22 Meter Band HiFER Beacons / AA0RQ running fast
« on: March 21, 2017, 2245 UTC »
Heard in the later afternoon (0100 Z) on Sunday afternoon, AA0RQ with very speedy Morse, occasionally audible. None of the other neighbors in the 13,563.XXX kHz vicinity were coming through.

Lower down, I received USC and NC amongst the FSK beacons nearer 13,555 kHz. These reached ocasional audibility, solid copy using Spectrum Lab. Not much sign of anyone else.

One thing I am trying to do is find nearby signals (up to few 100 kHz away) that would make useful sources for a gauge comparison for HiFer propagation. Ideally, this would be a signal or signals nearly always audible a skip away. The aim is to track reception and correlate it with activity within the 22m ISM band. There is the 22m broadcast band - I may start there - and Volmet broadcasts amongst the 13 MHz ATC frequencies. Food for thought, as there are signals from Honolulu to the West, and New York to the East.


22 Meter Band HiFER Beacons / 17th March Listening
« on: March 17, 2017, 1653 UTC »
Brief listening session this morning (~0800 PST/ 1500z)

Using spectrum lab and the "random wire dipole" aerial, the FSK beacons NC, USC and EH in the narrow band around 13,555.xxx kHz came in strongly. Hints of another signal too, but I couldn't identify.

I listened for the regular Morse beacons in the higher portion of the band, but heard/saw nothing. Quite often they come up later in the day.



22 Meter Band HiFER Beacons / Re: Listening today

Thanks tesla!

I have often wondered about the propagation W-E versus E-W. Alas, there is no-one to my West to compare - we need a Hawaii HiFER! But I do receive good, often amazing signals from the Carolinas, Illinois, typically until late afternoon (Winter listening) then everything fades away. I'm not sure how the dawn and dusk differences  affect signals at this frequency - I guess I should read up on 20 m propagation for starters.


22 Meter Band HiFER Beacons / HiFer Operator Info - Discuss!
« on: March 14, 2017, 2258 UTC »
I thought it might be a good idea to have a thread for details of 22 m HiFer operators to share details, operating modes and schedules, and also their monitoring habits.

So to start of off, I run beacon PVC on 13,558.4 kHz from Northern California. Transmitter is a converted and attenuated QRP transmitter kit operated by a memory keyer sending at 5 WPM. The antenna is a sloping dipole with the centre about 20 ft above the house roof with the "legs" sloping downward, oriented approximately NorthWest-SouthEast.

For monitoring, I have a separate dipole at a quieter location in the garden. The beacon is de-activated whilst listening.



22 Meter Band HiFER Beacons / Weekend Listening 11&12 March 2017
« on: March 14, 2017, 2247 UTC »
From my QTH in Northern California, I spent time monitoring the 22 m band Typically ~18:00 UTC each day.

Logged using Spectrum Lab on the pc, connected to the receiver's audio line output, I detected NC (13,555.6~), USC (13,555.5) and MTI (13,557,530). in the  The former two use narrow FSK modes, all three operate at QRSS speeds.
During a later 12 March session (23:00Z) NC was audible as well as a strng trace via spectrum lab.

Conditions did not favour the commonly heard AZ, AA0RQ or GNK this time around.


Thanks for the report tesla. Always nice to know the signal is getting out.

I hope to do some listening this weekend. A little receiving antenna testing also.

Hi Folks,

Just thought I would add to this conversation, by way of an introduction.

I operate a HiFER beacon "PVC" on 13,558.4 kHz, in the San Francisco Bay Area, and monitor the 22 m band relatively frequently.

Recently (earlier this week) I took a small portable set around town with me, just to monitor the beacon signal whilst out walking. Even in a semi-rural area - houses and utility poles, no industry - there were quite a few spots where other signals sprang up, within +/- 2 kHz of the centre frequency of the receiver. These were often very localised - audible for perhaps a couple of hundred feet along the street and rapid dashes etc. where certainly amongst what was heard. By contrast, the beacon was audible except in a couple of descrete places. It is not often we can get up and walk around whilst listening, but in this band, it can be worthwhile to help discriminate signal types.

By the way, any reports of PVC would be most welcome.
