig be set up with tnc and digital transmission for general use in packet eg UIV32. Have had some good work with it into almost all SATS using path ::Cq v ariss,myqra,mycall: so have no regrets and all this on only 5w out. On repeater working the audio is reported as excellent so i am well pleased with my purchase. Very good rig, gets hot but the fan is man enuf to cool it down:)

Simple to operate Dual bander with Xband REPEAT 
|
Time owned: 0 to 3 months
|
|
The unit is easy to program and has sensitive reception. I would prefer a true squelch knob. The scaning programing does not have banks and the speed of scan is MUCH slower than my Icom 208H. I live in country and intermode is not an issue. The unit will not tune freq lower than 136.000, but may be my problem. Crossband repeat is GREAT feature.

Excellent Dual Band Full Duplextransceiver 
|
Time owned: more than 12 months
|
|
This is the most user friendly 2meter-70cm transceiver I have ever had in my hamshack.Controls are user intuitive without getting out the owners manual. I've had no problems with intermod as some users have stated.I guess that I live in a good location! I love this radio! W5SSC Scott.

Bad intermod, really bad 
|
Time owned: 6 to 12 months
|
THE problem with this tranceiver is intermod. It's bad, really bad. It's impossible to use this thing at home, as not even a reasonable signal can be heard on 70 cm due to all kind of out-of-band signals it should ignore. On 2 meters the Alinco performs reasonable.
I gave it one point, because it's very user friendly and complete. I would kill for a trx with the quality of a Yaesu 7800 and the user interface of this Alinco...

I couldn't use it at my QTH due to pagers breaking through. Replaced it with a Yaesu 7800R and had no problems.

Intermod is terrible. 
|
Time owned: more than 12 months

I guess it you put this rig out in the country, far far away from any public service it would be better. This is exactly what I did and it just was OK, not much better. I had a DR-600 that I completely wore out in my work van and it never missed a beat. It looked much better on the test gear than the 635. I thought Alinco was trying to improve??? The 600 was beat up, abused and it still is working for its present owner. I did have to replace some caps in the memory circuit. I gave it away to a new ham in the 11th grade. He just completed collage and it still is working.

Great Dual Bander 
|
Time owned: 6 to 12 months
|
I have had this rig for over 6 months now. It has been a great rig for me. I travel from a "Radio Friendly" area to a "not very friendly Radio" area, and cross a highly populated airport area. It works great for me. I do hit one spot of high intermod, but I have owned various other rigs, and this rig is right on top of the others in all cases. It receives great, it transmits great (by on the air comments) and is just a great all the way around rig. I love all of the memory channels, and the fact that it receives outside of the normal HAM band freqs including Aircraft. I love the seperate transmit and receive colors of the display, so that you automatically know when you are transmitting. This has been a great rig for me and plan on putting it in as a base station here at the home QTH very soon to see if there is a very big difference, but I feel that it will only improve. I have tried the "Crossband repeat" and it works like a charm. "I hope that it never happens" but if there is an emergency situation that comes up where an emergency situation comes up, and hams are needed with the capabilities, it will get a real good test. Otherwise KUDOS to Alinco and their design team on making a great "All the way around rig", and hope that they continue to do so. With all of the new ideas, bells, and whistles they came up with on this rig, it shouldn't be long before they come up with another rig that "out performs them all", by a land slide. For someone just getting into the hobby, and looking for a first rig or a reasonably priced "Dual Bander", here it is. I hope you have as much fun with it as I have.

Be fair!

In fairness, the DR-635 is a great radio with an expected few problems. No radio is perfect or flawless and packing so many features into a one small box (cuz that's what we ask for) means some compromise. Intermod is a likely problem given the high gain and very broadbanded front end. I've noted this problem only on one or two frequencies, certainly not all. Thus it is only a problem for me when passing through metropolitan or high RF areas. On the unmodulated carrier front, when you build two radios into one box basic RF design principles dictate you will have birdies and carriers on some frequencies. If you do the math, the frequencies mentioned as problems are divisions or multiplications of 3. Thus it is not an Alinco problem, it is a frequency/basic electronics problem. You can only do so much filtering and shielding to take care of that problem and to have only a handful of frequencies at issue is not bad. Other radios have similar issues but to say the DR-635 is a bad radio when it has so many great features is unfair. Just think of the older single band rigs of the past. They had virtually no other features but lots of quirks! I had one Genave crystal controlled 2m FM mobile rig that received German shortwave radio (in Maine) just fine! Talk about intermod! To fix the PL unlock problem when scanning 70cm and transmitting on 2m, do a full CPU reset. This is a quick fix but does require reprogramming memories. Just like your PC, the 635 has a CPU with a program. Periodically, it needs to be rebooted!

BAD RECEIVER DESIGN 
|
Time owned: 3 to 6 months
|
I purchased the DR-635 in May of this year, primarily as it had dual receive, which meant that I could have both our club's 2m & 70cm repeaters tuned in simultaenously. The rig also appeared to be good value for money. Wow, what a dissapointment - I should have read page 59 of the manual first! A "feature" of this rig, when certain combination of frequencies (e.g. 145.700 & 438.800) are tuned in creates a carrier on the VHF frequency, making it almost impossible to hear anything on the VHF frequency.
The rig is also prone to intermod big time!!
I would rather pay a bit more a get some descent quality.
