I have for sale Watkins-Johnson WJ-8770 MF-HF REceiver all mode.
I tested it from 100KHz to 30MHz because my generator wouldn't go any lower. Has superb selectivity and sensetivity. Still can hear a signal present as low as -120dBm. Portable 24VDC operation. Be happy to send some pics if you are interested. This is a high end high performance Government Radio.
Looking for best offer. Also have VHF Model all modes much similar WJ-8640.
Please send me questions vi email at: galiaf1@yahoo.com
