Hello, I was collecting parts for a UHF Simulcast system at one time, I had collected several Quintron exciters for this purpose and kind of lost interest. I have way to much to do but I have had over 20 years in the Simulcast paging industry. The company I worked for had Quintron install the first High-speed digital paging system after it was developed by Quintron. Anybody remember Terry Carpenter from Quintron days (RIP)?
I would be willing to help anyone with a project like this, email me directly at [EMAIL PROTECTED] Thanks, Paul -----Original Message----- From: [email protected] [mailto:[EMAIL PROTECTED] Behalf Of Steve Bosshard (NU5D) Sent: Sunday, June 05, 2005 5:25 PM To: [email protected] Subject: RE: [Repeater-Builder] Simulcast: Anyone done this for ham repeaters I saw a disciplined oscillator using cdma cellular instead of gps - This would be useful in synchronizing transmitter oscillators. Ed O Conner at Simulcast Solutions has been a super helpful resource. The other half of the picture would be site voting receivers... Most ham clubs do not have the resources for a simulcast system, but it would be nice. Also a trunked 2 or 3 channel system could be viable.

Remember -frequency-phase and deviation from each transmitter is very important. Regards Bradley Glen ZS5WT --- Steve Rodgers <[EMAIL PROTECTED]> wrote: > > Thanks for all the replies.
