[App_rpt-users] Simulcast buffer value issue

[Jeff Carrier]

I'm running the same GPSDO's without the 9.6 mhz mod to the rtcm.  The
stations are GE MIII's and the transmitter is locked to the GPSDO.

Hayden, your issue sounds more like a network or buffer issue.  I've
not ever experienced the issue you describe, even when I had non
matching TX buffer values at the 3 sites.  I'd have to read back
through the thread to see how your sites are connected.  It's
certainly a strange issue.

I didn't mean to steer this off topic from your original post and I
apologize for that.  There aren't a lot of folks simulcasting so it's
interesting to hear all the different woes.  I was always told it
wouldn't be easy!

Very good, Hayden. Yes, I've been in touch with  Joe about his project from
when he ordered the RTCMs. I was inquiring as to what Jeff was running.
Didn't mean to veer off topic.
