One for the experts........today I re-checked my VCO voltage readings for
each band ( they were fine), but I realized that the table lists all bands
except the 160m band.
Unless I am wrong, there is nothing in the 160m module instructions to tell
you what VCO voltage to expect, so I tried a few readings there and was
quite surprised at how little voltage I actually had.
At 1800KHz I read only 0.61v and that rises to about 1.0v by about
1900KHz....still somewhat less than the 1.5v minimum suggested.
I can forget about the statement in the manual where it says" Receive-only
operation down to about 1.4MHZ is possible"......as my VCO drops to 0.0v at
1600KHz.
How does this compare with *your* K2 VCO readings?? My K2 is a pre-3000 set
with all the mods and up-grades to bring it up to latest series specs. It
is quite conceivable it is not "up to specs" on 160m :-( but it appears to
work fine there even with low VCO voltages!
