No output on CW with K3
Locked
 
|
My K3 using 4.22 will put out full power in TUNE position. The ATU
works fine and delivers 1:1 swr or close. However, if I switch to CW I get zero power out. I switched to 5 watts out and still no power out on cw. I hear the sidetone as I key and the radio appears to go into transmit mode because the RX is muted. RX is fine. These conditions are the same on all bands 160-10. Switching to RTTY FSK D or PSK D I do get full power out. AFSK A also works fine. Suggestions?? Firmware issue or hardware problem? Naturally this happened in the middle of a contest!

Naturally this happened in the middle of a contest! Is the VOX text showing on the display to the immediate right of the RF power meter? If not hold VOX (left end of the band switch).

Had some funny business on 160M with K3 power.
On 1842 +/- a KHz or two the output went to zero. It was OK elsewhere in the band. Redid the TX gain calibration and the problem went away. However, I know the TX gain calibration had been done after the install of V4.22.

Check these two things first...
Do you have the rig set in test mode? If you do the K3 won't TX in any mode. Do you have the VOX turned on? The K3 will not TX in CW mode without the VOX engaged. 73, Tom Childers Radio Amateur N5GE Licensed since 1976 QCWA Member 35102 ARRL Life Member On Sat, 04 Dec 2010 14:33:39 +0000, K4GM- George <[hidden email]> wrote: >My K3 using 4.22 will put out full power in TUNE position.

The YCCCN Remote OPs group (VY1AAA) uses the K3S at this site (VY1JA) and
reported the same problem but only on Six meters. The K3s is working perfectly on all other bands. It has been confirmed that the CONFIG does not redirect TX output and tests on TUNE show good output on 6 and low antenna SWR there. As soon as this unit is switched to CW on 6 and keyed, there is no output. Next troubleshooting steps for getting this GG for the RemoteOps?

Make sure BOX is ON on all bands.
Make sure not in TEST mode on bands with no CW out.
