30 July 2000
Activity was spread out over a number of days in July as I was unable to be around for the activity weekend of 21 & 22 July.
During July I decided to do some comparison tests between my existing RX pre amps and one from Charlie G3WDG. Unfortunately, I destroyed both my pre amps in the process by applying 12 volts to their 5 volt supply inputs.
A lot of time was spent doing repairs an attempting to match or better the previous performance of my system. Currently, I'm using an MGF4919 followed by an MGF1412-09. Performance seems to be marginally better than my old system.
I need to spend some more time setting benchmarks on performance of the current system so that I can make more accurate comparisons in the future.
