Some info about the XYL with the deep voice
Etwas über die XYL mit den tiefen Stimme...

Despite the deep voice I am not an OM, but a YL even if with my age I am a quite old XYL, probably an XXXYL and have been around in various forms of radio since the mid 1960s.

From July 2009 (for my Passport)

Due to my deep voice, for some it is difficult to identify the gender behind the Mic. Also having a Call Sign starting with “Delta Golf One Pappa....” does not help either, lol (hi hi).

I am a UK Citizen (and as you can tell from my Call Sign living in Germany). I was a member of the UK forces, serving with the Royal Signals in the early 1970s and first came to Germany when I was sixteen and half.

For those not sure what the abbreviations OM, YL and XYL mean, in years gone by, when every letter had to be tapped out on a Morse key, the radio operators reverted to shortening everything they could, much like users of text messaging services on their cellular (mobile) phones today do... Many codes are prescribed, such as the Q-Codes and Z-Codes. but in the Ham radio world, even when spoken, they also have a few short codes like the use of XYL above...

OM is short for Old Man

YL is short for Young Lady (in pre political correctness “Miss” or available for marriage)

XYL is short for Ex-Young Lady (or “Mrs”, Married and so keep them Morse tapers of her!)

Others used on these pages are;
DARC (Deutsche/German Amateur Radio Club, similar to the UK’s RSGB)
RSGB (Radio Society of Great Britain)
QTH (Home or Station Location)
QSO (The actual Contact or “Chat” with someone)
QSL (The Logging Entry in the Log-book and

My QTH is in Neu-Isenburg on the city border of Frankfurt/main, just seven Km, or four and half miles to the south of Frankfurt city centre in the Rhein Main area of Hesse Germany.

8° 42’ East / 50° 3’ North or in new form 8.70 E. 50.05 N.

I am British. Born in the South English part of the UK in the 1950s , but have strong connections into the other parts of the UK.

My Parents were both born in Northern Ireland. My Father came to England in the 1940s to volunteer (Irish citizens were exempt from call up) to serve in the Royal Engineers. Later he worked in the Diplomatic Service in North Africa (Egypt) until getting thrown out with the rest of the British in the early 1950s.

All four of my Grandparents were from Scotland, having moved to Belfast with the Shipbuilding industry from the Scottish Clydeside.

Great Grandparents originated in part from the Caithness area and Ayrshire areas of Scotland and also a branch from Wales.

I was married for nearly 30 years (Divorced five years ago) and have a grown up son...

The Divorce and my moving out, or rather me and him both moving out of my ex’s home town (my son later than me), allowed me to restart my hobby (Amateur Radio) and re-take the licence. Over the years I have been trying to recover some of the radios and equipment I lost when I had to leave my home in a hurry (For my safety and sanity).

Unfortunately my current QTH is too small and restricted to put up any decent antennas, so activities are very limited.

I am a Professional Engineer (Dipl.-Ing.) and a consultant to the Telecommunications Industry.

I specialise in change management, including my own important project in this direction some 12 years ago... and am now freelance.

I was a Design engineer for Television and Radio Studio equipment, broadcast and transmission systems, commercial and military satellite systems, cryptographic and military radio systems, weapons systems and telephone equipment and large scale Telecommunications networks.

In the last few years I have specialised more in the direction of LE/LI, counter-espionage, legal issues and protections, as well as licencing rights and issues for large multinational telecommunication and media companies.
