Greetings all,
As previously reported, my softrock is dead-has to be a bone crushing+ loud signal to be heard. But, the output level to the sound card appears identical compared with my borrowed and fully functional softrock. By this I mean that both units put out the same signal level to the soundcard with no antenna connected....in fact, it's impossible to tell them apart until a decent antenna is connected.
So, I figured I had a tuned circuit problem between the antenna and the transformer...but that the power supply, the switch and the logic was probably working fine.
I borrowed an MFJ antenna analyzer (MFJ-269) and fed the thing into the antenna input.
I've checked these figures twice, got the same numbers both times.
These measurements were taken on the bench with power applied from the computer and with the connection made to the sound card (without antenna attached). I have a fairly high degree of confidence that the MFJ is in working order, it's used often and has recently made stubs for 6 meters and the numbers seem reasonable when hooked up to my 2 meter yagi.
So, here is are the results.
SWR Rs Xs
5 Mhz 15(12) 12(15) 102(96)
6 Mhz 1.7(3.2) 77(14) 26(12)
7 Mhz 3.8(2.1) 30(24) 63(12)
8 Mhz 2.7(2.4) 113(21) 56(14)
9 Mhz 1.0(5.3) 49(11) 2(25)
Has anyone else had their softrocks hooked up to an antenna analyzer? The numbers seem like they should be a little closer to each other, so I'm not sure whether to look at the tuned circuit or elsewhere. Any suggestions?
HELP!!!!!!
