Chris Rutkowski - NW6V


I've been researching Morse and Vail for some time now, and doing a presentation entitled "The CW Way of Life" at the SeaPAC Pacific Northwest Ham Convention Saturday, 1 June 2019.

Wanted to complement the author of the article about "who invented Morse Code."  Having read many, many books and recountings of the story, I find his/her analysis among the best I've seen, and it's on the reference list at the end of my PowerPoint presentation. The PowerPoint will be downloadable from the SeaPac site after the event; the author might find it of interest because I found some items in the historical record others seem to have missed, or perhaps misunderstood; sheds a bit more light on what Vail invented, when, and why. There's a section on it in the PowerPoint.

Anyway, GREAT article, and great site. Congrats to all.

I just acquired a Heathkit DX-100 that I plan on inspecting carefully before adding power slowly. Saw your site had some articles about this transmitter and am eager to read them for useful information.  After browsing your site I may wish to establish an account.  Live in the middle of Washington State in the USA and enjoy tube (valve) equipment.

Good day Howard,

The DX-100 is a stunner. I will send you an email with some details of a member who restored one a while back. Great to have you on board.

Hi all, I have recently inherited a Barlow-Wadley XCR30 Mk II radio with FM.  My FIL used it to listen to the SABC French service where he worked.  The FM works very well but I cannot get any signal on HF AM.  The aerial was broken off long ago but he used a piece of wire that I can remember.

I was trained as an RAF engine fitter (nothing to do with radio) but worked on a AW Argosy E1 which took me around the Far East, Singapore, HK etc.  I remember it had a big RACAL RA17 radio downstairs and we used it to get time signals - Hawaii if I remember.  The radio was used to check the frequencies used by ATC which were often slightly out.  I read that this radio also used the Wadley circuit.  This was in 1968/9. 

Later here in SA I got a JRC 505 radio which was terrific when used with a home-made antenna tuner.  Unfortunately it was stolen in a burglary many moons ago.  For years the only SW radio I had was a little Sangean analog receiver used for the BBC news originally during the Falklands war as there was nothing on the SABC and no internet news then!

I found your website while looking for a copy of the Transistors-for-the-home-constructor book, which I owned as a kid in NZ c. 1961, and which got lost somewhere along the way. Only I think it was Volume 2. Perhaps you could help me clarify which? My copy included a project to build a Geiger Counter based on a one-transistor blocking-oscillator DC-DC converter (with home-wound Ferroxcube pot-core transformer) and Philips GM tube. It worked well for years until the GM tube quit. I am actually trying to find the schematic and other details of that article. I received help from G Zimmer on who, after a couple of false leads pointed me to your website.  Thank you for the work you've put into your website. Very useful. I live a long way from NZ now, in the Pacific NW. I used to have a New Zealand ham call sign, but now have AJ4RF (which originated in Florida, hence the '4'). 73, Al Roxburgh, AJ4RF

I hope you are able to download it and get the answers you are looking for.

A yes.   All I have ever had was antique gear, as the new stuff was too expensive.  After a lifetime having little time for amateur radio. and always having more professional radio stuff to do than time would allow, I now find myself in South Africa doing almost nothing, and little radio gear nearby.   Yes, I will have to light up that water tower.  No, I have no web site, though my current licensed commercial broadcast station (leased to a friend) can be found by searching KNIK-FM.   And I did piece KNIK together from equipment found here and there.  I am suffering from RF withdrawal symptoms and hope to correct that situation soon.  No tower should go to waste.  Not even the water tower.

The Western Electric transmitter found on the above link is quite like one I used at the FM station in St. Louis Mo.   Lots of tubes, both little and large.

I look forward to meeting some of you one day.

Good evening - I was just surfing around on the Internet and found your website by accident - a most interesting site from several aspects. Firstly the section on old receivers - I had quite a few of them so it recalled some fond memories. What I found more remarkable is that I was the last astronomer to live at 18a Gill Street in what is now SAIEE house!. I was employed by the then Republic Observatory and around 1970 to 1973 my wife and I and children lived in the double story mansion. At that time I was not a radio amateur -only becoming one about 1974 or so but a lot of amateur radio was done as I used to track artificial earth satellites by means of their radio transmissions so had a variety of antennas in the spacious yard as well as a large 137 Mhz array on the roof of what was then the main Observatory offices which I used for reception of weather satellite pictures. In addition two of the rooms in 18a Gill Street were full of radio equipment - I even burnt one of the floors with a hot soldering iron (by accident)! Anyway nice to see the house being put to good use - I miss those days!

Best wishes, Greg Roberts ZS1BI.

Hi Greg.
This is most interesting! We would love for you to come around once the museum is up and running. The SAIEE has built new offices on the premises, and allocated the entire house to become a museum dedicated to communication. What a beautiful place, I can just imagine how pleasurable it must have been to reside there! The first room contains telephone equipment, and we are now busy installing the radio room in what used to be the kitchen. Richard ZS6TF is slaving away getting the SAIEE collection sorted, categorized, and ready for display. He is also in the process of installing a beam antenna on the hill between the house and the observatory, and we are planning on running the museum shack on select days. More details on the museum shack to be found here, as well as links to some photos of our show-day in the radio room... the photos of the premises should bring some good memories. We are so glad you came across our site and made contact, and look forward to welcoming you back to your old residence! Please let us know when you visit Jo'burg, and feel free to sign up for our newsletter to receive updates on the museum, and hope you'll continue to check back on the site for forthcoming info.
