Re: [Repeater-Builder] UHF band opening
I know, but in many areas there are a lot of unused frequencies. Still, I would never seriously tell someone to operate there. I would also not recommend operating repeaters in the parts of the band where repeaters are prohibited. Others don't see this prohibition as a deterrent, however. The reason? The repeater bands are full and there is a desire to put more repeaters on the air. This goes back to a comment I made before. IF you can justify putting repeaters in all parts of the band based solely on lack of 'repeater spectrum', what is to keep you from being able to justify extending beyond the ham bands? Illegal is illegal no matter how illegal it is. We all know there is lots of underutilized spectrum just above and below 2M and 220. Is that a reason to put ham repeaters there?

RE: [Repeater-Builder] UHF band opening
Hi Bob Yes the shutdowns are ongoing. They will allow some fixed stations to continue but only at very low power. For all practical purposes the Air Force is imposing a quiet zone for 420-450 Mhz within 125 miles of the MA PAVE PAWS site and 150 miles of the CA one. Yes they did shut down 20 odd PAVEPAWS sites but the ones in AK, CA and MA were upgraded with all new equipment from Raytheon (?) and now do the work of all of the old sites, and also are better at detecting sea launched missles. These remaining super PAVEPAWS sites if you will, will continue on now for many years to come. The 440 guys in MA are all talking about moving to 900 or 220 or 2 m and there has been some talk about trying to get a primary allocation on the 700 band. But 440 is all through around here in MA as it is generally seen. That would be nice since we are secondary on 900 also. 73 Glenn -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Bob Dengler Sent: Wednesday, September 19, 2007 5:56 PM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] UHF band opening At 9/19/2007 01:52 PM, you wrote: But, what would you realign it to?

Re: [Repeater-Builder] UHF band opening
Does anyone know why the New England bandplan has inverted 70 cm pairs every 25 kHz (unlike the rest of the country, which is either all + or all - 5 MHz)? 25 kHz isn't close enough for any adjacent channel issues to be a concern. Bob NO6B

I believe it was done to accomodate radios that would not TX well below 445 MHz. Those repeaters could use LIHO and TX well between 447 and 450 MHz.

RE: [Repeater-Builder] UHF band opening
From what I've been told, when 70cm first started to take off for FM repeaters, repeater owners in the New York City metro found that they had fewer issues with desense and overload if they flipped to a negative offset (i.e. get the ham repeater Rx further away from the 450-455 commercial repeater Tx's). By the time the coordination councils got on the ball, there was a mish-mash of repeaters operating with either positive or negative shift. As a fix (using that term loosely), they decided that all of the odd pairs (44x.x25 and 44x.x75) would be negative shift and all of the even (44x.x00 and 44x.x50) pairs would be positive shift. This became the policy for the adjacent coordinators, and, like a bad cold, it spread up and down the Atlantic coast from New England to Virginia as more 440 repeaters came online. It's an ugly mess, and one that Ive made noise about fixing by having everyone go to positive offset to align with our respective neighbors to the west and south. Most of the coordination councils have been in agreement, but others remain opposed, so nothing has changed yet... --- Jeff -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Bob Dengler Sent: Wednesday, September 19, 2007 1:19 PM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] UHF band opening Does anyone know why the New England bandplan has inverted 70 cm pairs every 25 kHz (unlike the rest of the country, which is either all + or all - 5 MHz)? 25 kHz isn't close enough for any adjacent channel issues to be a concern.

RE: [Repeater-Builder] UHF band opening
I guess the thing to do would be change your tone to a different one that hopefully is not used anywhere else. Of course that still would not help with the strong skip signal capturing the receiver over weaker local mobile and portable users. Your right also in that the upside down pair should be abolished and brought into conformation with the standard band plan.
