I finally fixed some issues with the BITX40 and had my first QSO with it today (YU1XA, report 55) - two years after I purchased the kit. There are still some issues but I am on the right track.

On a sunny day this week, we gathered and constructed a bench for our #OpenSource #Garden in #Berlin so we and others can sit together and grow our passion. Thanks to everyone involved and our decent neighbours ^^

got any favourite zines?
I'm looking for some zines to put in the little free store.
bonus points if:
- Black and white
- Nothing too radical (aka, accessible to the general public not something that needs you to know a bunch of anti-capitalist/leftist terms and concepts)
- Has a format online that I can print
- diy/how to stuff (i just like it)

I got a digirig after seeing someone here post about them. It arrived earlier this week and I just made some cabled to connect it to the FT818.

So far I am super impressed! Also, I learned the 818 can do CAT controlled PTT.

Details at: and I'll write up my experiences shortly.

The final result is:

* R = 25%
* G = 40%
* B = 36%

As expected (and described in the thread), the gamut is pretty low (ie. not an immense possibility of colours, due to fact that masto polls options sum is 100)

0..100 to 0..255 (in gimp) give:

* R = 63.8 (64)
* G = 102
* B = 91.8 (92)

HTML: #40665C

It's a soft, dark, bluish green!

It's complimentary color is #66404A (102,64,74)

Its triadic scheme:
#5C4066 (92,64,102) and #665C40 (102,92,64)

We could call it "Fédi-vert"?

Started another #homebrewcomputing build of an #ibmcompatible : again a Micro-8088 board, an RTC8088 board and an #XTIDE . The #CGA card is a real old one, which will eventually get replaced once (if) I complete my IBM CGA clone. My plan is to fit my EMS expansion card, my quad serial, and a Gameblaster/CMS clone in here. #retrocomputing

Short intro!

I'm trying to get back into ham radio. I've had license since 1999, but just now building my first HF setup. I have a lot to learn.

I'm currently interested about learning HF and digimodes (FT-8, JS8Call, VARA). Just a bit over 10 QSOs on logbook now. I also hope going outdoors portable to do WWFF activations when it's not freezing cold in northern Finland.

Currently I have second hand FT-891 and temporary random wire antenna to get on air. 73

Today in the exiting episode of HUB does ham I built a 49:1 transformer (some call it unun) to be used with end-fed half wave antenna ().

Box was too small, my fingers too big and result is not beauty. But if this one performs at all then I'm going to build a new and better one!

There's two FT240-43 toroids stacked, windings done with 1mm magnet wire and one 100pF 20kV capacitor. Hardware is M6 because that's what I had.

It's illegal to enter buildings in the zone as most of them are completely unstable, and due to a new zone administration there's typically no bribing your way out of a situation. Sometimes in the most unsuspecting places you may find street art left behind by a Stalker who risked arrest for something many will never see. Somewhat of a real life Easter egg, or a subtle nod to defiance: "You're not suppose to be here."

- Hey everyone.

My interests are still TBD. I decided to get my license on a whim. I knew nothing about it. In the process of studying / reading about this, my mind has been completely blown. How did I never hear of this whole network of repeaters before?! Or APRS and this radio based messaging thing?! So many cool things out here to learn!

I'm mostly in VHF/UHF space for now. I can see my future interests branching into and HF.

Day job is tech/software devel.

Did another batch of online ham exams today and took some time after to improve the google sheet where I keep my records.

Delightfully, noticed that 100% of people who've taken the Tech exam during sessions I've been part of have passed. That makes me super happy.

General: 91% pass rate
Extra: 68% pass rate

That actually tracks pretty well with expectations that higher license should be harder.
