22 Meter Band HiFER Beacons / Re: YCPA 13567
« on: February 15, 2020, 2320 UTC »
Hello there,

Nice to see another beacon in Pennsylvania. Grid FN00 Allegheny County. My beacon Abby is running around 135564.9 frequency change from 13566.9 due to changes in components. Today try to run 100% solar.

Have fun.

Awesome! I saw your posting for Abby and have been tuning in hope to catch it. I am also quite curious of your solar experiment. I have plans drawn to feed mine with solar as well, using series 18650 batteries to keep it operational at night with hopeful charging from the solar cells as well.

Eventually I may expand to a more robust system, multiple beacon boards, different bands, controlled based on time and via an arduino. Almost like NCDXF, but single location. This is definitely a few months out yet. I am still learning this building stuff, tried to build my own, failed but learned where I failed based off the 22m kit, so it's back to more experimentation :D.

I hope to catch Abby when everything aligns perfectly for me to do so :)

22 Meter Band HiFER Beacons / YCPA 13567
« on: February 15, 2020, 0356 UTC »
Greetings all,

Just finished putting together a Black Cat Systems 22m beacon.

It is currently turned pretty low on the output power until I can get it on a scope, and grab a field strength meter from the club.

The beacon is currently tuned to 13567 but may fluctuate with temperature, etc, standard crystal stuff.

It is fed into a 1/2 wave dipole roughly 10' up for now, broadsides facing NE-SW. Beacon location is York County, Pennsylvania (hence the call) FM19rx grid ~400' asl)

Happy hunting!

Morning all,

Over on YouTube channel Clemens, there's been a LOT of (since my listening hobby) voice activity on the UVB76 transmitter.

The most recent being "failure" over and over, the letter H in succession and multiple times then 3 sets of 2 digit numbers to finally end with H's in cw and back to buzzing *head scratch*

Has anyone else been watching this? If so, have you noticed any correlation between The Pip and the Squeaky Wheel?

I am currently listening to and recording Squeaky Wheel via UTwente's web-sdr to see if the same transmission (or completely different ones) appear on this Russian station at the same time, different time, same message, all that stuff. Since Clemens focuses on The Buzzer, worth a focus on another, sadly I don't have followers nor a channel like he does to perma-livestream.

If I notice anything I'll be sure to post, just started tonight. Dumping the browser recording to the NAS along with Audacity recording just in case. Plenty of storage for daily review.

73,

K3ZRT, Jeremy

22 Meter Band HiFER Beacons / Re: Using a 20m Yagi for reception
« on: February 12, 2020, 0309 UTC »
I don't know that many do, but I don't see why it wouldn't suffice. A tuner would help a bit but it's close enough to work.

The great thing about reception is you don't risk blowing anything up, experiment! Try it out, if it works than yay, if not then back to the drawing board.

Hearing EMPHASIS(?) right now.

Heard from my location too earlier.

"EQPLLHIFISLOL7RTSR46JJ6FDE3XWQ This is Emphasis out."

Was all I caught by the time I thought "Hey, I should write this down".

I can't help but sense the irony lol tho it is pretty common, at least in the North East on my end. I get a lot of whistles, chatter, or annoyance trying to hear what's going down on 6925. Nature of the beast sadly, filters may help tho unlikely due to proximity unless you made them super tight, tuning different modes may help (am station, tune the sidebands, etc), change antenna location sometimes helps (my base receive vs my car about 30 feet away and 10 feet lower, antenna to antenna, does have different reception esp at 7mhz area). However, it's an open market of interesting eavesdropping 6.9-7mhz to be sure.

As I make a new account, check new unread messages, and work on interfacing my board to my yeasu 857d...

I just received my Behringer interface from "the big A" and couldn't be happier. It's exactly what I needed to get my board, mic and transceiver piped to the laptop with ease and better quality than straight in to the laptop (line levels and such).

I'm currently sitting here playing with cables working out output from laptop to board to radio, while retaining the current "recording mode" setup.

Dunno if it'll help sway your decision but for <100 bucks you can't go wrong with an audio interface if you're doing line level work to your PC.
