I put about 6 hours into testing the KWS-1 yesterday and another 2 today
I’ll record the important metrics here – because I can then compare these to others who have the KWS-1:
VFO INJ Test point – 600 mv Peak to Peak and 3.25 mhz with the dial tuned to 3.5 mhz
XTAL – on 40M – 4 mhz, which matches what Howard measured
6CL6 Grid – 11.6 mv and the Carrier control did change the amplitude
6CL6 Plate – 88 mv and the Carrier control did change the amplitude
6CL6 Cathode – 49.6 mv and the Carrier control did change the amplitude
Negative bias when reading off the 4X250B Grid – with one final tube pulled – 41.54 to -97.7 vdc
My readings seem in line with what Howard measured – for the most part.
The only thing that is weird is that in Tune, when I turn the Carrier control up – the oscilloscope shows the increase in amplitude of the waveform, but the Grid function of the multi-meter doesn’t show.
I do see RF out – and will practice tuning this rig up – my final test will be to tune it up to get maximum output. I can use my RF Wattmeter for this.
