Thanks for looking me up in QRZ.com. A brief background about myself.

 Sydney N Smith, BChD, MChD (MFOS), PDD (Path).

I was born in Pretoria 1945.  Graduated from University of Pretoria and am a post graduate of University of Stellenbosch.  After many years (35) of practice in Cape Town as a  Maxillofacial and Oral surgeon and specialist in the UK,  I have  retired from active surgery.  I now reside in Clanwilliam, the home of Rooibos tea (Red bush tea) situated at the gateway to Namaqualand and at the foothills of the Cederberg Mountains.  My QTH overlooks the Clanwilliam dam.

I was first licenced in 2005 as M3ZAO whilst working for the NHS in the UK.  I joined the Shefford club where I obtained my foundation licence.  In 2007 I passed the Advanced course and was licenced as M0ZAR and achieved one of my lifetime dreams.

One of the first tasks I undertook was to have some form of visual historical background of the development of radio, so I started building crystal sets and ended up with the regen receivers circa 1910 to 1930's.  I love the breadboard construction and will certainly try to continue building with this style.

I recently obtained my 100 DXCC certificate from the ARRL and will be as active as possible.  I have also migrated to the digital modes and also enjoy this activity.  I have started contesting which I find most challenging and exciting. South Africa is not on the "main hi-way" regarding DX and contests I soon discovered, however I am begining to "learn the tricks of the trade".  At my age I am trying to learn morse code, however listening to DX expeditions and pile ups, I feel that I will never reach that stage of proficiency and whilst trying I will tramp on too many toes. It seems that computer generated cw used judiciously is the way to go. Any comments??

Currently I have worked 281 DX entities, Worked All Africa, Europe, WAS, Worked All Continents and WAZS.

My other hobbies are 4X4ing, amateur photography, and a  "little bit" of astronomy and hiking. I enjoy most classical music but the baroque style is my favourite and of course the 60's rock music.

QSL cards are no problem. Only direct and please include 3 green stamps with all the necessary envelope etc, but please no IRC nor any postage stamps If I receive an IRC or a foreign stamp,  I will reply via the bureau. Also do NOT write any callsign on the envelope. I also use LOTW, QRZ.com.  Please note no EQSL

I also try to abide by the DX rules.


My station details are as follows

My main rig is the Yaesu FT 950. The linear amplifier that I use with the FT 950 is the ACOM 1500.  The antennas are the Hex beam on a Tennamast at 15 meters and a dipole tuned for 40 meters at 11 meters. My secondary rig is the Yaesu FT897D, using the ACOM 1011 linear amplifier with it. I use the Heil Pro headset and  the BHI dsp noise cancelling speaker. Thatch becomes hot during the summer months, so I use multiple fans to keep the rig and amplifier cool.  Outside it can


reach 45 C +  and the shack  35 C .

I use, for logging in general, Ham Radio Deluxe version 5 with Signalink for rig control.  Contesting software is UCXlog which I find works well for me.


My mobile setup.


I use the Kenwood TS-480HX with the SGC 230 smart tuner into a 9 ft whip.  I also have various mono-band whips such as the Ham Stick,  Hustler range and a High Sierra screwdriver antenna. When parked I remove the whip and use a 10 meter fibreglass pole for a vertical antenna. I prefer the SGC tuner with whip.


Namaqualand, where my QTH is, during the flower season.

NOW to the nitty-gritty.

Here is some of my handy work.

Henley's 222 Radio circuit design number 168.


A double regen receiver made from hospital theatre parts. This was built

whilst working for the NHS and was a follow-on from the BHS crystal set.


The 1911 British General 3. Quite difficult to get the circuit diagram. Coil obtained from ebay.


The Gernsback interflex radio. A combination of a crystal set with

valve amplification. Built the Perikon detector.


The Lintophone reconstruction project. Obtained the empty box on ebay

and reconstructed it exactly to its original form.


The BHS Crystal set which appeared in the 2008 August edition of Practical Wireless

Also made from hospital theatre parts.


The AM Tx to feed the above radios. Only one or two medium wave AM stations here.


My version of the DOERLE "19" Twinplex receiver.





The MRL 1 tube all wave regen receiver.


A replica of a circa 1912 close coupler crystal set.


My version of the Atwater Kent crystal set. I would love

to own an original one!!


A Coherer and a Perikon crystal detector.


My version of the Mystery Crystal Set
