Amateur radio, QRP and stuff. 20W HF Amplifier with RD16HHF1 (K5BCQ’s kit) #2 →. YOFF-203 and Mobile HF Antenna, Proxel PRO-X1. Last weekend I did some mobile antennas experiments on the field. I have in my shack two of them, one “don’t remember brand” dual band VHF/UHF and one HF antenna, Proxel PRO-X1. Which I never use them before. The PRO-X1 is the italian version of the MFJ-1699. And the australian Outbacker. Proxel PRO-X1, HF Mobile Antenna. On SSB, called him once and for my surprise he came back ...

A ROMANIAN RADIOAMATEUR'S BLOG. YO3HJV - Ham radio related stuff. Simple oscilator for testing cristals. Yesterday I was a little bored and I was staring to a box full of quartz cristals. I was wondering what frequency was, especially a very old one with russian marks on it. I know from an elder that the number on the Russian cristal is not the frequency but some sort of code. Stupid, eh? It's a 74LS00 oscillator in series configuration, the schematics is pretty self explanatory. This scope is a nice one...

A ROMANIAN RADIOAMATEUR'S BLOG. YO3HJV - Ham radio related stuff. Hytera PD785G follow up. A few weeks ago I wrote about Hytera PD-785G as I seen it and used it. Today I have to make a follow up about things that I disliked before, things that are now history due to the recent firmware update. The FW I made is to rev. 6.05, the latest one, a firmware update that solved a lot of problems. Now, on the analog channels, the user can programm the Rx CTCSS and the Tx CTCSS, separately. From a friend of mine i ...

A ROMANIAN RADIOAMATEUR'S BLOG. YO3HJV - Ham radio related stuff. Kenwood announced the latest VHF/UHF mobile radio with APRS and Echolink functionality. Well, it's a little embarrassing because the Echolink is not the latest trick in connecting remote repeaters or radios (altough the simp[liest one) and a GPS inside the front panel is not a very complicated matter. As a fact, I done my own RC-D710G. A few years ago and it works nice! Maybe I lost a patent, who knows? Link-uri spre acest articol.

Desi imi propusesem inca de anul trecut sa dau curs invitatiei de a participa la Ham Fair, din cauza unor probleme de sanatate am fost nevoit sa lipsesc.
