Story from John Cliff, GØWXU

I have just visited your QRZ page and noticed you used to be WB6GBT. I wonder if you knew an old acquaintance of mine from 1968. A guy named Wes Louden. He was a WB6. I do not remember the rest of his call. I use to speak to Wes on 20m from the Garrison club station 9M2RH at Malacca in Malaysia. He had heard me in QSO with Tom – HS3TM, who he could not call due to security at that period. I was able to speak to Toms father who was in the same predicament due to Vietnam. Well one day Tom announced that he and his wife were coming over to see us all at the club. Like yea we all just hop on a plane and fly a few thousand miles to go and see some friends. We took it with a pinch of salt I suppose. A few days later I got the urgent call from the Battalion Signals officer telling me that Major Salisbury requested my presence down at the Ham club like ASAP, Wes Louden was on his way. No one with any sense would argue with Bob. He was the Garrison housing officer. All club members were called down to the shack to prepare for Wes and his lady arriving. Wes had persuaded the aircraft pilot who was controlling the plane to let him speak to the tower controller at Terendak air strip, who was one of our club, to let him know that they would be landing at Malacca airport shortly. It was a brilliant time for all. Wes was able to talk to Tom. Both he and his wife and all of us were taken on a Garrison tour of the Officers Messes. They met the Brigadier and his lady, all due to Bob. I was invited to call on Wes any time that I wanted to go over but never got round to it. Unfortunately I lost contact with moving about in the army .73 de John – G0WXU.

TenTec Jupiter CW/keyboard Keyer Prosigns

Per request of Dale Mason, here are the prosigns I found available to you when you plug a keyboard into the back of the updated TenTec Jupiter for CW mode. The overline (e.g., BT), means the characters are run together with no space in between.


Name of punctuation CW Keyboard key to use
Break, em-dash, or thought separator BT  • • •  + (on numeric keypad)
End of message AR •  •  • + (on main keyboard)
Wait AS •  • • •  * (asterisk)
Short dash, en-dash  • • • •  – (hyphen)
Forward slash; virgule  • • —  / (forward slash on main keyboard or keypad)
Question Mark IMI • •   • • ? (shift-slash on main keyboard)
Comma   • •    , (comma)
@ symbol (as used in email) •   •  • ~ (tilde)
Separation Sign, as between numbers and fractions •  • •  [ (opening bracket)
Semicolon  •  •  • : (colon, shift-semicolon)

I never found entries for the common prosigns KN (go-only), SK (end of contact), or EEEEEEEE (error).
