1. [Amps] How to tune an FL-2100B (score: 1): Author: Dan Wright <dwright12@neb.rr.com>; Date: Tue, 04 Jul 2006 06:02:19 -0500; Greetings!! I am new to this list, but not too awfully new to amateur radio, been licensed 42 years....but maybe that don't mean much! I have a recently acquired Yaesu FL-2100B. I have never owned on; /archives//html/Amps/2006-07/msg00170.html (7,136 bytes)

Since the PEP for normal 100% sine-wave modulated AM is 4 times the carrier power, and the FT101 can distort the audio and make it eight times or more the carrier, it easily could; /archives//html/Amps/2006-07/msg00172.html (9,102 bytes)

Why can't I just reduce the drive on the '101 to 25 watts and drive the amp with that? From brief experience: It looks like if I driv; /archives//html/Amps/2006-07/msg00180.html (8,071 bytes)

That's 100 watts PEP if you watch the peak envelope power and use the controls properly to maintain that peak level. You'd need a good PEP reading meter. The Ameritron PEP meter is; /archives//html/Amps/2006-07/msg00186.html (9,329 bytes)

Re: [Amps] How to tune an FL-2100B (score: 1): Author: R L Measures <r@somis.org>; Date: Tue, 4 Jul 2006 07:09:07 -0700; An arcing bandswitch in a 2100B is usually the result of regeneration roughly 95MHz. If you want to see the resonance that supports this phenomenon, pull the power plug and couple a dip-meter to eith; /archives//html/Amps/2006-07/msg00200.html (9,390 bytes)

Re: [Amps] How to tune an FL-2100B (score: 1): Author: R L Measures <r@somis.org>; Date: Tue, 4 Jul 2006 07:18:30 -0700; Another approach is to add an RF-NFB (neg, feedback) R in series with the cathode coupling cap. OTOH, Tom, an FL-2100B will do 600w PEP with voice modulation, and that might be enough to do 150w of c; /archives//html/Amps/2006-07/msg00201.html (10,324 bytes)
