I've had a few of these. One or two of them drifted slightly until 'warmup', the others didn't drift at all. I just thought that was interesting. But for flat-out utility Dx'ing I believe the FRG-100 is about as good as it can possibly get. Nice slimline appearance too, ala the Lowe receivers, but the FRG-100 has a slew of features that aren't immediately obvious upon looking at it. The famous Drake R-8 had stronger audio, but in no way was it better in catching the weak stuff. In fact the FRG-100 is better. I see now that the used price has gone way up for these, to around $450. Still worth it, all things told.
Excelent receiver. Sensitivity and Rejection is superb.
High performance radio. Easy to use with the features that you need. 50khz to 30Mhz.
High quality and performance. Great features and excelent reception.
Excelent receiver, easy to use and high performance.
So easy to use - Just plug and go... Works amazingly well with just 50 feet horizontal wire at 25 feet at the feed point and fed with coax and earthed via a lightning conductor to a 4 feet long earth spike in the ground. Low noise floor and attenuator works well if the amateur bands are busy. Excellent on broadcast stations and maritime. On a par with the Drake SW8 - 10/10...
I've owned a frog-100 for several months now and I notice that it has excellent low noise floor. Much more than my r-75. Also has agc that works quite well. And has extremely high sensitivity. It's a keeper.
