Yesterday the IceConeFeed v2 from Patric - DC8PAT - arrived well-packed and preassembled with the Golden Media 202 LNB.
I started my journey into QO-100 with a very simple setup. Details can be found here. The previous setup consists of the well known LimeSDR-mini, a pre-amp and a modified WiFi-amp. No I placed all the components into an old case - not so fancy but sturdy.
I started my journey into QO-100 with a very simple setup. Details can be found here. I used purely SDRConsole to receive & transmit audio via a simple USB headset. This was no real comfort and it was not capable transmitting CW ;-)
Fortunateley Andreas DL4JAL published 2021 in the German ham radio magazin FUNKAMATEUR an interesting hardware console. The basic idea behind this console is, that through the internal soundcard SSB-audio as well CW-audio can be transmitted. A hardware PTT key can used to switch SDRConsole into transmit mode. Furthermore it controls the timing for T/R-switching - SDRConsole has some delay between audio input and rf-output via the LimeSDR-mini - so no loss of last DIT or syllable.
Inspired by the webpage of SARCNet, I decided to build the SARCNet MK1 rotator.
Here the first impression of the unit I've build:
Based on the publication of Matthias, DD1US, I bought from him one of these TMT H3930 isolators - Thanks Matthias for supporting the community!!!
In search for a suitable pre-amplifier for the SG-Labs PA V3 I was pointed by a fellow ham to this amplifier on Amazon for abt.€17,-
My previously used pre-amplifier (the one in front of the final PA) only delivers a gain of abt. 9dB @2.4GHz. This was far too less for my final PA used.
To protect the fragile LimeSDR mini PCB I placed the SDR inside an aluminium case.
I received a new WLAN grid antenna from a fellow Ham - thanks for this!
Here some pictures of the recent SSTV transmission from ISS. They are received using a cheap SDR stick and the NOAA antenna from WIMO under the roof abt. 7m above ground. Decoding is done using MMSSTV.
First of all - a lot of money :-/
