Hello Hartmut and Group, Even with only 65 watts from the TX, strong QRSS100 signals were seen on Hartmut's grabber at 137.777 so the power was cut to <10 watts by reducing the drain voltage of the c

I was about to announce that I would be transmitting in the odd hour slots-start 15 minutes after till 30 mins after and agn 45 minutes after till top of the hour. Will that mess things up? Bob WE2XE

Hello Joe, thank you for your kind words! Still struggling here with my local Pest DCF39. Between 03:15 and 04:40 UTC DCF39 was sending a higher pulse frequence. That is the reason of the higher nois

Hi Markus, That is most interesting. I remember that occasion when TX was on later than usual. It will take a bit of tinkering to get the phase coherent exciter to the class E TX, but this is long ov

Congrats on your grabber, Markus. The output was less than 5 watts, 0.4 amps RF so this is a true QRP TA reception. It almost appears as if the QRP path is a bit to the south by the greenish colour.

Joe, when you were sending CW a couple of days ago, the coherent carrier was detectable in my 438 uHz spectrogram in broad daylight, until 12 UT! So I'm wondering how a low power straight carrier wou

Hi Hartmut, Yes, DCF39 must be a real pest as it is so close geographically and in frequency. You seem to be dealing with it very effectively. Thank-you for running the grabber. It's a pest over here

Yes Joe, 100% duty cycle would be ideal. But occasional CW or QRSS id's won't hurt either, as long as phase is being preserved. 73, Markus From: Sent: Friday, January 10,

Hi Markus, Carrier on since 1920 UTC. 5 watts. While looking at the messy breadboard and trying to draw the schematic, I decided that it would be quicker to just run the Decca using the power supply

Hi Hartmut, Thanks for running your grabber. If one squints at the spectrum around 0600, a callsign can be seen. Amazing reception for <5 watts! 73 Joe Am 2014-01-10 19:44, schrieb : The

Joe, can't really say I'm seeing much here so far. Not even in 438 µHz, except for a couple of dim pixels in a row around 21 UT. Hartmut's grabber is doing much better at 11 mHz! Best 73, Markus (DF6
