Perfect for portable HF……. The SG-2020 covers all HF frequencies from 1.8 to 30 Mhz. It is factory-set for 20 watts PEP with front panel power adjustments down to 1W using USB or LSB. There are 20 factory pre-programmed memories preset to frequencies within each of the nine amateur bands for fast band accessibility. Each memory position can be selected for a specific transmitter output power, specific amount of bandwidth filtering, mode and split VFO. The memory channels can be re-programmed to accommodate alternate frequencies of your choice within the frequency range and a simple unlock procedure allows you to choose any HF frequency worldwide. This radio has a factory installed ADSP2 noise-canceling module. The ADSP2 was the last revision. SG-2020 radios with the ADSP2 are very hard to find. Radio comes with original handheld microphone, original manual, factory box, front pedestal stand and rubber protection grommet. It is very clean in collector grade condition. You dont see too many SG-2020s like this. Radio seems to be working well other than the BFO issue. However I did not test it thoroughly because there is a learning curve to operate it. Thus it is offered as-is for repair or parts. The item “SGC SG-2020 HF SSB & CW Transceiver 160-10m ADSP2 Installed, Very Clean” is in sale since Sunday, October 31, 2021.

This transceiver is in good physical condition with only a few scratches and receives great. However, it does have some transmitting issues. First, on SSB it transmits fine below 21MHz, however the power drops off above that. Second, we get practically no power out on CW. Could this be because of specialized programming? It may need work. The radio comes with it’s original SG-5226 hand mic and packaging! If you are not familiar with this radio, we strongly advise that you download the manual and read it before attempting to operate.

SGC MODEL SG-2020 SSB/CW 160-10 METER QRP TRANSCEIVER. We found this radio still packaged, I do not believe that he had the opportunity to use this and he has the exact same one still mounted in his truck and I do not know why he has two of these. I found a 12v cable to try it out (which I will include) I connected a short wire antenna to it and was listening to South Carolina loud and clear. It comes with the microphone but we could not find any paperwork for this. According to the box you can download the manual on line. There are no marks at all on the radio and I do not think he ever used it as the mic was still wrapped in its plastic. Note: the output antenna connector has a slight downward angle to it (does not affect using connector). This is the transceiver for base, backpack or business trips – the ultimate portable trasceiver. There are no confusing menus and just two-step operation: select your frequency and transmit.
