Bill,

have you checked that all cables are seated firmly? Pay attention the 
connectors need some pressing to make good contact. Also check the small 
coax (TRV to SMA) for continuity. Is that okay? Elsewise it might also 
be the final transistor has gone south. Contact Elecraft support to 
check, they will certainly guide you through a few measurements to 
locate the error and take according measures. GL!

The power control displays 3 watts but the 'tune' mode displays .1 watt (?).    CW, FM, SSB RF does not register on the VHF SWR/Power meter (10 watt setting) however I can hear my CW/FM/SSB signal in a nearby receiver.  Receive works fine and all modes on HF work fine.  I'm anxious to get this going for the VHF contest.
