The relays mod work very well. Change only KT 1/2/3 . The filter mod looses power so skip and reduce your drive and that will keep the spurs down. Raj At 29-10-18, you wrote:
Made my first ubitx contacts this weekend - wow. It does CW nicely with straight key, with reception via NESCAF audio filter. did some SSB in CQWW - worked 23 or more countries. transmit audio seems to be effective, so maybe this rig doesn't need a speech processor after all. doing a group build - 23 total rigs. some have been measured for spurious - and clearly are not in compliance. we will be modifying each one with added relays and a 45 MHz filter stage - this fix does bring them into compliance. This rig was so much fun to operate, I wasn't tempted by the other rigs in the shack as I just wanted to have a little operating fun. 73 Curt |
