What he said. When I got into ham radio, some fifteen years ago, PL was a "big" deal for the vocal minority who didn't want to spend money on a PL-capable radio. Recently, I took part in a service event and it marked what I believe to be the first time in thirty years that a service event has used local repeaters with CTCSS enabled on the repeater. We didn't lose any participants when it was enabled. > Besides, D-STAR policies have been in place in most areas for quite > some time, now, and they are very similar to SNFM. D-Star is just another repeater, and a new technology, needs to be afforded a chance to grow. Beyond that, it's still just another repeater. So sure, cancel a paper repeater to give it a proper pair, but once you've got one allocated, I wouldn't bother to make alterations to the order of coordination. -- Kris Kirby, KE4AHR But remember, with no superpowers comes no responsibility. --rly
Re: [Repeater-Builder] Are you ready for narrowbanding? | FCC requires systems transition from 25 KHz to 12.5 KHz channels
Even though it is not a requirement here in CT, I have a narrowband (12.5 Kc) FM repeater on the air (that has been narrow for almost 3 years now). What I have noticed is that ham rigs can do narrowband and DPL more and more (the first one I had that was capable of narrow band was purchased around the year 2000 or a little before). Most any ham rig out there now seems to be able to handle narrow operations. The only thing I have noticed is that with the exception of the Kenwood TM-271A, there does not appear to be a ham rig that can do 2.5 KHz channel steps without getting into the HF/VHF/UHF class radios like the FT-847 and TS-2000. Lastly, I am surprised at how many people access the narrowband repeater and do it correctly. In the beginning we did have several people trying to access it in wideband mode. The other nice thing about doing narrowband on the repeater is that with the 15 KHz channel spacing here in CT, I do not get any crap from adjacent channel repeater users that I have ever noticed ... just some crap from the tower in the wind :) If anyone is ever in the area and wants to play ... it is on 146.955 with a DPL of 343 (in and out), and is linked to 5 other repeaters in the system. Many have said that it has better audio than the wideband stuff that I have on the air, and I do not use "X-pand" or compandering. The repeater is located in Morris/Bethlehem CT and covers to the north/northeast (so that would be up towards Hartford and north) better than any other direction.

Yea - like the majority of hams are going to buy replacement rigs, or (trying not to burst a seam) modify their rigs for SNFM! These are the folks who can't even install a CTCSS encoder if their life depending on it! Yea - narrowbanding is going to be a real big deal in the ham bands. Besides, D-STAR policies have been in place in most areas for quite some time, now, and they are very similar to SNFM. I know WPA has rules for narrowband systems in place. Joe M.

Obviously this requirement does not apply to Amateur Radio, but amateur repeater coordinators for densely populated areas, i.e. Southern California, NY-NJ and other areas would do well to start thinking about this looming situation. Have you tried to get a 2 meter or 440 MHz repeater coordinated lately? http://urgentcomm.com/policy_and_law/commentary/narrowbanding-migration-1209/ P.S. There are some good links at the bottom of this article. Ken WA6OSB
