Hi Steve, thanks you for replying to all my questions, pictures and schematics.
I have a heathkit vf1 and viking 122 vfo, will it work on my northern radio marine transceiver?
and do you know what the antenna output impedance is, can i just hook a long wire or do i need an antenna tuner, i wonder what type of antenna they used on board the ships.
Peter...It has been a while since this thread was active...I am working on my N529E S/N 143 right now...I have it on the air on 160 and 75 meters....The ideal antenna impedance is 50-60 ohms and the TX will tune there without the use of the internal antenna matching circuit(s) I don't see why a VFO wont work if you plug it into the Xtal socket...I wouldn't be afraid to try.. Have you got your TX working yet?? Good Luck...Steve KL7OF
