Good morning!
A new low power beacon, located in a western desert, will be tested
- starting on Thursday 6/24 at ~7:30pm pacific time (0230 UTC 6/25), and
- ending on Sunday 6/27 at ~1:00pm pacific time (2000 UTC 6/27).
Look for the beacon between 4100 and 4110 KHz, with a 1/2 second dash.
Please send reception reports to beaconpop@protonmail.com. Include the location of receiver and the beacon's period to get an e-QSL with more information about the beacon.
This is only a short 2.5 day test of the beacon TX, the site, and solar and antenna performance. If all goes well the beacon will be permanently emplaced and run 24/7 later this summer.
Many Thanks,
BPOP

As soon as it is running be sure to post a more exact frequency for us so we can positively ID it. I'm looking forward to hearing it!

Look for it at 4109.5

I have a slow dasher on 4109.43 about S5-S6 on the KFS SE kiwi
-
weak but readable on the Wrightwood, CA Kiwi http://ak7v.hopto.org:8073/

Not hearing it today on any SDRs. I sent an email to the provided address.

The only thing I heard was something on 4107.53 and it was... ummm.... rather ill for a beacon! :o
(long dash, the letter "S" and then into a suicidal waver and disappeared)

Excuse my ignorance but what is meant by a half second dash? On 4109.05 I hear a really bad brief kinda chuff noise once a minute or so is this what I'm looking for?

4109.05 is too low in frequency for the pop up beacon.
Think of Morse code’s dots and dashes withe the dot being a quick blip and a dash being three to four times longer.
Lots of good pirate beacon examples on YouTube under the name First Token who also a member on this forum.

It appears the pop-up beacon is no longer transmitting.
It started out nicely and was being heard in CA, UT, NV and even weakly in HI (!). But this morning only a few strong dashes were heard 5- 10 minutes apart - as if the 555 timer keying circuit malfunctioned. Nothing being heard now. There was a big rain and windstorm last night and maybe the enclosure leaked. The beacon will be retrieved and a post mortem will be performed.

I’m really sorry to hear of the short run but it’s been pretty hot lately.
I had one circuit board where there was a solder whisker that cold temps would cause it to make a short circuit and shut down a transmitter. Hot temps were not a problem.
Keep us posted!

The pop-up beacon was retrieved and debugged. Wish I had a better story, like a badger chewed the coax or the beacon was struck by ball lightning, or...? However, the reason the beacon stopped transmitting (after only 12 hours) was much more mundane: a bad solder joint in the 555 keying circuit.
The beacon has been fixed and tested. It will be re-deployed later this summer. One enhancement will be to replace the 555 circuit with an ATTiny85 keyer to send something other than a simple periodic dash.
Many thanks the listerners who managed to catch the beacon while it worked and sent reception reports.

When will you send out the e-QSLs?
I sent my request on the 25th.
Thanks!!
-
Sorry for the delay.. sent it as you were typing, I think!

I am hearing a very strong slow dasher on 4109.55 on the KFS omni Kiwi
Is it the Popup beacon back on the air?
-
The repaired beacon was on the air from the bpop test range for about 1 hour that morning. Good catch!
