Among many other reasons, even ultra narrow band FM takes up too much spectrum space. 73 - Mac, K2GKK/5 Since 30 Nov 1953 Oklahoma City, OK USAF (Retired) 61-81 FAA (Retired) 94-10

FM greatly reduces noise on received signals. However there is a factor called "capture effect" with FM where the strongest signal will "capture" a receiver almost totally. As Dallas noted, if there a

I concur that this apparent initial spike is probably limited by ALC to a value that will NOT cause a problem since it is a momentary (and safe) level. An unreal problem in search of a solution, indee

What, exactly, is the ISSUE? Virtually all current SSB/CW rigs specify that AM carrier should be set at approximately 1/4 of the SSB PEP rating. 100% AM modulation of a 25 Watt carrier develops 100 Wa

It would appear to me that there are many "smoked" components on that board. Putting the loose item back in will not likely repair any problem! 73 de Mac, K2GKK/5 Since 30 Nov 1953 Oklahoma City, OK U

At one time, you could buy a complete IC-7000 control head from Icom, but that was quite a long time ago. I believe the cost for it was over $400. I bought an IC-7000 on eBay several years ago that ca

I am not familiar with the ATAS-100 antenna. Is it a version of a "screwdriver" antenna? If so, the TurboTuner-2 should work just fine with the IC-7000. I just bought one to use with my IC-706 Mk II.

I consider it mandatory for EVERY transmitter at a Field Day site use the appropriate bandpass filter at all times. Mr Sherwood will tell you that almost every transmitter or transceiver has broadband

No Aluminum Oxidation! I've assembled Mosley (and other) antennas using the Noalox and Penetrox for years (since 1963). They disassemble and reassemble easily, even after many years in the air! I beli

I am reasonably sure that DX Engineering also carries it or at least a substitute. You can also get it from Mosley antennas as they specify it for their antennas. 73 de Mac, K2GKK/5​ Since 30 Nov 1953

Heh, heh! Yep, but an IC-7000 is an awfully expensive FM broadcast receiver! 😉 I never use the 7000 for 2m/70cm. That's what my 2710, 2720, and 2730 are for! It's going to be interesting to learn what

Wide is normal almost everywhere. This is what is referred to as 5 kHz deviation with 15 kHz channel spacing. The NBFM mode is half or less than that. 15 kHz channel spacing is used in many locations,

I certainly concur with the possibility of too high overall deviation as outlined below by Paul Hansen! Excessive peak deviation can totally eliminate the "carrier" and cause squelch dropout. The same

I have searched both my owner and service manuals for the IC-7000. I have not yet found any adjustment for transmitted tone level. I suggest you contact Scott Malcolm at Malcolm Technical Support to s

Another owner has commented about this. His finding was that the transmit audio needs to be opened up at the low end to allow the so-called "sub-audible" tones to pass. I seem to remember that the low

Simply set the allowed frequencies in memories. I suggest using 61, 62, 63, 64, and 65. 73 de Mac, K2GKK/5​ Since 30 Nov 1953​ Oklahoma City, OK​ USAF, Retired ('61-'81)​ FAA, Retired ('94-'10)​
