I am unable to locate the schematic, or internal photo, of the M+2/U that uses ONE DARLINGTON transistor. I found the schematic of the version that uses two discrete devices. That is NOT what I am in need of. The unit I have, uses a single 2N5306 device, for amplification. Thanks, SL

The glue, always gets the mic element in those

You are right, there is enough factory C, if the radio goes that low. I think you will figure it out. Overkill's was simple but effective. The Brazil guy that's hooked up with Troy, is awesome but impractical and just vaporware. Looks like you are in the middle, which seems like a good place...

Umm.....nope.

Thanks Dan. Not sure what happened with that one. The resolution is low and gets blurred when zooming in, particularly the schematic. SL

Hello Dan, I am looking for CB-82, TRC-9A/TRC-11. Thanks, SL

Thank you again Dan!

I hate to rain on your parade, but that overkill mod, is simple enough for most people. The 980SSB is locked down hard, so something is better than nothing. I really like what that guy did with his mod. In respect to VCO range, there may be something one could do, with a different varactor...

Talk is cheap. :)

Rule of thumb here, is fT x 2 of design frequency. The amp is $100. Buy one and make it work, then share your mods and results. SL

Hi Dan, I am in need of the CB-38 Dyna-Com 12A pages. Thanks, SL

Then build it. I wish you luck!

Slowly? :)

I think your efficiency numbers are exaggerated. A roof mounted hamstick is about 10% at 3.5 MHz. The numbers change dramatically, with height above ground, vs. frequency. SL

Just about every Icom HF radio PA uses them.

I have run hamsticks, with great success. The worst antenna I have tried, is a Chinese ripoff of the outbacker from Opek. Also, as far as I can recall, that antenna made by Henry Allen, was not a motorized screwdriver. He made the Texas Bugcatcher antennas. The best screwdriver I have...

I have two of these that preamp works with power off. One is the DSS, the other is Firebird. Both have two DPDT relays.

Hi Dan, I did search, but found nothing, so thanks for sending it. SL

Bollocks!

What you are saying in regard to device tabs, being band specific, is just not the case. 2SC2097, 2SC2904 are examples of this configuration.
