For the last day or so, I have been hearing morse code several times an hour on CDF Command 2. I am hearing it from SW Riverside county but I am thinking it is coming from MVU but I could be wrong. I have never heard morse code on a CDF Command channel in the past. Just wondering if anyone else is hearing it.

Morse Code on CDF Command 2

In my area on the AEU Local Net repeater, the CWID Morse code comes through the repeater as well. For whatever reason, the CWID is being sent with the PL tone of the repeater instead of just CSQ.
The repeater call sign in CW ID’s as KE6TLT/R
Is this an amateur radio call sign? FCC database shows it for someone out of Huntington Beach.
Yes, it is indeed an amateur radio call sign. (Orange County)
I've heard it too. It's definitely coming in via the repeater input. Not "official" sounding. Somebody oopsed.
Years ago, probably close to 10 or so, one of the CalFire repeaters was putting out amateur traffic - as I recall it was one of the more "racy" LA based 2 meter repeaters too so it certainly got noticed!
I could tell that there was another audio signal at lower volume mixed with the amateur traffic so I knew it was an intermod product.
I did some math and found the other signal that was mixing with the amateur signal to create the product landing right on the CalFire repeater input frequency. I can't recall whether the repeater had CSQ on the input or possibly the CTCSS protection was still getting "falsed" by the mixing product which probably included combo of the two interfering signals' CTCSS tones anyway.
The other signal was, if I recall correctly, some UHF business repeater.
Anywho, I posted about this on this forum and not too long thereafter the issue went away.
I need to dig around to find that old thread but, unless it was deleted, it should be here somewhere.
Of course this current issue may not be due to something similar but...??
Next time it happens, see if you can here another signals' audio at lower volume mixed in with the amateur signal - if you can here something like that it's a pretty sure thing that it's an intermod product.
Of course the other signal might not be analog so might be harder to discern if at very low level.

Found the old thread - it was back in 2010! And that was also on Command 2.
Thread is here for anyone interested: 147.435MHz intermod on CalFire CMD2.
