#hamchallenge week 14 - Make 10 contacts on a UHF/VHF calling frequency!

Time to call your local hams. Who did you reach? How long did you have to call CQ for? Which mode and frequency and which rig did you use? https://www.hamchallenge.org/challenges/15/toots #hamradio

#hamchallenge week 13 - Do something to get new people into the hobby!

Offer a course, convince someone to take the exam, donate money to people or projects who support newbies – be creative! https://www.hamchallenge.org/challenges/14/toots #hamradio

#hamchallenge week 12 - Sign up for an outdoor radio activity program and make a successful activation or hunt at least 10 stations!

There is a plethora of outdoor activity programs these days: SOTA, POTA, COTA, IOTA and even Toilets On The Air (though this mostly happens indoors HI). Chose one that you didn't yet sign up for and complete the challenge. How does it work? Was it easy to make contacts? Which references did you activate or hunt?https://www.hamchallenge.org/challenges/13/toots #hamradio

I managed to spend most of the weekend tidying up the shack. I now have the HF cables for my FT-710 and TS-2000 separately labeled, so that I can plug either into my window passthrough.

I also managed to wrap up all of my spare USB cords, which I have now placed into an old popcorn tin. I will likely regret this decision later.

🔎 Found a QRM source: an HDMI cable! Solution: It may not count as full success but turning monitor off when unused still satisfy me for IQ recording. 😇

I accidentally found a source of interference. I was scrolling over the bands when I noticed that that 80m was full of QRM that wasn't there a gew days ago. I was looking up 80m foxhunt equipment when I heard the tv turning of and suddenly the QRM was gone.
So I grabbed an AC filter and plugged the TV into it. It seems to help a bit (but not much). Still I count that as a success. HC10S

#hamchallenge week 11 - Großreinemachen: Clean up and label all cables in your shack!

How did you tackle cable management in a shack full of cables? What about the cables that run to your antennas? Tell us about your power cables, feed lines and computer cables. Do you use special cables to mitigate interference? Clip-on ferrites?https://www.hamchallenge.org/challenges/12/toots #hamradio

Mine wasn't strictly ham bands, but I installed new led lights and I noticed I got worse tv reception when I turned on a specific set of lights. Next was figuring out which fixture was noisy. I used an rtl-sdr dongle with my phone to figure out which light was causing the issue. Then I put a ferrite core on the power cable to attenuate the noise.

#hamchallenge week 10 - Find a source of interference in your home and eliminate it

How did you localise the QRM source? What was it and how did you mitigate the interference? How long have you been dealing with it?https://www.hamchallenge.org/challenges/11/toots #hamradio
