TX Factor 23 is here!

If you have never seen these video's you should !!

TXFACTOR is a very high quality youtube-channel and companion website fully dedicated to Ham Radio.
The video's these guy's make are absolutely professional grade !!

Unlike some other videoblog's that produce a ton of video's on a regular basis but that are often barely watchable because they are so poorly made,
TXFACTOR doesn't creates video's that often but these are episodes that just as well could be transmitted as a program on the big TV broadcasters.

Arduino CTCSS single frequency


Some time ago I've published an article how to build a CTCSS encoder using an Arduino.

Now I've receive a question from Konstantinos, SV1ONW where the answer might interest other people too.

He wanted to use the CTCSS encoder in their local repeater, but for this only a single tone is required,
and to avoid the need to select the correct tone with the up/down push-buttons he asked me if it was
possible to have the encoder produce a single tone only.

QO-100 - uplink good practice

Activity on the first geo-stationary Ham-Radio satellite is full swing now !!

It's nice to see how power levels of as low as a few 100 mW with a cheap consumer satellite dish are sufficient for a transmission distance of 36.000 km ...

Several homebrew hardware projects are now also showing up and one of them is "POTY" a Dualband feed one can mount on a consumer dish.
This feed combines a 2.4 GHz right-hand circular uplink with a 10 GHz Horizontal downlink.
