Had a quick check with my K2 serial No.4168 for birdies:
All 80m frequencies quoted below 4000 nothing on any mode. I did have moving
interference with a poor tone on 3857 of S1 drifting HF + a broadcast
station on 3891 of S0. Appear to be external pickup despite having a BNC 1/2W
term
on the K2 antenna socket.
4000 Yes at S1
7000 Yes at S0
10170 Yes on CW at 10172.4 at S0
LSB at 10172.5 at S0
USB clear
14171 Yes on 14172 CW/LSB at S0
14167 USB at S0
14350 Yes on CW transit only 14351.19 to 14351.20
LSB transit only 14351.38 to 14351.39
USB transit only 14353.38 to 14353.39
14361 Yes on CW transit only 14361.19 to 14361.20
LSB appears abruptly 14361.40 and disappears same. S7
USB appears abruptly 14363.38 and disappears same. S7
18172 Yes on 18172.40 CW at S0
18172.50 LSB at S0
18167 USB at S0
28000 Yes on all modes at S0
28277 Yes on CW 28275.80 at S0
LSB 28277.70 at S0
USB 28275.60 at S0
29483 Yes on CW 29480 at S0
LSB clear
USB 29481.40 at S0
All measurements were taken with the pre-amp on. Apart from the strong
birdie at 14361 of S7 and the internal 4000kHz clock in the K2, all were very
weak
and failing to move the S meter.
I think if you scrutinise most radios for the amateur market you will find
such slight imperfections somewhere, though I would suspect that the K2 is a
lot better than some. At the end of the day with all such items it is a
trade-off between the cost the consumer is willing to pay against perfection
at any
price.
