even further, lost RX,

TP3 next to VCO won't go below 4.5v needs to be 2.5v to lock the VCO
so any ideas why the voltage is so high ??
D1 is still ok :)

Re: 26 Mhz dipole antennas

just do a search on the net for any 11mtr 27mhz antennas then for 26mhz make the lengths a couple or three inch longer..

most 5/8th wave 27mhz antennas will SWR around 26.5 to 28mhz.. all below 1.1:5
