Radio, railways, stuff...

Well, sort of. On FT8 I mean. I just received a couple of transverters from the transverters store in the Ukraine. These are not the newer model with the TCXO but are cheap and cheerful. Yes, they do drift a little but it's a toe in the water for me pending something else later on. I already have the Spectrum Communications 70MHz transverter and that works nicely but these are small units when compared, so I got a 70MHz and a 144MHz one. I connected the 144MHz one up today and set the FT450D to 28.174 and immediately heard FT8 tones. I'd not even fired up WSJT-X but sorted that quickly and made my first 144MHz FT8 contact within 2 minutes of turning the transverter on - followed by one further QSO and an indication via pskreporter that I had been heard all the way in NI. Yes, I know this is a minor achievement compared to those of other radio amateurs but it's still a new one to me... I now plan to sell off some kit including the Trio TR-9130 which has worked well. The one thing I don't like about that set is the notchy and fairly slow tuning when in sideband which makes it hard to scroll across the band looking for signals - having the transverter means I can use the FT450D's tuning which I am far more used to.

I've been fiddling recently with trying to receive satellites but without all the going outside and waving yagi antennas around... I've heard a few QSOs on DIWATA 2 and there is a very good pass in a day or so where I may be able to get a call in. This is using the Trio TR-9130 as receiver as it has a horizontal dipole connected, and the FTM100DE as transmitter, though so far without success on transmit. Anyway, I remembered the FTM100 has APRS built in and the ISS often sends and receives this in 145.825 and so I've been leaving the radio switched on. Today I noticed it did indeed receive packets from the ISS. I also downloaded UISS by ON6MU which seems to 'just work' - nice that, I downloaded it and ran it and it found the sound card and returned an APRS message on a later ISS pass. Oddly, the FTM100D did not decode that message (the squelch is set to 0). It comes with a module called SoundModem by UZ7HO which seems pretty comprehensive. Another package to play with...

A minor project requires a metal enclosure so I got one off eBay. I have a 5V PSU and three Pi's to install to keep these all nice and tidy. The enclosure is sized to take the PSU and has ample room for the Pi's and a fan. The enclosure arrived and is surprisingly well made for the price. It has plastic surrounds front and back. The front and rear panels are held with screws and the top comes off. There are two metal runners inside to maintain the structure with the top removed. Not a bad little case. The only odd thing is the description. Apparently the features of the case are 'surface mounted', ok I expect this means 'sat on a desk', and 'underground electrical enclosure switch junction box'. Not so sure on that one!
