Title: Question A lite Mod for Swan series for a little better AM
Post by: ka3zlr on October 14, 2009, 09:37:33 AM
Good Morning,

Awhile back there was a small discussion on the forum on the bettering of Swans for AM somebody did
I think it was just bypassing the filter?

Is that what it is, what condensers were called for .1 .01 I forget I'd be much obliged for any help.

Either will work but you must remove the filter connections to bypass.

Thank You David I am much obliged, I have come into the careship of a 700 CX series and was wondering with a little work how it would sound on AM.

I have gotten good reports using my 700CX as is. I just unbalance the modulator and turn the mike gain down to approximately half that used for SSB. The signal, however is SSB with carrier not DSB with carrier as with a normal AM signal. I keep transmissions short and have a muffin fan blowing into the RF cage. The 6LB6 finals get a workout. :)
