QAnon / GOP Republicans mentally lack the necessary intelligence to even tell a decent lie (Ex: A cabal of Satanic, cannibalistic pedophiles run a global child sex trafficking ring and conspired against former President Dotard dRUMPf during his term in office... Jewish space lasers, etc.). What in the hell makes anyone believe these melon heads can actually govern?
Hi Steve,
That's a cool pan adapter! But, I'm wondering how it deals with receiver AGC. If the frontend is affected by AGC, stronger signals that make it thru the IF filters to the AGC detector will "pump the frontend gain downward", causing all displayed pips to follow. That's what I've noticed when looking at the 8.83 MHz IF wideband output of my various Kenmore rigs (TS-120S, TS-130S, TS-850S). I picked and buffered the IF of the two older rigs ahead of the IF filter; the '850 had it built-in (a second 8.83 MHz output from the "noise blanker mixer").
I imagine a Variable Gain Amplifier setup as an expander (derived from the RX AGC voltage) would do the trick. A pair of VGAs such as AD602 ICs would have plenty of dynamic range. Your thoughts?

An afterthought... I s'pose the expansion doesn't need to be hardware. It could be done in software, with an A/D input from the rig's AGC line.

Maybe, but I haven't seen it yet, and I've sold more then 100 of them, and it has not been mentioned. That said, if this were to occur, would it really matter? It's a Panadapter for less than $100. I have one customer who says my Panadapter blows his $1000 DMU-2000 away. Another who says my panadapter is much better then the LP=Pan set-up it replaced.
