Radio, railways, stuff...

I finally got some wire in the air. Well, not very much and not very high, but at least it is outside. One end is attached to an eye bolt outside the shack window positioned so I can reach it with the window open wide. From there the wire runs down to the workshop. I am not exactly sure of the length, Google Maps suggests just short of 30 feet. So pretty short! But it works, and the FT450D internal tuner can cope with it from 30m to 6m, except for 12m. Anything lower than 30m has SWR approaching 3 but otherwise it seems to be ok. Pity the sun is being naughty right now but it gets a good spread across much of Europe on 20m. The wire feeds a 9:1 (I think!) unun and a 1:1 choke, then RG58 (*) to the patch panel. The cable needs to be routed yet as it is currently just running through the open window. Signals received are definitely stronger than with the loft wire and Z11 tuner but it is hard to say exactly how much because of the time taken to swap leads, disable or enable the internal tuner, and tune the wire during which time the watched FT8 QSOs have ended and moved etc. However, with the TS2000X on and connected to the loft wire a random Italian FT8 signal was -17 on the TS2000X + loft wire and -9 on the FT450D + new external wire. Plus the waterfall on the two rigs definitely shows the advantage of the external wire. In fact, the wire length is probably similar to the existing loft wire. So now I really must get round to running a wire up the garden which will be a lot longer. (* Typical. I put RB58 instead of RG58, didn't proof read, turned everything off for work and just got back to edit it now!)

New (to me) arrival in the shack... something I've been toying with getting for some time now. This is a TS2000X and has the 1296MHz option installed. It will take me a little while to get acquainted with it but it brings more capability on 2m and 70cm and adds 1296. I've been using an FT817 on VHF for FT8 etc. up until now and generally running it at 2.5W - fun, but I wanted a bit more juice up there. The Signalink from the '817 is ready to go, just waiting for a CAT cable and some coax plugs as I've used all the ones I need. That will at least give me time to read about the rig before playing...

I dug my poor dusty MD380 out yesterday and charged it up. For a while now I have had Fusion and POCSAG on the pi-star but I rarely use the FT2D and when I do it's only for APRS. So I thought why not get DMR back into the pi-star. I have a dual DVMEGA HAT with pi-star set to duplex from when I was fiddling with the new HAT. Anyway, since I last used the MD380 I changed the rx and tx frequencies in pi-star to the 'designated' hotspot frequencies so the MD380 needed reprogramming. That's where it all started to go south... First off, since I rebuilt the Windows PC I did not, for some reason copy across the MD380 programming software. Ok, found it on the web and installed it. Can it see the TYT programming lead? Nah. This particular lead is basically a wire, it does not have a chip built in apparently and so needs a specific driver. Oh yes, Windows will see the lead and knows what the device is but has no clue about the driver. Ok. Found a driver. Installed it - apparently - it does not give an error but the rapidly disappearing screen on installation did not fill me with confidence. And no, it doesn't work. Tried another programming software suite called editcp (https://www.farnsworth.org/dale/codeplug/editcp/) in case that included the driver. Nope. The disk that came with the MD380, which took some searching as it is one of those small CDs and has nothing at all written on to indicate it is from TYT, also has the driver but it would not install either. Right. Over to Linux. It saw the device and lsusb shows a reasonable text string. The same editcp software has a Linux version. And, typical of Linux it just works. It read the radio, allowed me change the frequencies and programmed the radio again, no issues (*). I did have to remember just how to set up the codeplug as I wanted to use both TS1 and TS2... that took a bit of head scratching as it's been years since I fiddled with this. But a couple of useful websites (there are many others) helped sort my brain out and I now have pi-star and the MD380 set up for TS1 and TS2 with different talkgroups on each via the Brandmeister self service. (* OK I'll admit it took me five attempts to program the frequencies as I kept reading it wrong! FOUR times entered wrong before I got it typed in correctly)
