They have a GoFundMe to finance this project which, so far, has raised $100 towards a $20,000 goal.

I don't know. I'm not holding my breath.

Part 15 AM and FM Station Operation / Re: Part 15 AM and FM

Pinole Community Radio AM1610 on the air for 4 years 24/7 with Jazz, Blues, Vintage Country, Bluegrass, & Oldies. And of course all the important stuff that entails the city of Pinole, Ca. Our distance is pretty good with a Procaster.


I can testify that Pinole Community Radio has quite respectable coverage for a Part 15, and also sounds good. I drove through part of Pinole once, about a year ago, and was pleasantly surprised to be able to receive a listenable signal for the best part of a mile. The audio quality was good, the music mix very listenable, and distinctly different from everything else on the dial - either AM or FM.

This afternoon at 4:36pm local time (2336 utc), Windy is a little above the S4 - S5 noise level into a KiwiSDR in San Diego, courtesy of KA9Q. 98 degrees and 12.0V.

Also coming into a KiwiSDR in the Pahrump Valley in Southern Nevada at about the same signal level at the same time as the above report.

At roughly the same time (just a few minutes later), coming into a KiwiSDR in the Prescott Valley, AZ a little more weakly than the above 2 reports. Band noise of S3, and the beacon is at or a little below the level of the noise.

For a transmitter whose original intended purpose is simply to play recorded loops/announcements for realtors, and similar simple informational broadcasts, I can't say I'm too surprised. It suffices for that purpose and, being Part 15, is not subject to the audio bandwidth restrictions for licensed stations. Anyone who is keen to limit the audio bandwidth could put an LPF or BPF at the audio input. On the other hand, if you are not required to limit your audio bandwidth by law, why do so? I doubt there'd be a perceptible increase in range by doing so.

It would be nice to be able to get rid of some of the 60 cycle hum though.

That's in line with my general thoughts too, Token. My main HF antenna has been down for a few months, so online SDR's are my only choice. However, even when it was up, I am in a fairly noisy and less than ideal urban location. The KPH SDR is in roughly the same part of the world as me, so represents close to what I could hear if I had a better location and good antenna.

My thinking is that a reception report, whether from a local receiver, or online SDR, is a data point and, as such, is potentially useful. Important, as you say, to note the location of any online SDR being used.

Hexy 2K is coming in on 7600.5 at about S2 to the KPH SDR in Point Reyes, CA at 2115 utc.

I heard Windy send an S sometime around 1100 UTC 20 Apr 2020, I forget the exact time.

That's interesting. I'm probably missing something, but can't think of where an S would fit into Windy's telemetry. I just heard it on the KPH SDR, at 2346 utc. I haven't listened at this time of day before, and it was warmer than usual, at 81 degrees and 12.5V.

Good solid S6 into the KPH SDR in Point Reyes, Northern CA at 0603 utc (1103pm local time).

At 0555 utc, Windy is sending 62 degrees and 11.5V. Perfectly Q5 signal at about an S4 into the KPH SDR in Point Reyes, Northern CA.

Listening late at night, and Windy is coming in at about an S6 to the KPH SDR. 61 degrees and 11.6V.

Rocky coming in this morning at about an S2 on the KPH SDR in Point Reyes, CA. Chirpy, chirpy, cheep cheep! (That was part of the refrain from a British 1970's Top 40 hit. I don't expect anyone to get that. The Brit in me couldn't help it :) )

Noise level at about an S2 - S3 on the KPH SDR in Point Reyes, CA. Windy is about the same signal level and easily readable, except for the occasional fade below the noise. 75 degrees and 11.7V at 1618 utc.

Also, Hexy2K clearly readable with about an S1 signal and occasional fades at 1634 utc on 6700.5. A little bit of frequency drifting, which is OK with me. It gives it character :)  Over the few minutes I listened, the drift didn't sound like more than a few tens of Hz. It would drift off, then come back to where it was before. Quite charming, really!

With regard to your previous mention of using SDRs being "allowed" or not, I think they area a great tool and have been a huge help to me.

Thanks. That's my view too, as long as there is transparency in the report i.e. the poster states what SDR is being used. This way, the report is meaningful.

Am hearing what I assume is Rocky on the KPH SDR in Point Reyes, CA at about an S1 or S2 at 1830 utc. Fast dits (about 180/minute), with a chirp on the signal.

If my report using the KPH SDR is out of order, please advise. A little over S7 into Point Reyes, CA at 0720 utc. Telemetry was 11.8V and 60 degrees.
