My camera’s groundglass (Canon EE-s) got dirty and I had to replace it.

I ‘ve just finished the fliphack on my HV30, now I don’t need mirrors to flip the viewfinder’s image. It was not very difficult to do, but took a lot of time. I followed this guide.

Single-sideband is one of the most popular modulation modes in analog voice radio communication today. SSB avoids the bandwidth doubling and unnecessary carrier emitting of amplitude modulation, thus concentrating radiated power only on the signal that carries the important information (for ex. voice).
If we take a 2KHz sine wave (modulator wave, this is the information [...]

At last! My greatest work completed! :)

Finally I was able to talk with HA1TN Noybi, he’s in Budapest in a building estate with a 4 meter fishing rod antenna on the balcony. We could talk using only 5 watts. Great!

We put up the 12m steel pole today. Here are some photos:

The next thing to do is to rent a mobile crane and put up the antenna. I haven’t decided yet which coax feedline I’ll use, RG58 or RG6 (we have lots of RG6 in our shop).

We put up 2 new antennas to the roof in the last few weeks. Thanks for my father for helping me out, I’m pretty agoraphobic on this steep roof. :)

The first one (it’s on the left on the pictures) is a brand new Diamond X200, the second one is a homebrew j-pole. I’m using the [...]

You can find the plans and specs for this antenna here. No balun needed, 50 ohms at once, works perfectly fine. I’m using it on a 4m long (telescopic) landing net pole.

I still don’t have my HF antenna up… :( Spring is here, and my dad had some free time on the weekend, so we started to prepare the place where the steel pole will be standing in the corner of the croft.

More pics are here.
After breaking up the concrete we put down a grounding pole [...]

I want to use my radio on HF bands, so I had to look for a reasonably sized multi-band antenna. I found that the 2 most popular antennas in this area are G5RV and W3DZZ.
The former is fed using a ladder-line cable and I didn’t want to mess with it for my first HF base [...]

I’m planning to buy an amateur desktop/mobile HF transceiver, so I made a little desk for it from some chipboard I found in the storage.
