Clark...A filter more narrow that the 2.4kc first IF filter will not work in
that position unless you do some retuning of the basic rig. I purchased an
extra 9 Mhz 1.8kc filter and put it in my Omni 6. I thought it was working
great, but when I was doing the testing, I was only on 40 mtrs. Several days
later I tried to fire up full power output on 17mtrs and discovered max power
out was only 25 watts! I then checked all other bands including 80m. On 40m I
could get about 80 watts out, and all other bands only 25 watts out! When I
put
the original filter back into the first IF, everything returned to normal. I
didn't think the improvement was substantial enough to warranty changing my
Omni6 to a CW only xcrv.
By the way, I now have an FT1000MP that I'm now trying to learn how to set up
that 87-item menu and learn the function of those 90 buttons and knobs, then
I'm going to put my Omni back on the desk for some more a/b switching test. So
far, the MP is pretty impressive, it's the FIRST time that Yaesu has gotten
QSK
to work right over 30-40 wpm. I've been testing it up to 100 wpm and it does
great. Kind of a nightmare to have to set that complicated menu and then try
and figure out how to really make the thing work. Not like the TenTec
'plug-and-play' rigs!
