Missing some "dits" and "dahs"
Locked

Hi All, After a few months delay of ignoring my K2, I finally got back to putting the audio board, keying mod and new firmware in, and have noticed what I think is a new problem for me, (not sure if it wasn't there before) When in CW mode, (have the 100 watt pa board) and I first key up, I get nothing out, seems to take about 2 to 3 dits before power comes up, after that, all is fine, If I change bands, the same thing happens, go back to the previous band, its the same, 2 to 3 dits, power comes up, have noticed, that usually on the 2 or third dit, it only comes up to maybe 20-30 watts, then full 100 watts, this does not seem normal, did I forget to turn something on ? or off ?? anybody else come across this ??? 73 de K7ZUM Ken in Gres"HAM" Ore _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

That's normal in all K2's, QRP or QRO, Ken. Unless you have a
neo-geo-gravitational flux going over on the east side of Portland that we don't have on the west side (in Forest Grove) <G>. What's happening is that the K2 power control is actually a "requested power" control. When you change the POWER knob setting, the next time you transmit the power monitoring circuit compares the RF power output with what you've requested and then adjusts the RF output to match it, assuming that it can. That's why the POWER control lets you set it for power levels above what the K2 actually produces on most bands. In order for the K2 to "know" whether to change the power output to match what you've requested, it be making RF. The logic circuits monitoring the power output are "polled" at intervals, so if you send some dits it might take several before the K2 is actually making RF long enough for the power control circuit to adjust things properly. For safety's sake, when you first turn the K2 on, the internal power control automatically sets the output to zero, so the first dit or two are sent at nearly zero watts. You can bump up the power faster after turn-on by sending a dah instead of dits.

In reply to this post by Ken K7ZUM
Thanks to all who answered my initial question about missing a few dits, and now I know that it is "normal" with an easy work around, now I'll use a single "dah" (instead of "dits") seems to bring the power up almost immediate. and btw, Ron, you would not belive what kind of weird neo-geo-gravitational wiz bang super duper electron charged flux we gots going on over here in East County !! 73 de K7ZUM Ken in Gres"HAM" Ore Hi All, After a few months delay of ignoring my K2, I finally got back to putting the audio board, keying mod and new firmware in, and have noticed what I think is a new problem for me, (not sure if it wasn't there before) When in CW mode, (have the 100 watt pa board) and I first key up, I get nothing out, seems to take about 2 to 3 dits before power comes up, after that, all is fine, If I change bands, the same thing happens, go back to the previous band, its the same, 2 to 3 dits, power comes up, have noticed, that usually on the 2 or third dit, it only comes up to maybe 20-30 watts, then full 100 watts, this does not seem normal, did I forget to turn something on ? or off ?? anybody else come across this ??? 73 de K7ZUM Ken in Gres"HAM" Ore _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.
