K2 CW TEST mode
Locked
 
|
I need to practice CW (sending as well as receiving) so I can upgrade
my license. Is it harmful to practice CW using my K2 in CW TEST mode? I would like to get use to the keyer and my paddles and not have to buy practice oscillator and keyer. _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Matt:
Ron's right, but if you plan to do this a lot, I think I'd attach a dummy load to the radio and turn down the power. That way, the finals will be protected in case you forget to switch to TEST mode some time.

This is especially good advice since the radio doesn't remember that it was in test mode when it is turned off. -- 73, Brian VE7NGR _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Thanks everyone. Dummy load is attached and practice has commenced.
I'm really surprised at how quickly I can duplicate the sounds of each letter using the paddle and keyer. It must be much more difficult to get the timing correct with a straight key.

Absolutely! You need to pass a morse code test to operate HF. You don't need to pass a morse code test to operate morse code. _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

I've just finished building K2 #4973 so the XV50 would be my first
choice. On Sat, 02 Jul 2005 20:56:50 -0300, Brian Mury <[hidden email]> wrote: >On Sat, 2005-07-02 at 18:48 -0500, Matt Osborn wrote: >> Alright!

For the KX1 just tune outside the ham bands by a few KHz. The unit won't
transmit but the sidetone oscillator still operates. Seems to work great for a little CW practice. (Some of us need a LOT of CW practice.) Grif, KF4JG ----- Original Message ----- From: "John R.

If think the transmitter is also disabled when you edit the CW speed (so that the current WPM value is displayed). No, no harm in keying the K2 in "CW test" mode -- that's what it's there for. Great feature on both rigs, by the way. --Andrew _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Hi all,
I noticed that after doing the mods to upgrade K2 #402, I don't get any output on 17 and 15 meters. I did change C30 and C36 to 470 uF, ,and C33 to 2.2 uF, which is part of the 17/15 meter band pass filter mod change. However, receive seems fine. I just get zero Watts out in transmit. Since I think the low pass and bandpass filters are shared in receive and transmit, I don't think its the filters. I wonder if a relay went bad. Any suggestions?

Stephen,
An important thing to remember here is 'IT WORKED BEFORE' - and you certainly did not change any relays as part of the upgrade. If you had adequate power out before making the changes to the 17/15 meter bandpass, look there firstly and mostly. You did not touch the Low Pass Filters by doing the upgrade, so it should still be just fine. Possibilities -- C33 was damaged when it was installed - if you just pushed it into the holes (spaced wider than the capacitor leads), you could have broken one of the leads inside the cap, and it will not show physically. Check and recheck for any solder bridges. Do you find a nice peak on receive for each inductor on 15 meters (and each capacitor on 17) - if you find good peaks, the inductors and C30 and C36 are likely OK, but C33 is still suspect (replace it temporarily with a close value to check). Use a 'scope or RF Probe to measure the RF Voltages as indicated in the Transmitter Signal Tracing section of the Troubleshooting Appendix in the manual. Find out in which stage or section the RF signal gets lost and look in that area only. Comparing the RF levels with those on a working band is a quick and easy way to determine what the proper level should be (there may be some varition due to internal gain differences from band to band). Again, I repeat, do not monkey with stuff until you find out where the signal is getting lost and look most carefully at the areas you just changed - remember that it did work before. 73, Don W3FPR > -----Original Message----- > > I noticed that after doing the mods to upgrade K2 #402, I don't get any > output on 17 and 15 meters. > > I did change C30 and C36 to 470 uF, ,and C33 to 2.2 uF, which is part of > the 17/15 meter band pass filter mod change. > > However, receive seems fine.

I'm in the habit of switching my K2 to TEST mode whenever it's turned on but
I'm not operating. That avoids becoming a dreaded 'ditter' if something bumps the key. Because I use 'phones 99% of the time, the sidetone can't protect me if I don't have them on my head.

I got a laugh the other day when he actually said, as I sat down at my desk ready to operate, "hey Daddy, the K2 is not in test mode." Sure enough... These four year olds know way more than we assume. .. _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.
