Radio and rails...

Certain websites are becoming terrible these days and for no reason other, I suspect than poor or non-existent testing. I am actually trying to buy a cooker hood. I made a shortlist of 4, one poor, three ok. I went with one from a company but when I got to the ordering screen it wanted to add nearly £15 for delivery. This had not been made clear before. So, the second choice was from Amazon, free delivery. I tried to order this in Safari on the Mac but, after logging in and adding the OTP code I got a blank screen. So I tried via the DuckDuckGo browser - same thing, a blank screen. Plenty of code, pages of scripts and obfuscated stuff, just nothing rendered. I resorted to the Amazon app and this time Amazon told me the product cannot be delivered to our address. No explanation. Anyway, goodbye Amazon. Again. I actually ditched Amazon when as a Prime user paying annually they decided they were going to inject adverts into films even though I was paying for Prime. I ended up paying the delivery charge with the other company. KLM is another infuriating site. I can do everything…

After our trip to Europe and Japan I really want to do FT8 or other digimodes - my preferred mode because of naff hearing etc - rather than just take handhelds. But the weight of the FT818 + tuner + PSU + a laptop is prohibitive. True, the PSU and tuner would go in the checked bag but I feel that the FT818 would really need to come as carry-on. And anyway I do not own a laptop, plus the fact that we tend to travel light so there is very little room for my stuff anyway. So it got me thinking. At home I use one PC for Linux, one for Windows 10, the Mac mini, and a Pi. Four systems, four screens, and great flexibility as all the audio is interconnected by a mixer. But the Windows PC is now playing up and is too old for Windows 11, not that I want that but I guess it is inevitable as running Windows without security patches is just about the worst thing I can imagine. Well, ok, my imagination runs a lot deeper than that, but you know what I mean. The QRP Labs QMX+ looks most interesting,…

We just had a short trip to Europe and then Japan and so I took a couple of handheld radios along. For Europe the CEPT licence was fine but for Japan I arranged a short term one via JARL who were very helpful. So, licences and HTs in hand, or, rather, in carry-on bag, off we went. I had broken the radios down into battery, radio and antenna and put each in a plastic bag to keep everything clean. Big mistake! My bag was searched at the UK airport and in Schiphol. The bags were causing confusion, especially as, at Schiphol they asked how the battery related to whatever the Mouser code was on the old plastic bag I had used. Very quick though, it only added a couple of minutes each time and they were happy. So I left the radios intact for the onward trip from Schiphol and into Japan. No issues at all at either end or on the return. So... note to self, leave the radios intact.

I wanted to get a programmer for the ID51. So, off to RT Systems as I have some of their programmers already. Got the Mac version of the package for the ID51 but it does not allow programming via SD card. That caught me out because their package for the FT2D does and I wrongly assumed this would too. Of course, it needs a cable! Off to eBay… an allegedly suitable cable arrived today but the RT Systems program will not find it. Typical, it needs one of their enfangled cables that are incompatible with the rest of the world. No way that will arrive in time for our trip. So… Chirp then. Downloaded the Mac version but it, too will not see the eBay cable. I know the Mac sees it so why won’t the software? RT Systems has no option to select a USB port, Chirp does but offers no help as to what it is. Try Linux? Hmmm… I’m really not into fiddling with flatpack or any other enfangled package managers - apt is enough, no apt, no use. Windows then! Got Chirp, and it can find the cable, and Chirp will see it and will download…

"Zilog has called time on the Z80 CPU." (https://www.theregister.com/2024/04/29/opinion_z80/) Wow. Actually I had no idea (through never having checked) that it was still being produced. And a fine chip it was too. I never built a system from wires up using the Z80 though. My first system, designed, built from chips and wire-wrap was an 8080 system, hand programmed to control al x-ray diffractometer. This was decades ago now but I still remember it, although I have no photos unfortunately. The system had a timer chip for a 1-second count and was interface to a Nuclear Engineering (I think it was!) counter that used nixies. But I did at least use Z80s, just they came as boards. The first was a Transom Triton computer and by then I was programming in Turbo pascal - back then this was really neat as one could have procedures full of assembler code which made interfacing easy. Later I used Gemini boards and that also gave the ability to have a graphics card. By then my interfacing to the diffractometer included a stepper motor and shaft encoder to control the arc motor. In the end there were two sets of Gemini Z80 boards, one…
