My 630m WSPR New One: OY6FRA

Last night I’ve had a session of WSPR and Opera on 630m, added a new one for me in WSPR: Faroe island with OY6FRA, 2627 Km.

Despite map’s appearances the best DX was with EB8ARZ with 3008Km.

A total of 83 stations copied my signals.

U3S stuck :(

Just now my U3S transmitter is blocked in TX condition as is possible to see in the next picture:

DK7FC grabber

The continuous line over 475.740 is my signal more than one hour long. The problem is that it was an unmanned operation and I’m not at home now. Strange […]

A small summary of the last months

Here follows a PDF doc where is possible to see all my unique stations transmission report on WSPR MF band, they are in descending order of distance. I still didn’t compiled a ranking by country but it’s easy to see how many DL and G are in the log.

Grabbed Iceland on 630m

Finally my signal came out from continental Europe reaching Iceland.

44 stations copied my signal and 3 times TF3HZ received my weak signal:

136 kHz… finally!

Last night was my second “serious” TX test on 136 kHz, transmitted Opera32 mode after an upgrade to the matcher.

To tune the antenna on 136 kHz I’ve build a couple of inductors over two hand cleaner soap bins. The first one was wound with enameled copper wire of about 1 […]

QRSS10 & WSPR dual transmission last night.

Due the lack of public MF grabbers on the net, last night I’ve tried to receive my signal in qrss10 with remote WebSDR system. I alternated the two transmission mode so to have an idea about where my signals were received.

With great surprise receiving myself on Twente WebSDR my signal was audible and even […]

3rd August solar storm MF observation

For the expected solar storm of last 3rd August, I’ve planned a continuous 72 hours transmission of my MF station as QRSS10 beacon since 1st of August afternoon. I’ve monitored my signal on the MF grabber of Stefan DL7FC, comparing it with IQ2MI signal, downloading for the 72 hours a picture any 10 […]

Increasing TX antenna capacitance

This is my umpteenth upgrade to the TX antenna to try to get better general performance and get the possibility to work on 136 kHz without tons of electrical wires outside the terrace. The new layout is drawn in the next basic picture: I’ve passed from 4 top wire and a single vertical […]

Toroid matching for LF/MF

Since my antenna was born as monoband for 630 meters, until today I’ve used an autotransformer built around the variometer. In these days I’ve tried to tune the antenna on 136 kHz, beginning to put some mH over mH to reach my goal. Arrived to 136 kHz I’ve sadly found that the autotrafo […]
