Ham Member Lookups: 8860

Hello, I am Friedhelm, or Fred, living on the outskirts of the village Karken very close to the Dutch border in JO31AC. My previous callsigns are DL7AJA, DC9PX and DC9PXA.
During daylight my station gets the complete electrical power from a 8,5 kW photovoltaic system. Also on days without direct sunlight there are enough kW from the sun to run my 8877 PA. Production per year >8500 kWh grid parallel.


Together with Hans, PD1AHM, I put my 2 m antenna, 17 ele Tonna, 13 dBD 6,6 m long, on top of the house two days ago.


Yesterday I could tune my Rohde & Schwarz SU 156 im AM for the first time. Frequencies 144,567 MHz and 144,712 MHz.

That TX is excellent for 2 m AM. Six channels with XTALs, 200 WPEP out, 24/7. See first setup in my shack:

left the Mike from Beyerdynamic, Germany, Mixer Behringer Eurorack, Germany and in the right the Rohde & Schwarz SU 156, Made in Germany.

New adress since June 2014, my new locator is JO31ac.

My DOK: G13, previously R31, previously K32

I was QRV the last years on 2 m weak signal also as:

ZA1A, VO1/DM8MM, YO5/DL7AJA, EA3/DM8MM, EA6/DM8MM, EA8/DL7AJA, EA8/DM8MM, TK/DL7AJA and from F, I, ON, PA, OE, HB9 as well.

Years ago I was the VHF/UHF/SHF manager of the DARC Distrikt "K", Rheinland-Pfalz and

I am a holder of the "Goldene Ehrennadel" of the DARC Distrikt "K", Rheinland-Pfalz, too.

In 2009 I tried to cross the Atlantic as VO1/DM8MM. Two weeks on the east coast of Newfoundland with 750 W and 13 dBD antenna, but no luck.

And this is my 2nd QTH in JO40AQ, 653 m ASL, Salzburger Kopf, in Salzburg, Westerwald:

This is a very good QTH for VHF work on a hilltop. One of my contest results a few years ago. With little effort, good success:

I am responsible for the 2 m beacon DM0DUB in JO40AQ on 144,436 MHz

I am responsible for the 70 cm beacon DB0AD in JO40AQ on 432,488 MHz

and on 6 m DB0DUB in JO31AC on 50,483 MHz
