HF Beacons / Re: 4096.15 KHz New telemetry Beacon "L
« on: June 15, 2021, 1659 UTC »
I was thinking the same thing, it says BEACON L, so maybe its name should be L.

I noticed this beacon yesterday, but I have no idea how long it has been active, yesterday was literally the first day I have looked at this freq area in more than a week.


I've been logging data every day from a couple of beacons this month (except on the 5th) and always have the panadaptor on. "L" has a big signal that really sticks out so I'm going with yesterday as the launch. Unless someone PM's me with some "rumors" about deployment (and tech details).      8)

A few observations. The battery has only moved up by a tenth of a volt this morning so must be a small AH solar panel and "large" AH  battery. Temps seem to indicate a desert-ish area. Reading temp in Celsius without tenths of a degree seems a bit coarse compared to reading in Fahrenheit.

I've added this new L beacon to the master list. Congratulations to the creator for launching something new!

Maybe I got things wrong and the first dash is just a marker in the sequence. So I will just call this Beacon L

Signal strength is still high here at home. Battery voltage is unchanged at this posting at 12.9 and temp is at 33.

Had a thought that maybe the recent "L" beacon on 4096.12 was rebuilt?

Am wondering if in this new beacon's sequence if the "L" is a placeholder for digits that might be sent when daylight hits a solar panel?
It could be that no digits are sent when things are dark. Will check in the morning.

I was checking on DW and Windy and saw a big CW signal nearby on the KX3's panadaptor.
So I tuned in to check out the Morse.

8 dits
TMP  35
BAT 129
8 dits

Repeats about 45 seconds. Assume temp is in Celsius.

For the heck of it I tuned in to Gendarme and lo and behold....

6627.2 KHz  Gendarme. Weak but easily recognizable on my KX3 here at home

Summer in MN is glorious but brief.  Nights are short and the sun never gets all that far below the horizon.  Compared to long winter nights, this isn't favorable for receiving 4MHz beacons like Windy and DW.   Propagation predictions show this and my own experience is consistent with them.   The last two nights have had very quiet conditions in terms of geomagnetic conditions, lightning, and local noise.  But the beacons are weak here in the 0900-1100Z predawn hours, rising above the low noise floor only briefly.    I get clear IDs from Windy, but not full frames of telemetry.  DW is mostly just a ghost of an image on the waterfall.   Oh well, it is a great time of year to enjoy the outdoors instead!

DW and Windy seem to have fairly "big" signals 24/7 but there is no way I will ever hear CryBaby in the eastern Rockies since it only runs 10mW and only during daylight hours.  This is where SDRs are so useful whether I live in California or Minnesota.   ;)

I temp of 114.....that's a lot !

Nothing electronic likes that kind of heat....especially things like electrolytic caps .  It must see direct sun at times.

Based on DW's telemetry data and assuming the temps are Outside and Inside, the data shows a delta of 5-8 degrees typical. Therefore I don't think there is much in the way of direct sunlight impinging on DW's box. I believe the delta to be the product of internal heating due to power consumption. Conventional electronic components are designed to operate with upper limits generally set at 158 F for commercial applications. Good electrolytic caps are typically rated at 25,000 hours service life at 70C/158F. Chinese quality can be a crapshoot but I have to say I have had some Baofeng UV5R's in 24/7 use for three years without failure.
