Dear YL's and OM's,

welcome to my QRZ.COM page!

 

Common information:

I really like paper QSL cards, so if possible send me your QSL card via bureau or direct, please!
QSL cards from SWL's are also highly appreciated!
Many thanks!

I'm a member of DARC (German amateur radio club) / DOK C25, see also: ov-erding.de

 

My FTDX 1200 radio:

Most times I'm using my Yaesu FTDX 1200 transceiver together with the microphone displayed at the top of my callsign page.

The missing link of my FTDX 1200 radio - The IF interface mod:

Together with some other ham radio guys I searched for a port inside the FTDX 1200 transceiver where the 1. IF (40.455 MHz) signal can be tapped from.

We found the following solution:

The 1. IF signal can be tapped from pin 3 of the relay RL1007 on the main-unit board of the FTDX 1200:

Solder one end of a small capacitor (10 - 22 pF) to pin 3 of the relay RL1007 and the other end to the copper core of a thin coaxial cable (50 - 75 ohm impedance). The copper shield of the cable can be soldered to a ground lug and secured with the screw just adjacent to the relay.

Connect the other end of the coaxial cable to a suitable USB DVB-T stick (with a RTL2832U demodulator & R820T tuner), install your favorite SDR software for it on your PC, configure it and enjoy the live waterfall display!

Below there are two picture to show the connection inside the FTDX 1200:

Further background information about this hack can be found in the Yahoo group: "Yaesu_FTdx-1200" under the topic: "SDR Panadapter for the 1200" or you just send me an email!

 

My Elecraft KX3 radio:

I also own an Elecraft KX3 transceiver which you can see below:

 

Looking forward to meet you on the bands, mostly in SSB, sometimes in digital modes, still learning CW!
