OK so what is the trick to work the FM repeater on WX-1 ? Using TS-2000 and set to :
Uplink: 145.8250 MHz FM, PL 67.0 Hz. Downlink 435.6750 MHz FM I have no problem working Linear Transponder.........................
A good question. Some people seem to get in effortlessly, others seldom if at all. I fall into the seldom category, though I had better luck today. Someone suggested that perhaps my dilithium crystals needed realignment, so I pulled out my calibrated deviation meter, and verified the PL is set as recommended for the FT-847 at 700 Hz. Next, I pulled out my counter with GPS time base, and measured 66.961 Hz for the tone. I am pretty certain that an accuracy of .06% should be good enough. ;)
I am wondering if it wants significantly more or less PL audio level. It shouldn't be too hard to rig up an external injection when the operation is more frequent. You have got to love satellite ops. Always something interesting to consider!

I think that the whole problem is the sheer number of stations trying to get into the bird at the same time... destructive interference occurs between all the differently-phased PL tones, and NO ONE gets in most of the time.
I would love to see how much easier it would be to use with the tone turned off. Either that, or leave it in linear mode all the time.........

I haven't been able to get into the sat either in FM or linear. And I work AO-7 and VO-52 regularly as well as the FM birds. Frustrating so far but I will keep at it.

I have the same problem with my TS-2000. I get into all other FM sats but sure can't raise XW-1. Pete WA6WOA
