KPH Crypto Broadcast Scheduled 7/22/2023 @20:00z

-

The Maritime Radio Historical Society (MRHS) will host a Crypto Transmission from KPH for intercept operators to decrypt using the Enigma Machine, or in my case a simulator.    Award certificates will be available for anyone who intercepts the message and submits the decrypted message within 72 hours of broadcast.

KPH will be transmitting the message of the day today at 20:00z, using an actual message sent by a U-boat in the North Atlantic in 1942.   Posted CW frequencies for the transmission are 6477.5, 8642.0, 12808.5, 17016.8, and 22477.5.  Messages will be repeated, then transmitted 15 minutes later via RTTY at 6324.5, 8427.0 and 12585.5.

I've prepared to listen and copy!   I've set up and successfully tested my virtual Enigma machine to decrypt the test message using Armee Stabs Maschinenschlussel Nr. 28 (Army Staffs Machine Key No. 28) key sheet for October 31, 1944.

Remote CW with RKI 1.05 and Sparkfun FT231X breakout board

I've created a workable solution for sending CW via a "straight key" to my remote Flexradio 6600 at the lake using RemoteKeyerInterface (RKI) and a simple Serial/USB circuit.   RKI is only available for Windows. RKI enables you to use paddles or a straight key to send CW through a remote Flex‑6000 transceiver.  After several iterations I've settled on a design using the Sparkfun FT-231x breakout board and RKI v1.05 that was originally posted by Gary KT7AZ on the RKI  groups.io forum .   However, to send CW reliably via a straight key - there were two main problems I had to solve. First,  I had to resolve the network latency and buffer bloat in my shack's network by setting up a router with Smart Queue Management.   The Ubiquity EdgeRouter  was recommended by a friend of mine (Larry N1FG) and has been working great.  I'm using the 4 port Edgerouter X which was only $50 at microcenter (open box special).  No more audio stuttering or dropped packets, which kills

Update 11/19/23 - Tribute for Bill Crane, SK 10/26/23: https://youtu.be/Znyqq9f93r0?si=bxPV0zVmGN7oWo_u ++ Update August 22, 2022.   I was able to find Bill Crane W9ZN on the air by looking for his spots on RBN .   Took me a while to see the pattern on when and where he's be on frequency, but not only did we make the QSO, we exchanged cards as well!  This is one of my favorite QSL cards that I've collected so far.  Thank You Bill!     73 Chris de WX7V ==================================== Last month I asked a members of the Straight Key Century Club  what was their favorite way to warm up before sending morse code.  I got a lot of input - from, "Just jump right in" to sending the Alphabet and the Numbers 0-9.   My favorite answer is to practice sending Bens Best Bent Wire, with the letters and numbers run together so that the code produced sounds similar to a march.  Apparently this was taught by the RAF,  merchant marines, and subsequently used by many commercial CW o

 Love my Wolf Rive Coil Antenna for POTA use but I haven’t marked it up (yet) to facilitate quick band changes while out in the field.   Here are some notes to use as a starting point based on the work by W0DHZ Dale Henninger: 102″ Telescoping Whip Band Whip Length Coil Position 6m Only 1st section of whip extended No Clicks – Top of Coil 10m 3 sections out + 6″ of 4th section No Clicks – Top of Coil 40m All sections out 3 Fingers Down 213″ Telescoping Whip Band Whip Length Coil Position 10m 8 sections out + 1″ of 9th section No Clicks – Top of Coil 20m 9 sections out + 13″ of 10th section No Clicks – Top of Coil 40m All sections extended 16 clicks down Reminder to subtract the length of the Wolf River Coils SB-1000 coil from the 1/4 Wave lengths above. http://www.w0dhz.com/wp-content/uploads/2021/08/WolfRiver-SB1000-213inWhip-Tuning-Spreadsheet.pdf
