Reviews & stories

Good fun to listen to

Yaesu FRG-7700, Desktop Shortwave receiver

The FRG-7700 is not the best receiver to be had, but it performs quite okay for a rig more than 20 years old. I bought mine for about 75 euro's, which I think is great value. The optional memory module isn't installed in my rig. I also have the antenna tuner (FRT-7700), but I don't use it much.

Frequency stability is the biggest weakness in my opinion. In order to listen to a station (especially weak ones) you need to constantly keep tuning. If you don't you'll lose the station in minutes. Receiving digital modes is all but impossible because of this instability.

All in all the FRG-7700 is a basic rig which performs well considering its age. But its great fun to use and listen to!

Good quality SWL set.

Yaesu FRG-7700, Desktop Shortwave receiver

A really good, basic SWL set similar in design to the Kenwood R-1000. It almost requires a tuned antenna though, and in fact Yaesu made a complementary preselector-tuner for this radio. When used as such (just an indoor tuned loop is fine) the FRG-7700 really sings - you'll be in for an SWL joy ride. Good punchy audio, great stability, ease of use and fairly good filter selectivity on sideband (2.7 kHz). Its a desktop rig that doesn't do too much, but doesn't do too little, and delivers the goods in fine fashion.

I prefer the FRG-7700 over the:

- Kenwood R-1000
- Kenwood R-2000 (w/o VHF converter)
- Drake SW-8
- Yaesu FRG-8800

The FRG-7700 doesn't usually sell for a lot - it shouldn't - I'd say a perfect, unblemished version is worth $300, tops, not a penny more.
