Thanks. I have this manual, maybe my issue with it wasn't fully understood. Look at the picture attached. The sark is showing the test frequency is 40.810 mhz. Connected to a frequency counter it is actually putting out 27.206 mhz. they should match. Right?

Does anyone know how to calibrate the test frequency to match the display frequency on this cheap analyzer?

I have a x-force straight 10 pill converted to HG 2879 it seems to have a 2 pill section that falls off after it warms up. Not excessive heat. It looks like it has cheep 104 feed back caps. If one of them falls out of tolerance when warmed up will that cause that section to fall off? If so what...

I’m 100% sure it’s is a knock off. It has really good reviews. Just looking for someone who has used the specific eightwood brand. I have ordered 40 ft of it to make up some jumpers. Have them made and installed. They seem. To have great shielding. Really good heat resistance as well.

Yeah I seen a BBI review on RG400. Not sure the brand he was referring to. I was gonna replace all my jumpers in the shack. His YouTube shows the way he installs the pl259 ends as well. Thanks 73’s

Has anyone used this coax? Is it good quality? https://a.co/d/0bCnVeb1 This is a Amazon link.

On the out put transformers that is.

What value metal clads are standard for HG 2sc2879 16D08. My box had Toshiba in it before and had 1000 pf. Should they be a different value? Like 1200pf.

Those are better than gold nuggets.

Copy that. I’d just trying to work out a way to know if all that combination is correct by testing.

I managed to get this job completed. Photos is completed results. Turns out I was chasing a bad coax and meter. Go figure. Probably what popped the pills originally. But my goal is to understand how to do input/output tuning. On amplifiers of this design.

It’s a XForce straight 10 pill. That burned completely up. I replaced all the pills from Toshiba 2879 red dot with hg 2879 16DO8 matched. Tested all the caps replaced one bad one on an output transformer. New mini coax, new 5 Port combiners/splitters. All new resistors throughout. All matched. I...

Anyone have a good reliable smith chart program download link? And some expertise on input output tuning amplifier. Can you use an antenna tuner on the amplifier input to verify 50ml input? Amp on and manually key the amp?

Wouldn’t the SWR swinging still be happening while running the tube type by itself?
