The TG37 SSB sideband adapter is a perfect fit for the Redsun RP2000 and RP2100 radios. The CCRadioSW is Redsun RP2100, and this SSB adaptor provides the missing SSB decoding. Simply add 4 AA batteries and plug it in.
It has been very hard to find...until now.
Yesterday, May 13, 2010, I saw a Chinese seller had 10 of them for sale for $24.99...a very fair price. I immediately ordered one.
If you have a CCRadio SW, or one of it's Redsun variations, this is a nice addition to get.
