Just keep in mind that this is checking the calibration of the duplex modulation against the units receive audio calibration. I would suggest checking the units rec calibration first. Put unit in GEN mode (yes, gen mode), dial 905.8 on var tone, spec analyzer in 1khz div, and watch for the 2nd dip on analyzer to null as you rotate the var gen....This should be exactly 5khz. Now you can do the modulation check on this video to check the duplex modulation calibration once you know the units FM rec audio is in cal....KG Electronics
Great video.I also have one of these but mine shows nothing on the display in generate mode but works well in duplex mode as in your video.Would love to have working any ideas would be appreciated.Thanks !
Is there a way to tell the option on a 1200s unit with just the serial numbers? I have a couple of units with the following serial numbers below.. Any help would be appreciated. Thank's Serial# 11150 Serial# 11017

I want to buy a source of this instrument that the source of mine burned can you help me? I live here in Brazil
Can you or anyone out there tell me how much the IFR 1200S cost when new?
Hello we have a unit that we are selling so we could buy Christmas presents for our kids and grand children too, please let us know !!!
Do you set DUP or DUP GEN mode? Reading the operator manual in DUP GEN mode the generated signal should not present at the DUPLEX connector
Yeah, I was saying, "Duplex", generate. Not "Duplex Generate". I should have said, "Set to generate a signal using the Duplex mode", or something.

jtridexter the digital voltmeter (Option10) is standard equipment on units with serial numbers 9267 and p (page 5-4 of the users manual)
.2ppm freq standard. Serial numbers above 5411
Battery - serial number above 5561
