Re: Coupling a scope to transmitter output

["Wilson G. Hein" <wilson.hein@verizon.net>]

How about a simple pickup loop? Tak a piece of coax, on onme end put
your connector to go to the spec an, and on the other strip the coax
back enough to have enough of the insulated inner conductor to make 3 or
more loops, strip about 1/4 inch of insulation off of the end of the
center conductor and solder it back onto the shield where it goes back
into the outer insulator. Put the loop around the coax between the
transmitter and antenna. Should be satisfactory coupling to read the
tx'd signal.
