RE: [Repeater-Builder] Can a Master 3 narroband
Yes, and the switch from 15 kHz (wideband) to 5 kHz (narrowband 20K0F3E) was simple compared to the "new" narrowband 11K2F3E emission, which has specific emission masks that are mandatory. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of Chuck Kelsey Sent: Friday, August 27, 2010 12:32 PM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Can a Master 3 narroband I'm guessing it was permitted back then.

RE: [Repeater-Builder] Can a Master 3 narroband
Tom, The "narrowbanding kit" produced by Communications Specialists and others is for the receiver section, and does not affect the transmitter section. The emission mask specified by the FCC for mandatory narrow band operation must be incorporated by the equipment manufacturer and then tested by an FCC-approved agency. This process has never been in the hands of the owner or user, despite widespread popular belief to the contrary. Simply reducing the deviation to a lower setting does not magically make a transmitter narrow band compliant; the limiting circuitry must be modified as well. Moreover, the FCC Type Acceptance for both the MSR2000 and the Mitrek does not include narrow band (11K2F3E) emissions. Naturally, these requirements apply only to commercial usage under Part 90 Rules. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of Tom Manning Sent: Friday, August 27, 2010 10:57 AM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Can a Master 3 narroband Hello Jim I note your message about narrowbanding and the comment about the MSR2000.

Re: [Repeater-Builder] Can a Master 3 narroband
While it is possible to use one of these narrowbanding kits, it would not be type accepted for commercial use unless someone paid for the testing and filed with the FCC.

Re: [Repeater-Builder] Can a Master 3 narroband
Hello Jim I note your message about narrowbanding and the comment about the MSR2000. I have seen no info on doing so but it seems to me that the MSR200 could be narrowbanded. The MSR is very similar to the Mitrek and it can be narrowbanded by using a kit by a company that slips my mind. Therefore I feel narrowbanding would be possible. I will be attempting this in six months or so. 73 de Tom Manning, AF4UG - Original Message - From: Jim in Waco WB5OXQ To: Repeater-Builder@yahoogroups.com Sent: Friday, August 27, 2010 10:07 AM Subject: [Repeater-Builder] Can a Master 3 narroband I have a uhf master 4 that has been used for years as a paging exciter.

If it has the correct IF module it can. Early modules were wide, Later modules were Wide/Narrow software selectable.
