Hello everybody, as nobody wants to sell me the necessary crystals to clone the unobtanium FM board of my YAESU FT-920
, or do some other form of modulator/demodulator for 8.215MHz, I've decided fro another approach, and that is to add a "waterfall adapter" to the device, it has a nice tapping point on the first IF of 68,985MHz and I'll either plug it into my PC or put some RPi and just output the audio. I will have at least FM reception plus the other SDR goodies.
Now, I've got some early SDR sticks, even some that were claiming low freq front-end and they were mediocre at best under 100MHz, my question to the community is:
Is there a not too expensive modern device that could be used around 70MHz with good performance ?
Bonus points if is Linux supported, extra bonus points if available in EU.
EXTRA, SUPER, DOUBLE PLUS bonus points if someone could come or point me to a schematic for such module ( the FM mod/demod, not SDR) or 8.215MHz, doable with reasonably costing and available components. I will still install the SDR tap but I'll try to design a replacement FM board as well.
Thanks,
