Once the WC is out of the shop, I’ve got to try the AN-101 antenna on the BC 654 to see if I can reach you guys. Poughkeepsie NY.

The PRC-108 is a twenty watt AM/USB transceiver that was built for the USCG by Sunair back in the seventies and although crystal control it uses the same crystal for both receive and transmit and has provisions for up to six channels.  I do not have the whip antenna but am planning on building up something with an eight foot whip that I have. The radio has an internal antenna tuner section that compensates for the short antenna and a convenient jumper on the front that allows you to use the 50 Ohm output direct or go thru its internal tuner.

Going to assume that the low dipole had no vertical component and no real ground wave to speak of and that was the problem. Think If I can get the short vertical antenna together it may be the solution to that sort of problem but cannot see a short vertical working for long range net operations.
> Another question would be once I get the vertical together assume that I can do the tuning by inserting a SWR meter between the RF Output and Antenna input to the tuner jack but in order to correctly tune the radio would I have to take it outside and do the antenna tuning in the clear or can I set it up in the shop and do the coil taps and all that sort of stuff there? The manual has a chart for setting what coil tap you use for the whip antenna but being I don’t have the factory whip going to assume it’s about useless.
