So, I'm finally getting to the transmitter alignment section on K2 #5945.
With a dummy load, I set power on 40M to 2W, and go into tune mode. I can never get more than about 0.4W on the K2 display, and my wattmeter barely moves, which would jive with that also. Moving L1/L2 through their full range has no effect, the power fluctuates between 0.2 and 0.4W regardless. It's the same on all bands.
Current draw is about 0.75A in tune mode.
I had previously aligned the receiver, and the reciever was listening nicely on 40M.
Going through the troubleshooting section, I can't find any problems with the suggested troubleshooting points.
One thing that struck me as wierd, is that the two 1% resistors that Troubleshooting refers to (1.5k and 226 ohm), I think R66/67 (?) both read 195 ohms, but they are the correct color code and I confirmed that I checked them before installing. It appears strange to me because the other resistors read correctly while installed, but these do not. So, perhaps this is my problem?
Any ideas?
Thanks,
Jeff
