I love the great feel of the key and best of all, because of the enclosure, I never have to clean the key contacts! It's my second most favorite straight key after my J.H. Bunnell CJB26003A Navy Flameproof I purchased from J.H. Bunnell Co.Telegraph Apparatus in Kings Park, NY (NOS)=New Old Stock that is mounted on a 1/2 inch (1.27 Cm) thick steel base that was custom made for me, with the screw holes tapped and threaded) by W4CUX Bill Worley, SKCC # 5497T, before his tragic death on December 28, 2012 from pancreatic cancer. Thanks for writing this very informative article about the RM-31! Mine has the later 2 prong plug on it. Very 73 from KU4GW Cliff, SKCC # 652C.

I just ordered one of these from the Czech Republic and wondered how long it will last. Everyone seems to like the feel of it (4.9 star average reviews on www.eham.net) and it looks to be better made than one I almost bought from Bulgaria (also a military key).

You are really lucky as the 4-plugs version of the key comes to be a really hard to find on the flea markets...<br /><br />It is great way how to switching the TX/RX of any TRX simply by key itself without necessity of the PTT foot switch or so.<br /><br />More often the 2-plugs version can be reachable where the only TX pins are used. It was used in RM31-M-a or RM31-M-s-p radio setups coded name Trinec where the RS-41 transmitter has been keyed separately.<br /><br />Enjoy this blog my friend.<br /><br />73 - Petr, OK1RPPetr, OK1RPhttps://www.blogger.com/profile/11092364724802787693noreply@blogger.comtag:blogger.com,1999:blog-2443470820699486974.post-28263407883960472022012-01-17T20:14:14.611-08:002012-01-17T20:14:14.611-08:00Hi Petr.

Solid and with superb quality. Will last for many many years of use and abuse.<br />Mine has a 4 lead connector. As you mentioned 2 are only active when transmitting and 2 when receiving (lever up).<br />The leads have different thickness so the key can only be inserted one way in the transmitter.<br /><br />The operating knob has got a very pleasant shape for the fingers and it sits at the right height on the desk. You can transmit for hours and not feeling tired.<br /><br />Thanks for sharing this info. I have learned a lot about my RM-31 CW/Morse key from this blog. This key and the Baumuster T1 are my favorite CW Keys. <br /><br />73 - Rob, YS1RSRobertohttps://www.blogger.com/profile/15810686867233962254noreply@blogger.comtag:blogger.com,1999:blog-2443470820699486974.post-69111559246500084312011-03-07T07:05:18.029-08:002011-03-07T07:05:18.029-08:00Hello,

You are maybe only one who is actively using RM31-M-a coded name Trinec on the air. I will try to post more articles in english but be patient as it will take time.<br /><br />I hope we will have chance to make QSO using Your Trinec and my RM31-a coded name SuperTana setups on 80m band. It must be during good condition as the power output is only 6W on my side.<br /><br />Good luck,<br /><br />73 - Petr, OK1RPPetr, OK1RPhttps://www.blogger.com/profile/11092364724802787693noreply@blogger.comtag:blogger.com,1999:blog-2443470820699486974.post-14952191408496415532011-02-27T17:07:26.297-08:002011-02-27T17:07:26.297-08:00Thanks for starting this blog, Petr.

Here is the photo of my RM 31-M-a station as set up in my shack: http://ws19ops.com/Radios/Czech%20RM-31Ma.JPG . I love to use the station and it's on the air at least twice a week!Meir WF2Uhttps://www.blogger.com/profile/17531141232121892239noreply@blogger.com
