Hello and Good day from the Czech Republic

Hi,
My real name is Ondřej and I am 17 years old, but for radio purposes I removed the diactitical characters (which can't be spelled) and transfer my name to English name - Andrew. I'm doing radio transmissions for 6 years and wanted to became a licenced radio operator in 2008, but I gave it up and went off from all public bands for a while. In fact, there are a lot of stations in nearby area even in public bands, but they are not so friendly. So I focused on another radio hobby which is Amateur Radio Astronomy. I have acquired cheap HF receiver and build my own antenna and now I listen to quasars, pulsars and other stuff in the universe. Most HAMs in nearby area (I have listened to them on repeaters) focused only to MAKE the QSO and check "passed" in their records. I didn't want to speak to them. Instead of quantity, I focused on quality. I started to upgrade signal path to F3 modulator, bought high quality microphone, extend frequency response from 3kHz to 8kHz (14kHz peak), gold-plated cables, equalizers, mixing consoles, preamps, effect processors and I also thought about stereo or multiplexed stereo transmissions. But who from the people in public bands can appreciate this? So I used my equipment to set up a small home recording studio and leave the transceiver in drawer. Nowadays I'm using my equipment in HamSphere, still trying to focus on sound quality. However my setup is fully battery powered, so I need from time to time recharge the batteries. After all, in present tense, I don't want quantity (logs). Instead of that, I want friendly QSOs with or without parameters (report, QRN, output power, location, TRX, etc. - these are not important for me). What is important, that we understand each other and that we can share our ideas and spread our friendship. Technical nitty-gritty is the other side, no matter, we hear each other, we made QSO, we did it. However if I want to upgrade something, I upgrade the audio path and microphones first, then amplifiers or antenas. Hope you are not tired when reading this :) Andrew |

If you used the equipment to optimise your audio within the bandwidth allocated the effect would be noticed and appreciated by those who heard it. Trying to expand the bandwidth is pointless, especially into stereo, as transceivers are not designed to deal with this, it causes interference and is contrary to the licensing conditions so we have to be inventive and adaptive.. I apply studio and broadcast audio techniques and equipment to my amateur radio transmissions in order to improve both the quality and readability of my signals. I have had some excellent feedback and have developed my system and it resembles a broadcast studio when fully implemented. This includes large diaphragm condenser mic, vocal processor, multi-band EQ, Compressor/limiter, mixing desk, broadcast processor (AM settings), pro audio cards, etc etc. The end effect is worth it you have the time and patience, and most importantly the budget - it can be done cheaply if you look around and buy used kit.
