RE: [DSTAR_DIGITAL] D-Star simplex frequency
Bruce, I dont think there is enough use of D*STAR here in Denver yet to dictate our users shifting to simplex use unless were on an operation and in close proximity of other users. We do already have a suggested simplex matrix in Denver not only for D*STAR VHF UHF but also working channels for various ARES Districts in the Denver Metro Area. Were using 145.670MHZ DV for VHF Calling and 146.505MHz Interoperation Were using 446.100MHZ DV for UHF Calling and 445.950MHz Interoperation Then we have 4 VHF and 4 UHF Simplex frequencies set up for ARES Districts in our FEMA North Central Region. To my understanding this helpful list was set up by one of our first D*STAR advocates Randy NQ0R which is very familiar with radio communications in our region and made a best effort not to assign frequencies already used for other groups like PACKET and Simplex Analog Voice. I am not understanding why a D*STAR user would not be hearing analog users unless they turned of FM DET on their D*STAR radios. It should be detecting an analog signal while in DV mode and switch your DV mode to FM Narrow while receiving the signal. On the other hand if an analog user hears a hiss intermittently breaking squelch they should over time become familiar with other shared services on the air much like we do on HF! 73 Barry Wilson KA0BBQ From: dstar_digital@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of bruce mallon Sent: Thursday, November 13, 2008 10:23 AM To: dstar_digital@yahoogroups.com Subject: [DSTAR_DIGITAL] D-Star simplex frequency Has any thought being givin to simplex ? � Here in Tampabay we have FM�nets on 147.550 and what I am seeing is some d-star users who don't seem to hear them tring to use that frequency at the same time. � If d-star has a simplex spot let me knowe and i'll pass it along.

Re: [DSTAR_DIGITAL] D-Star simplex frequency
Most of the D-STAR 70cm stuff also runs down to 430 Mhz., depending on local use and protecting weak signal, ATV, and satellite operations, it should be possible to find a range of 12.5 kHz. spaced frequencies in that part of the band for simplex D-STAR.
