I was going to use a relay but then of course you’ve gotta have some digital output from your laptop to drive the relay which I haven’t figured out how I’m gonna do that yet. Probably some python script talking to little ESP 32.

I’ve been working writing a Gnuradio AM/SSB/FM transceiver for the Pluto that will work on any frequency but interested in what you’re doing with the antenna switching

Great. Anyhow I like your concept of an antenna that's not going to freak out the neighbours 😊

And we have Meshtastic - we are seeing up an internet resilience comms mesh across Melbourne for when they all go out!

Built a raspberry pi powered remote triple receiver for Lora Meshtastic, ADSB, and an Airspy mini for the roof. #sdr #hamradio #adsb #meshtastic

Quick home made random wire - printed the winder. Wound a 9:1 un-un and 41' and 17' wires to be used with a QRP ATU.
Now for some field tests 😊

Thanks, Chris. I’ll check it out. I realise that at the end of the day it’s really just practice practice practice 👍

Thanks Jim. I’m usually out swimming or bike riding around sunrise. I can’t bring myself to the sit inside and play on the radio unfortunately, but next time it’s raining ….

Thanks, Jim. I’m gonna practice a bit more than I might give it a try one day soon. I have never had a single CW contact in my life but I’m feeling a need to do it.

Do you ever get any VK3’s on the SST?

Which ferrite? I've only been getting around max -40dB for 43 material with a usable range of < -30dB for 3 MHz to 46 MHz

Had a lovely week up in the Victorian Alps alternating hiking and mountain bike. Took the IC-705 and had some good contacts on 40m and 20m QRP
