SG-2020 ADSP2 - Best DSP I've ever heard!  Time owned: 0 to 3 months
I recently purchased an SG-2020 that had just been upgraded with ADSP2. I've thought about a '2020 for quite awhile, and jumped at the chance to get one at a very good price. The rig worked great, except that I was getting rasping sounds in the 500 hz DSP CW filter, and crackling on SSB at full RF gain. I could get around these problems by backing down the RF gain. This is characteristinc of overloading the DSP chip.

So, I opened up my SG-2020 ADSP2 and clipped the audio input wire to the ADSP2 (the green wire in my rig). I put a 100K pot in series with the input. Then I put the rig on the antenna and listened to several stations while adjusting the pot until the 500 hz dsp filter sounded good (got rid of the rasping). This also coincided with the elimination of crackling on SSB. I took the pot out and found it to be right at 15K, so I soldered a 15K resistor in its place and covered the resistor and soldered wire ends with heatshrink tubing.

Bottom line - OUTSTANDING performance! I can now operate at full RF gain on CW and SSB. I can't believe how good everything sounds. This DSP sounds better than all others I have experience with (W9GR, DSP-599ZX, internal IC-706MKIIG, internal FT-1000MP MKV, Clearspeech Base). If you don't have ADSP2 in your SG-2020, you need to have it put in!

Great Rig  Time owned: 0 to 3 months
I saw this radio several years ago and wanted one and finally traded for a SG-2020ADSP, and wish I had got one earlier. I have had it for a month and have used it off and on during that time due to family duties,(new graddaughter, 2-sons in Iraq(I was a major couch potato during the war watching the news). Anyway the radio performs in my opinion better then some other radios of the same size. It does not have the VHF bands but I have several mobile and HT's for them. It was easy to find the menus and use the keys, but the best function is the ADSP(not the ADSP2). When you turn it on you can tell the difference, it works as good as what I have on some of my other rigs. I like the memories that come pre-installed except for one that and that is on 27mhz, but hey I can change it. I would and have recommended it to other hams looking for a small well made rade for portable/mobile and even for home use radio.

ASDP2  Time owned: more than 12 months
Just received my unit back from SGC with the new ASDP2 installed. Am not happy for these reasons, 1. with the ASDP2 on a cracking noise is heard in the speaker when a strong SSB signal is heard. It will only go away when the ASDP2 in turned off and 2. A loud hum is foung in the earphone when the ASDP2 is on making CW operation difficult. It will go away when the ASDP unit is off. SGC has agreed to take another look at the unit and it will be shipped back. I am hopeful I just have a bad unit and this is not standard.

Best I've ever used!  Time owned: 0 to 3 months
Ever since I saw the SG-2020, I have wanted it. It was my dream rig. But I read some reviews that said it wasn't all that great. Like a fool, I believed the hype, and didn't buy one when I had the chance.
Fast forward several years of waiting, and I finally got the SG-2020 ADSP. I chose to check it out myself. I could kick myself for not getting one sooner.
When I first tuned 30m, there was a signal buried way down. My wife and I couldn't copy him at all.
I narrowed the bandwidth, and kicked in the ADSP. Boom! As the 2m guys say "full quieting" it was almost scary how well we pulled this station out of the mud.
I primarily work CW with this rig, and have yet to plug in the mic. I may never use the mic because I am new to iambic keying, and I'm learning how to do that. So far, iambic is pretty cool, and the keyer in the radio is good.
The functions are fairly easy to memorize and are well placed. Single hand operation of the controls is possible and easy.
I really like this radio. I would reccomend it over any of the others in this class.

Don't Leave Home Without It  Time owned: more than 12 months
Great radio for portable and occasional mobile use. Also one of my favorites at home. Punchy Tx audio and good rcv audio. Very simple to operate (not burdened with excessive menu's). Excellent DSP. All around good little package that grows on you. Built tough, takes a lickin and keeps on tickin.

Well Done!  Time owned: 0 to 3 months
Excellent rig in a bulletproof package. I purchased the rig primarily for portable operation and it fits the application very well. Power consumption is relatively low, size and weight is perfect. Receiver is sensitive and selective, the DSP works great. Transmit audio is good and RX audio is fantastic. The controls and menus are easy to follow and the front panel is well thought out. The mechanical design and construction is as exceptional on the inside as it is on the outside. Customer service at SGC is exceptional!

The unit isn't loaded with bells and whistles but it is a solid performer in a really nice package. An excellent value that will last forever.

A great Rig1  Time owned: 3 to 6 months
I have worked with the SGC-2000's, and tuners overseas in very rough terrain. I have, over the years learned that SGC is here to stay and they make tough radios. So when the SG-2020 came out I watched for a while, not really wanting a radio without DSP. Then the SG-2020ADSP came out and I had to have one. It is a fun rig, is very tough, and works well. I get reports all the time that the VOGAD audio is punching right through the pile up, and they can't tell me from the 100watt rigs.
The DSP filter is fully adjustable and has almost "brickwall" skirts. Overall this is a great little rig, I find myself using it in the shack, instead of my other rigs, and I have lots of them! I purchased a third party backpack, added a 7.5 AH battery and what a "backpack" rig this is.
You'll love it, it's a well built little rig.
The microphone is a little "whimpy" -cheap-". I added an H-250 military handset to correct this little shortcoming. Not to worry about the "pigtail" connectors, they appear to be well built and should last fine. Go for it you won't be sorry, a great little fun rig!
