Thank you fo checking my Page here on QRZ .com .My Name is Andy,i live in South Germany near Friedrichshafen,have 2 Children age 16and 8 years( as of 2010).I am a Taining Captain for Lufthansa on the EMB 195 Fleet,most of my dutys i am involved in tainingin the aircraft or the Simulators in München .DL8DX is myCallsince 2006.06.29 .My former Call was DL3GEA.The US Call is KB9FIG issued in Springfield ILL.,i did live there from 1989-1991.As the Control Operator ofthe localUHF Repeater i am also responsible for theStation DB0FIG 438,7875 Mhz(Echolink Node 9911) ,and the APRS DIGIDB0XII.More Information of the Repeater is listed under its Call in QRZ.com.

The Rigs used for HF are : Icom 775 DSP ,Icom 781,Kennwod TS 870 S

Antennas for HF 3 Element Step- IR and a 250 Meter Longwire at 30 Meters hight .

In my new RadioroomDec 2010

The new Baby RF linear amplifier is a noncommercial Prototype ,made by a very good friend of mine .Its under test,works throughout from 1.8 MHz to 29.7 MHz and has proofed several 24 Hrs duty without heating up higher than 35 C temperature at a low noise cooling Van.All my other Amps that I had did not withstand such extreme use at all.

There are some considerations for a few changes like 2 Inputs for more than 1 Radio as we already have a build in Antenna Switch for 2 Antennas.Soon a 5 KW and a 8 KW Version could be coming up ,not to break the law in Maximum Power ,the Reason is we hear waytomany bad Signals on the Bands from AMPs that are running at their Maximum Output of 1500 Watts driven from TX with 100 Watts input to achieve the legal Output and getting totally overdriven.Check the Bands on a Contest weekend and make up your mind ,you will sure understand where we are coming from with that Opinion.If our Tests continue to be such a big succsess as it started we do plan a very small Production of individual and personalised Amplifiers.

A remote Tuner capable of 5 KW will go online here in a few days to match my 250 Meter Longwire,as all commercial Tuners on the Market failed with such a high Impedance at the Feedpoint.

It all will be in the well known German quality.
