[Repeater-Builder] OT: IFR MM-100E

Does any one have the manual for an IFR MM-100E. It is the accessory option found in the lid of either an FM/AM 1000 or FM/AM 1100S communications monitor. It is a cheap and dirty SINAD/Voltmeter. All I need actually is the value of R50. Thanks Bernie Parker K5BP

[Repeater-Builder] Re: PL (CTCSS) Filter

Hi Doug, Many years ago I had a similar situation. Instead of using the N06B filter I used the built in hi-pass filter in a Comm Spec PL encoder/decoder board. It is very similar to the NO6B filter. What was happening was that the filter was introducing twist (subtle distortion) to the DTMF

[Repeater-Builder] Complex Skywarn Paging System

I am just curious if any other amateur 2 meter repeater has a more complex RACES Skywarn paging system than the 146.88 W5FC Dallas TX repeater? The normal daytime amateur state of the repeater is 110.9 Hz full PL. To go into RACES Skywarn mode the following sequence occurs: 1. Repeater Mode
