About Myself
Welcome! My name is David, born in 1967. I live in a large town, Milton Keynes which is approximately 50 miles north of London.
I first became interested in radio during the Citizen Band radio craze and quite soon into SWL (Short Wave Listening). Amateur radio fascinated me more than CB radio but I did not become a licensed radio amateur until July 1991 as G7JYA.
In my first couple of years I was limited to 2 metres radio gear and I enjoyed working both FM and SSB voice communication. Through friends my interest was almost immediately upon Packet Radio. I continued SWL'ing and longed to be able to access HF bands.
I passed the 12wpm (words per minute) morse code test and became licensed as G0TWN from July 1993. I traded in my 2 metres base station radio for a Kenwood TS-430S HF tranceiver, which I still use today, mainly C.W. and digital modes. I quickly returned to packet radio with the purchase of a cheap 2 metres FM transceiver.
So, my interests principally are HF and digital modes. However, I am keen to branch into other areas, such as ATV, Microwave and PacSat, to name a few. Accomodation space is my
problem though, currently occupying a corner of the kitchen. : - (
I hope to put a conservatory on the rear of the house which would give me some space!
Packet Radio
I am the Sysop of GB7IMK TCP/IP packet radio BBS which has been running since December 1997, serving the Milton Keynes and North Buckinghamshire areas. At the beginning it was an enhancement to the local packet network but GB7BEN AX25 BBS has since closed. It offers users the chance to experiment with TCP/IP over packet radio where you can utilise common internet client software within MS Windows or Linux, for their access to local facilities. These include, personal mail, news (bulletins), HTTP Web Pages, World Wide Converse (WWC) and DxCluster, to name a few.
I also host and manage the United Kingdom IP groups (UKIP) website, promoting the use of TCP/IP over amateur packet radio. There is so much more that you can offer over TCP/IP than AX25 alone can offer. This may confuse you, having seen nodes such as LONNY but although such systems have AX25 users ports, as does GB7IMK, they are TCP/IP systems.
HF Radio
As I explained earlier, space is at a premium just now and so I don't use HF as much as I used to or, wish to.
The 12 w.p.m. morse test was originally just a barrier I knew I HAD to take to achieve my 'A' (Class 1) license. On my own, I admit to struggling with learning the code. I had pretty much learned all the alphabet but was struggling. I then with a few friends, Bill G0TGU and Barry G0UCK, started going to morse classes with the late Stuart G0GOF. A jovial, kind chap, who got me through within nine months.
I, like others before me, promised Stuart that I would give C.W. a try, upon getting onto HF, and I did. It originally was just a means to an end for me but once I started, I enjoyed the conversations with those I met. Not just the basic, name, QTH and 'your 59', that I was mostly finding on HF voice but, enjoyable conversations. True that they took an awfully long time but, as my speed of sending and receiving florished, I got addicted. Truely addicted. I still played voice and datacomms but my QSL card collection is mainly from the many, many great people I have met. Strange, CW operators respond to more of my cards than voice operators 'promise' to.

Other hobbies
When I'm not converting PMR for packet radio I also do a bit of programming. C, XHTML, Javascript and PHP/MySQL mostly. Yep, never found a WYSIWYG GUI to my satifaction (cheap anyway!). So all my websites are coded raw. I am updating all my websites just now. Adding Cascade Style Sheets and W3C comliance for speed.
Although not deemed such a ''black art'' these days, I also build and maintain my own computer systems, network and OS'es.
Currently MS WinXP, Linux Mandriva and Ubuntu. Running a range of servers, primarily for the radio amateur (ampr) packet radio network.
