[1000mp] Mark V Front-End Amp Setting.

[WX5L]

Hello,

I wanted to share this observation I recent made with my Mark V.

With a signal generator I injected the theorical s-9 signal level of -73
dbm. Indeed the s meter read s-9 on all bands. I've always set my receiver
front-end to "tuned" in menu 8-4 but as a curiosity test I switch to "flat"
and found a slight increase in sensitivity as indicated on the s-meter of
about 6 db. Not much really but could make the diffference under very weak
signal situations.

I would have thought in the 'tuned" setting and having seperate tuned
amplifiers for the low and high bands I would notice higher gain but that
was not the case.

This slight increase would probably be unnoticable with on-air copy due to
qsb ect but with a steady signal it was obvious.

This was not a sophisticated testing procedure and the results were contrary
to what I thought.

73,
Randy
