Ifr 1000 Service Manual
Ifr 6000 Service Manual
Drjim, officially the only difference between the A and S versions just the 2 extra pc boards for the spectrum analyzer. While I allude to the missing page in the vco tune-up section of the Army manual, there is no details in IFR's own manuals. I suspect they figured you would send it in to them for service. My main problem was the SA dropped set when the unit fell out of the truck a week ago. All other functions were ok. Only 2 of the 6 SA board 1 adjustments (min-dispersion/max-dispersion) are called out in the adjustment procedures, not the offset and log adjustments. In the 1100S which is almost a copy of the 1000s they redesigned the card removing the offset/log adjustments.
I have been playing with the GRM114/GRM114A versions of the manual and while some components have changed numbering, they have not changed location. Almost got it. Used to V7A's at 140 and 150mhz and my hh at 145mhz to put 3 markers on the display and tweek. I just can't get the center freq in the center with the 2 ends on screen at the same time.
