22 Meter Band HiFER Beacons / PCO loud and clear 13563.55 Khz
« on: December 10, 2017, 0400 UTC »
There seemed to be good conditions today for reception here in Calif. PCO faded up to easy readibility a few times around 1520 PST.. GNK was in the mix, and a few signals around the 13.555 zone including USC and WM

My apologies... I meant PCO. Definitely heard, at different tone from other signals and at your frequency (trace observed using Spectrum Lab), but I was not able to catch/decipher a full ID.

Sorry for the mix-up

Monitoring yesterday, I heard solid copy from RQ, RF and GNK, around 2100 UTC (Afternoon Pacific Time). No need for Spectrum Lab :)

RF was coming in to California nicely yesterday afternoon, several IDs plainly audible between fade. Time was around 1900UTC. Nice clean signal, by the way, no hint of roughness as I'd previously thought.

That loop should work well, Chris.

I tested a poorly mounted 4' x 4' square tuned loop on receive and obtained good copy of 22m beacons. It was a quick build with pvc pipe, a 150 pf ceramic trimmer at the top, and a small coupling loop at the bottom, no active electronics. I'm actually considering an experiment with this, or a similar antenna, for transmitting PVC.

Thanks for the information Ed H! I've downloaded the Spectrum Lab and will have to study up a bit on the Help section to see if I can get it working properly. Yes, I have a direct patch from the Old analog NRD-515 to my PC. I regularly use Shazam, MMSSTV, and record using Audacity.

Great! sounds like you are all set. There can be lots of fun stuff to dig out if you have patience for the slower modes :).

A very good place to start is the list kept (and maintained up to date) at LWCA: http://lwca.org/sitepage/part15/index.htm. You might have to click on the MedFER/HiFER button at the bottom of the page.

It would be nice to start another list here, as there are some operators and listeners not represented on LWCA.

Cheers

Well said tesla,

It is great to see reports, and learn the when and where of our beacons' coverage

Please listen, log, and let us know who you heard and when you heard them :)

Skipmuck - can you connect the receiver audio to a computer?

If so, there are some great free programs - I use Spectrum Lab, a spectrum analyser application - that provide a visual of the signal. You can enter the VFO setting from the receiver and determine the signal frequency very accurately. Another benefit is that you can use the program to "see" signals that you can't hear, and run slow traces to visualise the slow modes that some beacons use.

Heard here in CA on 21st Nov. A strong signal, good enough to be copied by ear. As reported on LWCA.

Nice to have a new beacon on the band - welcome Finman

Thanks tesla - always nice to get a report!

Limited listening here but last weekend AZ faded up to a good loud signal for a few minutes ~ 4pm local time (~1100Z)

First logging of this reliable catch for a long time. Let's hope for improving conditions.

PVC is still operational with the same 1/2 wave sloping dipole on the house roof. Walking checks indicate the same readability signals at ~ 1 mile distant.

22 Meter Band HiFER Beacons / Re: Poor conditions, interference
« on: August 29, 2017, 2328 UTC »
I think most of the problem is conditions. Interference is sporadic enough in nature here that beacons have a chance if one is patient. I've had rather little time to listen of late, so have not been following any trends in propagation. This weekend should allow some time for radio.

Also need to do some aerial checks on PVC - preventative maintenance etc.

Good news tesla.

I tried listening this weekend, but conditions and interference were not conducive.

My Bad.... this signal is CODAR.

Which means at times I have another more rapid "buzzer" like interference which is something else.
