[Repeater-Builder] NHRC 4/M2 Remote Base Audio
Hello All, Today, I fed the remote base receive audio input of an NHRC 4/M2 with descriminator audio from a Motorola Maxtrac. I'm taking the audio right from the 16pin accy plug on the radio. When listening to the primary port of the controller, the remote base audio seems a bit high pitched and not rolled off enough. Has anyone else experienced this on this controller or perhaps I'm doing something wrong? Any help would be greatly appreciated. Thanks! Adam N2ACF Yahoo!

Re: [Repeater-Builder] NHRC 4/M2 Remote Base Audio
Hi, The remote base receiver audio input on the NHRC-4/M2 is set up for de-emphasized audio as shipped. If you want to use discriminator audio and de-emphasize on the controller, you need to change R19 to 510 K, change R20 to 51K, and install a .0068 uf cap in location C10. See page 2 of the schematic.
