[WT-support] Speed jumps up occasionally

Tue Nov 30 22:12:51 CET 2010

same problem @ E7DX
using MKII or MK2R+ 
was  same also with older WT versions!

  I noticed that CW speed was jumping only after I logged 3-4 QSOs per minute for a few minutes in a row.
  I didn't look too deep into WT setup @ VE3EJ station and assumed that this was some kind of "smart" feature helping to handle pile-up more effectively. It didn't bother me too much because every next transmition was back to normal speed.
  Hope it'll help to figure out the cause of this phenomena.

    I assume you use a lot of "+++" and "---" in your scripts?  Which WinKey chip version are you using?  (Win-Test reports WK Version detected it at start-up at the bottom of the logging window).

    The last time I looked at a WinKey communications log, which you can produce using the microHAM Router [SET] button next to the Winkey port, I saw that Win-Test can sometimes issue [Cancel Buffered Speed Change] commands (1E) between every letter sent.

    According to a private note from K1EL, copied to Oliver and Laurent last January:

    "All the buffered speed cancels are troubling, the application should keep track of speed changes and only issue commands when they are really warranted. While WKUSB is able to handle them it chews up a ton of CPU bandwidth to constantly invoke all the math calls that are required."

    So there could indeed be a problem with the way Win-Test is sending commands to the WinKey.

    BTW, using "+++" and "---" will usually make it somewhat harder for CW Skimmers to figure out your code speed and your callsign.  I've decided not to use them any more and I've had no issues with WinKey speed jumps.

      Hi Bob and folks,

      hmm... I didn't touch the CW speed knob on my MK2 at all during the contest. Just used ALT-F9/F10 and the ++ and -- commands in the WT CW messages, but every now and then, the ++ AND(!) the consecutive -- was ignored by WT or WK or MK2 or whatever... it just stayed at the original speed. And then, for the next couple of messages, it was doing as designed, just till it failed again. Speed pot min setting for WK inside the MicroHam Device Router is 15, max is 40, and in WT I used speeds from around 25 to 35 wpm. So this was well within the bounds, thus it should have been OK, according to your suggestion, Bob.

      I have tried the "CW message and paddle speeds" both set to "Independent" or "Synchronized", and the speed settings set to both "Only by the WinKey pot" or "Only by the WT commands...", and it occurs in each of those settings.

      I know, that is somewhat different to George's problem, but our effects may have a common cause.

      Using WT 4.7.0-dev Rev. 458 and MicroHAM Device Router 7.7.1.

        See this post for some history about this issue. 

        Bottom line, Win-Test assumes a speed pot range of 20 WPM to 60 WPM.  If you use any other ranges, the speeds can get out of sync.  When you change speed with Win-Test, the POT does not move to track the new speed, so its position is immediately out of sync.  Slightly touching it or some other vibration might cause a resync to pot speed, and a speed jump.

        All WinKey / Win-Test speed jump issues go away if you forget about touching the speed knob and only use Win-Test to change speeds, that is, use "the only by the Win-Test commands" option in Options | Winkey configuration .

          Here is a question for both the WT and Microham support reflectors:

          I find that occasionally the speed will jump up many wpm when I send a "TU K5KG" message from the "+" key.  I will be running and running, and sending TU K5KG with the + key QSO after QSO.  Then, every now and then, when I send TU K5KG from the + key, the speed will jump up to lightning fast (maybe 50 wpm).  I'd appreciate any ideas as to why this happens, and what to do to prevent it.

          Here is my current set up:  Microham CW Keyer, WinTest 4.6, K3.  Although, this is my current set up, the speed jump up also happened with WT 3.n and an Icom Pro3.  Bottom line, it has been happening for several years.  The common elements seem to be WT and the CW Keyer.
