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.

Hi Dan, I am looking for CB-14, Comstat 19 pages. Would have that? Thanks, SL

Some variants of that amp, have the ability to turn the preamp on, when the power is off. Some don't.

I see a thing of beauty evolving before my tired eyes.

My 2 cents. NO SWITCHES!

Astatic or MFJ? Seriously? I wouldn't admit to that, in this forum of esteemed individuals :)

Check this out. Simple enough, but effective.
