Can some one please point me in the right direction? I am building a K1, 2 bands 3.5 and 21 MHz and have got to page 46, "Alignment and Test Part II" All resistance and voltage measurements have been within the limits. Band 1 (3.5 MHz) is working perfectly on receive and transmit with signals received at good strength and about 6 watts out on transmit. Yes, I heard a starion calling CQ when checking the receive side and could not resist answering him! so have had the first QSO. However on band 2 (21 MHz) there is no output on transmit. I think it is OK on receive, I have used my old and cheap sig. gen. and can receive the signal from it.. The 21 MHz band has been dead so I can't compare the K1 with another receiver on that band. I do have another 2 band filter board, 3.5 and 18 MHz. I have tried this board with nearly the same result, I get about 0.2 watts out on 18MHz.
I have checked the orientation of the relays, which is correct but get lost trying to follow the transmit signal path through the TR switching. Any help will be appreciated.
With thanks in anticipation,
George, G3ICO.
