hello all,

And nice meet some or you on the air. I will like show the 20v3 progress and thanks for all the replies.
The transmitter is working on its am broadcast frequency of 1450 it puts out 1100 watts into dummy load.

I am thinking mono band 80 meter cw & am mode. I was also thinking 20 40 80 tri band ? let me here your thoughts Cool
Also can I get some ideas on the audio chain.

let me here what your thinking,

Not sure if the 20V3 will go to 20 or not.I know they work fine on 160 and 75.

Hi Steve,

You may want to contact Bill Carnes - N7OTQ of the Collins Collector Association.  He converted a 20V3 to operate on 75M.  Bill is a very competent engineer and I am sure would give you some pointers on how he did his.

That's a very nice rig! Beware the long RF wires of such big stuff. I learned the hard way what is designed spaciously like BC set has built in 'parasitic tuned circuits'.

You might want to contact Don K4KYV about running CW on AM rigs. He had a nice article about this very thing in a recent Electric Radio Magazine, either this month's or the month prior, if I'm not mistaken. Be forewarned that it is not all that simple to run CW on some BCB txs'. I can't speak for all of them.
