Hi Brian,
I could wish that there was another CW operator within VHF range here :-) The MOVE II satellite beacon sounds likely as there was definitely Doppler (negative, it was moving away at 21:12) shift on it. But I appreciate the helpful speculation.

Another plausible idea is that someone was practicing CW on 145.948 and you happened to pick it up locally. Seems like an odd frequency to practice on however it cannot be ruled out

Hi Scott,
I tried to get an audio sample of the beacon, but no luck. After spending some time downloading a few files (long, slow download) identified as CW at the satnoggs site I had to give up, there was no identifiable Morse on the ones I downloaded.
So I can't say that it wasn't Move II, the CW was at about 25wpm, some longer dashes, it appeared to me to be random, definitely no audible data.
Too bad I didn't record it.

Good day, Ron!
Satellite 'Move-2' was west of your location around that time & is
supposed
to have a beacon on 145.950. So, that's a possible source.

back in the late 80's and early 90's I'd heard this on the HF sats that downlinked on 10M, but not on 2M.
While looking at future satellite plots I had the receiver tuned to the mid band of the AO7 downlink and I'm hearing CW (145.948 MHz). There are no amateur satellites above my horizon, anywhere. It was very clear, sounded like someone listening for their output, long dashes, bursts of CW, pauses, more of the same. I thought that I'd recorded it, but I didn't press the record button long enough and have nothing to show for it. GPredict, at about 21:12 UTC had the azimuth of AO7 at 327 deg with an elevation of -54. It lasted a few minutes and the followed the Doppler correction as shown on GPredict. When I pointed my antenna to the GPredict azimuth for AO7 the signal strength noticeably increased.
Does this also happen on 2M?
