IF amp. 9MHz - single ad600 working in sequential mode, AGC realized
with AD8307 and opamp (http://www.mydarc.de/dc4ku/S_Meter.pdf -
control voltage for AGC realized with TL431 similar to cdg2000.
1. - find a simplest way to make manual IF control. ("manual" does
NOT mean turning off AGC but possibility to change amplification)
Change a control voltage? add a manual regulated stage???
2. changinge a time constant of AGC
Any directions or ideas?
