I recently purchased the Corona RD820II with 10 crystals and hoped that it would contain the one crystal I need (35.100 freq #70). Unfortunately that crystal was not one of the 10.....I have no need for crystals #s 61,62,63,75,73,80,185,187 or 190......anyone have a #70 and wish to trade???

A surprisepack of ten different not specified ones. You may get lucky:) And if you are using a synth transmitter it doesn't matter.

14 thumbs up!
I also ordered the 35 Mhz one and got the exact frequency crystals as one another guy did. So I taught that it might help if I'll list the crystals I got:
Frequency: 40. -665, -675, -685, -690, -770, -715, -775, -815, -825, -985Mhz

When talking about the receiver itself, this is the best long range receiver I've ever had. All this regular PPM thing is crap, but this one seem to have even better renge than my PCM receiver Graupner SMC14

Great RX, interference does not exist anymore, it's full range rx, I use it on my glider Icefire II, I'm very very happy

Very good receiver, but be careful, in a cold day the receiver didn't work, I discovered that it was due to the cristal (at home I froze it with the spray to check). Changed the cristal and everything ok.

this is a glitch proof receiver, the crystal perhaps are not all suitable for european use, so take a look to the review because the freq list match exactly
