    HTX-10 pll problem?

    btw, I will have a proper osc by 2 weeks I hope..so far using a TinySa I probed again the CPU pin 1, I see 4.5 MhZ at 2.30 Volts. the HTX10 service manuals indicates that voltage is correct. And Im not getting any signal from the 10.695 crystal..So how about D30 the VCO coil's varactor? what...

    HTX-10 pll problem?

    the RX side is fine. I can hear stations when I adjust the VCO coil and I injected a 28.00 signal through the antenna port and does +30 on the RF scale..I used a TinySa..
