Preparing the FT817

Getting closer to being portable - not that I go anywhere! I now have an LDG Z817 automatic tuner. It seems to be working fine although it arrived with dead batteries, one of which had leaked a bit. That cleaned up ok and it now sports a set of Energizer Max batteries (ok, I had a box...) Having run up FT8 on the Mac 40m was packed but I did manage a contact with an EA station on 80m with 2.5W via the random bit of wire in the loft. Note to self: remember there are batteries in it!

I did a bit of experimenting today with WSJT-X on the Mac and using the FT817. So far, so good. Ok, no surprises there, lots of people are doing the same thing! This is part of my master plan (I'm up to Plan G so far I think) which involves using the FT817 for VHF / UHF instead of the FT450D and transverters and switches, and being able to take the kit elsewhere, either in the UK or abroad. The only laptop I have is the rather old now 2013 MacBook Pro. Still my workhorse for just about everything, I tend to run it plugged into power and with an external monitor. But the battery still holds up for a good while. I wanted to get a Mac Mini because I always use the laptop with the screen closed, using a wireless keyboard, trackpad and mouse, and wired Ethernet. Mostly it works fine, just sometimes it manages to jumble the size and position of all the windows when logging into the thing. No biggie. But used 2018 Mac Minis cost a bunch, so I'll stick with this for now. WSJT-X went on just fine - again, no surprise there. On…

I plan to use the FT817 portable but also for VHF and UHF FT8 and other digimodes, so I wanted to upgrade the standard oscillator to the TCXO version (Yaesu's TCXO-9). But these are scarce, at least in the UK. I've searched for a while and got nowhere so I ended up buying one from Wimo in Germany as they had them in stock. The original TC1 unit (left) and the TCXO-9 (right) are, of course identical in size and sit on 7 pins. There are at least two variants of the TCXO-9 and I guess this one is the newer of the two. The unit is easy to install. Obviously - or it should be! - disconnect the battery, wear an anti-static bracelet or take appropriate measures, then the old unit simply pulls off of the 7 pin connections and the new unit presses in to replaced it. With the set back together and given a little time to warm up, and set up for CW it holds steady just 2 hertz high. That should be good enough for data modes!
