22 Meter Band Beacons / Beacon PVC temporarily off
« on: Today at 00:54 »
Hi Folks,

Beacon PVC, 13,555.55~ is temporarily off air until storm damage to the antenna can be repaired. I'll update accordingly.

Cheers

22 Meter Band Beacons / Re: Beacon reception
« on: October 29, 2019, 1929 UTC »
Beacon PVC active here in California. 13,555.55 kHz. Often it is turned off at weekends so that I can listen without being swamped.

HF propagation isn't being kind to beacons much of the time at the moment. Do try for the hours before and after sunset, there can be a lift in conditions during this period of the day.

SWL,

A quick search turned up this Ofcom document:

https://www.ofcom.org.uk/__data/assets/pdf_file/0022/103297/fat-ism-frequencies.pdf

Alas, early on this states:

"In the United Kingdom the use of ISM apparatus is allowed provided it does not
contravene the provisions of the Wireless Telegraphy Act 2006. The International
Telecommunications Union defines ISM in the Radio Regulations as:
“industrial, scientific and medical (ISM) applications (of radio
frequency energy): Operation of equipment or appliances designed
to generate and use locally radio frequency energy for industrial,
scientific, medical, domestic or similar purposes, excluding
applications in the field of telecommunications.”

I found more of the same at this location for UK frequency allocation Again the Wireless and Telegraphy act is cited, but I have not had chance to try and decipher that particular document:

I suspect that any intentional radio emission with the intent of reaching significant distance is forbidden, but have yet to find proof.

22 Meter Band Beacons / PVC reaches Kansas!
« on: April 09, 2019, 1641 UTC »
Hi folks,

I received word that my beacon, PVC (13,555.5~~) was picked up by a LWCA member on 2nd and again on 3rd April, late in the afternoon in Kansas. That is a record distance of approximately 1400 miles for this station :)

Apparently there has been an indistinct trace visible several times at the same frequency, but this was the first occasion on which a positive ID could be made. You can read more at the LWCA website  https://www.lwca.net/mb/index.html, and if you are a member, there is a screenshot from Argo and a recording available.

I was just about to abandon the sloping dipole in favour of constructing a new 1/4 wave vertical antenna, but think I'll leave things as they are for a while longer.


Cheers

22 Meter Band Beacons / AZ heard Sunday 8:20 am (PST)
« on: February 04, 2019, 2156 UTC »
I had an unexpected early session at the listening desk yesterday(Sunday Feb 3rd). AZ (13,554.0~~ kHz) was making it to California quite audibly during the half hour after 8 am (PST). Inaudible, but detected via spectrogram, were NC and E H, operating in slow FSK mode as usual. One other feint trace may have been USC, but could not be read clearly.

Beacon PVC was temporarily disabled by a couple of power outages, but is currently in operation.

22 Meter Band Beacons / Re: Why "anonymous" beacons on 22 m?
« on: January 11, 2019, 2214 UTC »
That's a good point, Prariedog, I don't think anyone would know to put up a 22 m beacon without having encountered HFU or LWCA etc. - After all, why would one run a beacon without being able to know if it was received elsewhere?

On the other hand, some value privacy to a high degree.

PVC back on air!

22 Meter Band Beacons / PVC off temporarily
« on: November 29, 2018, 2121 UTC »
Hi Folks,

Had to remove connections to PVC's antenna today when thunder and lightning jolted me awake!

I'll restore operation ASAP.

The storms also dragged my long-wire aerial down again. That is the second time this week...

Cheers

Last week I brought the Lowe HF150 in to the office. It has a sensitive Hi Z active antenna input. Alongside a few carriers within ISM limits, was a massive broad-band hash from all the other equipment and lighting circuits. In fact this was plenty audible with the whip antenna switched to the straight 50 ohm input. I didn't get chance to monitor from outside the building.

One last thing - There was a nice clear dasher signal.. traced to the NFC/RFID transponder of my smart-phone!

That is an interesting supposition Exo.

Since I work at a manufacturing facility that uses RF generators, I could ask. It is also a perfect excuse to bring the portable listening setup to work :)

22 Meter Band Beacons / Re: 13 MHz Western USA Beacons
« on: November 09, 2018, 0243 UTC »
Nice report Exo. Over the weekend, I was able to copy AZ, and also a number of the beacons clustered around 13,555.xxx. The slower mode signals visualise nicely using Spectrum Lab in QRSS3 mode. I have a screenshot, but need to work out how to include it in a post...

22 Meter Band Beacons / Re: GNK 13564 1845 UTC 7 Oct 2018
« on: November 06, 2018, 2122 UTC »
Interesting, but they can't all be over power. GNK comes in fairly regularly - as it did for a while on the 4th Nov. But also signals from CT and NC, with similar or greater strength!

I could only wish for such reach for PVC!

That noise region certainly checks out here in Northern Calilfornia. I should bring a receiver to work - we have lots of tools with RF generators, I'll bet the ISM is a riot here in San Jose!

22 Meter Band Beacons / Re: HiFER "AN" 13563.0
« on: October 22, 2018, 2358 UTC »
According to a recent message on the LWCA message board, it is located in Somerton, AZ. A Black Cat Systems Kit operating into a Hamstick vertical mounted on a metal roof building. The system is solar powered.

I must listen out, the Arizona beacons are often audible copy here in Northern California.

Thanks for the report. However, this is not the present frequency for PVC. Keep trying :)
