Blair, NF6X http://www.nf6x.net/2009/02/converter-m-209-b/#comment-149 Mark J. Blair, NF6X Mon, 20 Feb 2012 16:50:32 +0000 http://localhost/~mblair/2009/02/converter-m-209-b/#comment-149 Thanks for visiting my site! I don't know of a definite source for what you need, but here are some suggestions: 1) Set up some saved searches on eBay, because M209 machines, parts and accessories show up there occasionally. Make sure to search worldwide, because I've seen Hagelin equipment appearing from a couple of sellers in South America lately. 2) Join the <a href="http://groups.yahoo.com/group/cryptocollectors/" rel="nofollow">CryptoCollectors Group on Yahoo</a>, and ask there. Many prominent crypto gear collectors (and plenty of amateurs like me!) hang out there. Incidentally, group members have arranged a crypto symposium in the eastern US late next month: <a href="http://www.cryptosymposium.com/index.html" rel="nofollow">Charlotte International Cryptologic Symposium</a>. I don't think I'll be able to attend, but I'm sure that I'll regret missing it. Anyway, congratulations on obtaining your cipher machine, and I wish you the best of luck in repairing it and finishing out its kit! Thanks for visiting my site!

I collect US WW2 radios and have just obtained my very own M209-b which is in good condition. I too want to display it at shows as it is quite a rare item in the UK. It came almost complete except that it is missing the TM Manual , oil and ink bottles, paper roll, message clips, tweezers but most important the first rotor has a crack in it which I would like to repair (very difficult or) obtain a replacement. Do you know where I can get spares for this. I am in the UK but have friends in Kentucky that parts could be sent to if too expensive to ship to the UK best regards Kevin Chester UK Great site.

That mount can make life easy for BC-1335 collectors. Either spend a lot of money having a Chinese company manufacture some BA-70/U's, or use one of Pietro Noto's converters. The mount I have is just for the BC-1335. It has shocks, is very heavy, and until I buy an old van and have it attached to the floor or raised up on some angle brackets so it is near my hands, it will remain a curiosty.

I took another look at that set, and there was the special connector for BA-70 use, in the upper right hand corner. By the way, I tuned the radio a week ago, and earlier today I bought a 6 volt auto battery and rewired my power cord to run the set off 6 volts. It powers up and there is the rushing noise in the earplugs, but now I have no side tone when I transmit. Frustation! I think I need new glasses!

They're only used as a reference voltage for calibrating the magic eye tube, and have no other effect on the radio's operation. I just used a bench supply set to 0.4V as a reference in place of the bias cells while tuning up the radio on the bench. I haven’t replaced the bias cells in my BC-1335.

By the way, have you had success with the bias batteries? In case you are not aware, the bias batteries used back then were mercury. Nowadays, the button battery substitutes are alkaline, with reversed polarity. If you study the retainer clips, you will see that the alkaline cannot be used in the retainer, for they will not be in series. I had to remove the clip assembly and reverse the leads.

I was told that the newer BC-1335 version that worked with the dry battery box had another connector added to the front panel for the battery input, though. A Google search turned up <a HREF="http://www.greenradio.de/e_bc1335.htm" rel="nofollow">this page</a> that shows the new connector at the upper right corner of the front panel.

I have a BC-1335 that is different from any other I have seen. In the spot where the spare vibrator usually is, this one has a toggle switch with 2 positions, marked 'vibrator' and 'BA-70.' The BA-70 goes in the battery box that the BC-1335 clips on to, but the power connector on the BC-1335 has 3 conductors: negative, + 6V and +12 V, whereas the battery box connector has, I believe, 5 conductors.
