Its time for leila to start working.
Many stations with far to much pwr on the uplink
73s DB8TF
i am surprised how ignorant the HAM's are who working with faulty parameters

Maybe someone can become policeman and simulate leila from his ground station? I mean, TX on aligator channel siren manually.
... if I switch to horizontal I can see some stations 15 dB over the noise floor ... ?!?
I think a good indicator to see if the signal is to strong ...
Heard someone say they thought the recommended max level was 10dB above the beacons yesterday, rather than same level as the beacons.
From what I 'roughly' read is that the people sreaming for a jammer are not active themselves.
So, first become a 'user' (i.e. transmit yourself') then complain.
If you're not able to transmit, refrain from comments . <- period

even if someone receives this is a form of acitivity.
What´s your comment?
My comment? "Build a transmitter for 2400 MHz" (and join the party)
After all .. the rationale of the legal radio amateur service is that one is allowed to transmit (inside the HAM bands of course)
Free translation from a Dutch saying: "Don't whistle with bisquit in your mouth to the football referee in the field, while you are outside the playing field"
QRP OR QRO???
Saturday Fe. 16th 17:08
just returned from GHz- Tagung Dorsten and found a real QRP signal: 549 on .571
QRP test 75mw into 95cm dish de PA1SDB Winschoten
well done!

wow
He actually is 10dB above the noise here so it could be a lot lower...
Hello Heiner, I have also a board with the PE4312. Where can I get the Arduino LCD Display and the software code for adjustment?
My Transverter and PA is 50m away from my Shack. Is it possible to adjust the PE4312 remotely?
It would be nice to have the attenuation value visable in the Shack. So I could also adjust the power by remote.
surfing the web I found these two:

which look quite interesting as well.

DL2NED So back from work..here my answers for you.
1. Arduino Uno plus LCD Keypad Shield together around 12Euro look for good prices on Ebay.
2. The program I can share with you by email just drop me a mail dd0kp@darc.de
3. I did a small interface to I2C with a PCF8574
4. You need in addition I2C extenders for your cable length look this link:
https://www.hackster.io/chipmc…-and-inexpensively-ea6b53
5. Best you use a simple Ethernet cable for Vdd, GND, Clock and Data lines.
then it should work remote from your shack.. regards Heiner..
I ordered this one, expected it to receive tomorrow https://nl.aliexpress.com/item…042311.0.0.666d4c4dc2ZRQI
PH2M also looks nice...
Yes and external control later is always possible !
Thank you for so many information. This device can also be used for longer I2c distance:
