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 😊

VHF/UHF?

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

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 ….

Me too. What’s the app running on your Mac?

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
