Jim,
The component
came in that I need to try John’s last circuit change. Once I put
this paper behind me I’ll get them installed and see what happens.

Passband at -1 dB and -60 dB
I have some thoughts on this (ripple), after some
research I did late last night.
More later.

All,
I re-ran the -1 dB passband test of the 70 cm receiver
for my presentation.
Here’s another look at a 500 kHz span at 0.5
dB/Div:
Here’s a look at the -60 dB passband with a 2
MHz span and 5 dB/div. I increased the input
Level to get the skirts out of the noise.
It’s 1.248 MHz wide at -60 dBc.
