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...

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

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?

Strange swr behavior resolved. Galaxy 2547 dead key .75 watts 4 tube 6jb6 driving x-force 10 pill. Anytime I turned the dead key up past a 200 watt my swr would go from 1.2 steady to bouncing erratically all the way to 3. Some research pointed me toward a bad connection on my coax or arching...

Considering building a 5/8 wave ground plane for my base. If using a gamma match to feed a ground plane antenna would the radials and verticals be electrically common?

My L6 lightning quad is mounted on a hazer with non conductive wheels. How critical is it to have a direct ground connection to the boom?

I have a amp to power. Does the Mean Well LRS-600-12 cause any receive interference?

Anyone know much about a Sark 100? I have one that shows a output frequency 40.010 when it is actually 27.205. If anyone knows how to correct this I’d like to know.

Which works better at preventing common mode currents on outside of coax? Ferrite beads or wound toroid?

Some analyzers require 1/2 wavelength coax jumpers to display accurate results. So I’d like opinions around using solely 1/2 wavelength jumpers between meters,amps,drivers and radio. 1/2 wavelength multiples to antenna feed. Wouldn’t that insure your equipment will display more accurate readings...

Anyone know if this is correct Mods for this particular power supply? Any input is appreciated.
