Thank you in advance for your help. I built a KX1, though I had it working
on 20-40 as I could receive great and made a few contacts. No idea what the
power level was. I added the 30 80 board and finally the tuner. The tuner
is showing .4 watts topps. I don't have a wattmeter, however someone showed
how to use a diode - capacitor and multimeter to get a good aproximation.
Again I am getting from .3 to .5 watts. I have done the power mod, so I
started to look at voltages. All are good except Q7 which should have a
base voltage in tune of .7 volts. I am getting a negative .7 .8 volts
depending on band. Since this transistor seems to be acting as a switch
driven by a line driver, driven by the MCU, I am wondering if it is safe to
lift a leg of the resistor feeding it and see what shows up. I am fearfull
of dumping high level rf into somewhere it shouldn't be by doing this.
Has anyone else had this problem? Looking for any help or solutions.
Thank you,
Richard KK4UFY
