Re: [softrock40] Re: Softrock V6.1 TXRX
- Hi all,
I changed the Two Resistors on the Input from the souncard from 10K to 4K7 (R3 & R9).
I changedR56 for a 15K.
Now get over a Watt out on 40/30 Meters, only trouble is I cant seem to get more than 10 watts from the Linear ATM on 30 Meters.
Anyway I seem to have a prob with my Antenna on 30 M, so next job is to sort that.
I will see what I can work on the 10 Watts....as long as OFCOMM don't turn up with their Spectrum Analyzer !!!! (Again!!!!!)
73s and thanks for all the help,

Hi Peter, Tony's comment answers the question, but I can confirm that
I am using the values he recomends, plus the lowered value of R3 and
R9 feeding the QSE preamp. Incidentally Andre Adrians circuit is the
2xIRF510 version, I got confused! John G0UCP
