M0RVB ⁽³²¹⁾

Now the competition is over here is the best image I received during the Fram2 mission: I received several images in total including slides 1 through to 8, of which about half were full or nearly full images. The setup here was SatPC32 driving the TS2000X connected to a 70cm QFH antenna in the loft. This really needs to be outside but that will have to wait.

I grabbed one of these little guys off Amazon after spottong a review on Youtube. The SW28HF covers 1.8 to 50MHz at up to 120W. It is a tiny little thing wth an internal battery that would lend itself to portable operations, but mine sits atop the tuner. My only niggle is the charging port is on the front - personally I'd rather it was hidden at the rear but that's just me. It appears to work nicely, giving a readout which looks to agree with the bars on the FT450D and broadly with the LEDs on the tuner. It has a high SWR alarm that I have not fiddled with yet, and the single sheet instructions are clear and go into some detail of what SWR is and how high SWR can damage a transmitter which is a nice touch.

I made my first QSO on the QMX+ on 30m today. It is a nice little QRP radio, the one I have has all bands from 160m to 6m. Getting it on the air is a bit of a fiddle, not caused by the radio itself. I have a very shorrt random wire antenna tuned by a Z-11Pro II tuner that works very well with the big radios but the QMX+ needs to be treated carefully. Tuning at full power is a bad idea because the tuner is going to hit some very high SWR figures and damage to the finals is a real risk. But there is more to this tale... First off, I wanted to run it from my old MacBook but no matter what I did it would never see any data from the radio - the QMX+ has CAT and audio along a single USB. CAT was working fine in wsjt-x but no audio of any description. So I loaded wsjt-x on the Mac Mini but it crashed every time I tried to set the radio up. Anyway, I wanted to use the rather neat iFTx app on the phone which does FT8 and FT4 and…

One of my Pi 4B systems runs an ADSB grabber for Flightradar24 *. A few weeks ago it lots the SD Card so I rebuilt it. That card had been in for some time but I didn't record when. Silly. Anyway, a few weeks went by and it lost the new one. Now, rebuilding is not a huge issue as I record every step in a file, so rebuilding takes maybe 30 minutes and I never bother to image the SD card because if I add a step then I would need to make a new image etc. So I rebuilt it again but this time I added the SDD which was originally the server Pi disk (thay was replace dby an actual mini PC with a spinning disk). The Pi was in a 3D printed case but the SDD was just resting behind it on top of one of the radios. Off to printables.com - there were a few models for Pi systems with SDDs but none of the vertical stack types would fit. Then I found one which has the Pi and SDD side by side and it works really well. The Pi has a PoE HAT and…

A new toy arrived today, a Lilygo T-Deck Plus - basically a T-Deck with GPS and a case. I flashed this with the latest relevant verison of MeshCom and configured it, and it all works nicely. Not sure yet how long the battery will last but having it all integrated like this means I can wander round the local area and gauge how far it can be received by my hub in the loft. This is all on 70cm, specifically 439.9125MHz. And here it is:
