Hey guys, I'm going to finish my KAT2 tonight and I need to calibrate the
power and all that stuff. I have a 50 ohm dummy load so the SWR cal is good
but I dont have a power meter. Can I use the RF probe that was made during
the construction of the K2? If so, is there some documentation
Tom,
Yes, you can use the RF probe. It *should* be OK up to a max of 20
watts measuring across a 50 ohm dummy load. The 1N34A diode is rated at
45 volts peak reverse voltage, so if you exceed 30 volts RMS (the RF
Probe reads in RMS volts), you are nearing the limit.
The accuracy of your
Thanks Don - My dummy load showed a 1:1 SWR on 40m with my last radio, but I
have not used an analyzer to look at it. I suspect I'll be close enough
(or at least I hope it is!) I think you are supposed to do the cal at 5
watts so no worries exceeding the power on the probe.
