I've now got a Heltec Wireless Tracker for 70cm LoRa APRS (439.9125 MHz). Using it inside the car but still pretty good range.
Find M1AVV-7 on APRS.FI
Along with a 868MHz LilyGo T-Beam running Helium Mappers.
Upgraded my laptop - HP Probook 640 G1, from 4 to 8GB RAM yesterday. Still running Windows 10 on it.
But I am running Windows 11 on my desktop (still got the AMD FX8350 from 2013 so it's not officially supported).

After 8 years without a HF SSB transceiver of my own, I finally got one at Xmas.
A uSDX which covers 3.5 to 30MHz at <5 watts. It draws 900mA max at 13.8v and 80mA on receive.
Set up a dipole in the loft which is resonant at around 7 and 21MHz, not by design, that's just the amount of wire I fitted in there.
Power output from the uSDX on a 13.8v PSU:
1.8MHz = 4.5w 0.74a
3.5MHz = 3.3w 0.51a
5.3MHz = 3.8w 0.65a
7MHz = 3.0w 0.85a
10MHz = 3.1w 0.52a
14MHz = 2.7w 0.53a
18MHz = 2.5w 0.4a
21MHz = 1.7w 0.37a
28MHz = 3.0w 0.66a
It's been a while since I posted anything here.
I've been playing with Meshtastic on my T-Beam, quite a few nodes locally.
Also, the usual FT-8 reception, WSPR using the SOTABeams WSPRLite from my car and a few 2-way contacts now and then (4 this year).
Using a Lilygo TTGO T-Beam to run Helium Mappers software. 100mW on the 868MHz band.
What is Helium ? Seen a load of small vertical antennas going up on nearby houses? Wondering why the price of good coax cable just rocketed? All the important things you need to know are:
OLED display comes with the unit but needs soldering on (4 pins)
A professional car installation, perfectly balanced on my phone holder
There's a holder for a 18650 cell but it runs on a USB power bank and no cell
Mapping the A590. This area was previously uncharted territory. Some transmissions are getting across Morecambe Bay from inside the car (see top right, receiving hotspot is at Heysham)
Some good locations in Barrow, getting across The Bay
