I was using Enigmail with Thunderbird <78. When Debian Bullseye got the Thunderbird upgrade, I followed the wizard to import my Enigmail settings into the built-in PGP. It said it needed my passphrase to do this. Seemed reasonable at the time.

Now it gleefully decrypts everything without any prompting. This is unacceptable as it means it has either my key passphrase or the decrypted key matter cached somewhere.

How do I rip this out and start over without killing my entire T-bird profile?

Actually, HF propagation is not very good at night, and night comes early these months ๐Ÿ™
My setup permits only 30m, 20m, 12m and 10m. Maybe I should build a 40m antenna for night QSO? Is there a good propagation on this band right now?

2020 was not a very good year for many people. However, it permitted to have an intense radio activity (in two words, of course, a nuclear disaster would be the icing on the cake ๐Ÿ˜ฑ).
Here is a map of my first year of QSO. Certainly very light compared to usual operator, but I'm nevertheless proud, even if majority are FT8 contacts ๐Ÿ˜Š

(map built with if you want to share too !)

Watch me present a live talk โ€œTowards a Small Webโ€ to students at the Howest design/development programme in Kortrijk tomorrow (Friday, Dec 4) at 2PM Irish time/3PM Belgian time.

I will be demonstrating a very early proof-of-concept on for the first time (setting up your own small web server in ~30 seconds).

Watch live at:


Soon first year of my PMR446 contest will be concluded. The November round showed that it's indeed possible to do QSO from the Czech republic abroad, even though the specs of PMR446 devices would at first sight seem to be unable to do so.

So HAMs from neighbouring countries - I invite you to listen on PMR446 every 4th Wednesday between 19:00 and 22:00 CET/CEST and if you hear some unusual activity, don't hesitate to break! People here know English, even though we do most QSOs in Czech. Last round the 520 km distance was reached, maybe it can be even improved (this is probably continental european record on the band as the 536 km from Britain to Netherlands from 2003 was over the channel, which is easier). Even the main czech CB+PMR portal map was not able to picture the QSO as 20 years ago nobody expected such distances :-)

I need some help with setup on AT-D578UV. I do not manage to send my GPS location on
I don't know which setting I miss.
When I press PTT on Channel "APRS A" (see sccreenshot), it transmits APRS data at end of transmission.
But nothing appears on

Any idea ?

And you have to get it from a website or another user or you can build it with the channel/config editor provided by the manufacturer?

With DMR, I don't really understand the notion of 'codeplug'. Is it only channels and setup of talk groups and relays, or is it an additionnal software used by the transceiver?

Finally, Anytone AT-D578UV DMR rig ordered !

2 Timeslot, TDMA, MOTOTRBO Tier I & II

50W VHF and 45W UHF
RX and TX on 136-174 MHz / 400-480 MHz

GPS and APRS function in FM or DMR
dual display, dual standby
Bluetooth with PTT button
SMS function via the keyboard
Registration function
GPS function

Delivery on next week ๐Ÿ˜‹

Anybody has tried the Anytone AT D578-UV PRO

I was not looking for a digital radio, but finally, if I buy something new, it's a better idea to buy a TX with all features I might regret in few months.

Is this model compatible with digital channels you use (if you do) ? I would be happy to contact some of Fediverse friends ๐Ÿ˜Š

Yesterday there were special conditions on UHF bands affecting the free PMR446 band. Many 300+ km QSOs were made, several over 400 km and there was one from Czech republic to Hungary which was first ever and it will attack the world record for PMR446, which is limited to integrated antenna, 0.5W and FM modulation. I'm glad I organized the event and made people go to hills in the middle of the week!

Well I'm a tech nerd with special interest in all things radio and old Z80 computers.

Hamwise I'm mainly do digital modes, both HF and V/UHF. Also some non ham LoRa.

Besides tech I'm interested in all things science, specially astronomy.

I was really thrilled to find a ham focused mastodon instance.

Which chat service/protocol do you prefer? #matrix or #xmpp
Boosts appreciated

I'm looking for a VHF/UHF tx supporting FM (no C4FM or DMR needs) with at least 50 watts on 144-146 and 430-440 MHz bands with CTCSS, 1750Hz tone, repeater shift. PMR 446MHz band would be fine.
Yaesu, I-com, Anytone, TYT, CRT... propose many models and I'm lost. Which model would have all these features, good feedbacks and not too expensive?
Thanks for your help
