22 Meter Band HiFER 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 HiFER Beacons / Re: HiFER "AN" 13563.0

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 :)

65
You are welcome to discuss the frequency pulling question on this thread. It is all connected :)

I moved PVC to a new temporary frequency using the generator. It is a simple switch press on the transmitter to go back to the crystal at 13,558.4 kHz

Prizes for correct answers to "What frequency is PVC on today"

Cheers

Thanks again for the feedback everyone.

Exo - your pic did not appear the first time I came back to the thread, but that is a great illustration, and very similar to what I experience along with others.

I also posted this at the LWCA message board, and I'll share what comes back.

Cheers,

Ed

I would expect the band centre to have the most issues... Equipment using this frequency is likely crystal controlled, and 13.56 crystals are likely to be relatively well clustered around centre.

I'm considering moving my beacon frequency, but need to implement a different frequency source than the crystal which has limited pull range. It's worth figuring out what the better spots will be in the band.

Using web SDR is a great idea to do some surveying myself. Not so many of the ones I have found provide full HF coverage, but a few allow reception of 22 m.

Thanks

Hi Folks,
It occurred to me that it would be a good idea to share the quietest listening spots in the 13553-13567 ISM allocation we know and love as the HiFER band.

My reasoning for this is more or less obvious - Where is a good spot to put one's beacon, if trying to reach a particular area?

For my QTH in the SF bay area, the only spot with consistent interference is 13560 - 13562 (as tuned in USB with a typical 2.2 kHz filter). Ergo, I can easily listen from the lower portion of the band, up to about 13,559 before whistles and bleeps interfere with hearing, or the AGC kicks into action. Using a Spectrum Lab, this can be pushed a little further. On the high side, 13,562 kHz up is all quiet.

I would be interested to hear from other beaconeers on their local conditions.

Cheers

Ed

I'll listen out when next at the radio bench.

Also have some nice printed QSL's for my beacon (PVC), and would be overjoyed to receive a report and send one off in the mail.

Cheers

22 Meter Band HiFER Beacons / Re: Signals to Correlate with 22m beacons.
« on: September 04, 2018, 2036 UTC »
Well, I started trying to correlate anyway - this is as much empirical investigation as anything else. The 13845 kHz signal is there much of the day, and on Saturday, moved from S3-5 with deep fades up to S5-7. Beacon observations seemed to track this single point observation, but more samples will build the picture.

The project continues, and I'll start to compare the 20 m beacons as well - there are plenty of receivers available :)

71
Great info, thanks Exo.

I'm aware of the 20 m beacons, and need to spend a bit more time observing them - good reminder!

The reason for looking at broadcast signals is to have something that is more continuous in nature, and would perhaps provide signals strong enough to record an S meter reading.

Anyway, I appreciate the response and ideas for other things to track.

Cheers

Hi Folks,

One thing I have been attempting to pursue is finding a predictor/barometer for propagation at 22 m. Helpfully, there is a broadcast band nearby, and SW.info indicates that there are some potentially helpful signals:

13,840 - Radio New Zealand International
13,845 - WWCR University Network, based in Nashville USA

Ideally, schedules should line up with beacon listening, so that reception of beacons and broadcast can be compared. Has anyone else tried this approach?

Regards,

Ed

22 Meter Band HiFER Beacons / Re: 13 MHz Western USA Beacons
« on: August 27, 2018, 1800 UTC »
Another Northern California listener here on the SF Peninsula. I also copied AZ by ear, local afternoon ~1500 PST (+DST), over the course of about 1 hour.

I was pleased to hear this signal, as it had not made it here for quite some time.

22 Meter Band HiFER Beacons / Re: 2nd June HiFER report
« on: August 02, 2018, 2157 UTC »
Interesting indeed FFZ. I'll often make a note of traces seen at known beacon frequencies, but I don't count these as definative loggings without a positive ID (or enough fragments over several repeats from which an ID can be assembled).

Regards,

Ed

22 Meter Band HiFER Beacons / 2nd June HiFER report
« on: June 08, 2018, 1842 UTC »
I found time to switch on and listen for a while on 2nd June (Around 030 UTC) and was rewarded with quite good conditions. Observations were aided by the use of Spectrum Lab.

In the higher portion of the band, EPA provided a strong trace, along with a hint of BUH (or perhaps BUZ) Both are new to the log here. A trace corresponded to RF, another to KC7MMI, and GNK appeared for a while.

Lower down, I Caught PBJ, TON and a hint of trace from a possible PLM.

Below this, EH was plainly audible, and an easy trace to read. Neighbor SIW was visible below, and USC above.

Quite the best conditions we have had here for some time.

Ed
