[Repeater-Builder] Pyramid VRS to Motorola X9000
I am looking for imformation to make a cable to connect a Pyramid VRS to a Motorola Lowband X9000. The print out provided by Pyramid works but its keeps the Pyramid in constant transmit. Thanks for any help in advance Mike
[Repeater-Builder] Racom Station Identifier
Hi all I have a Racom 1300 morse code station Identifier. I am looking to see if there is a way to reprogram the Prom in the unit. The company is no longer active. The prom contains the call sign information. I know I could throw it in the trash and buy something new but I hate doing that when all it would take is to reprogram the Prom. Is there a way to read the prom and then change the information in it and then program a new prom provided I can find a new one. Thanks in advance Mike
[Repeater-Builder] Re: Micor repeater audio
Kevin Thanks for the repleis. In referance to the channel element, is there a way to sweep the element by it self, or is that something that ICM or someone like that would have to do? You've hit on something I hadn't thought about. If this could be done by it's self it would be better than having other items in the circuit that would contribute to the problem. Also in support of this idea of the channel causing the problem I've switched exciters but not the channel element. I wouldn't be apposed to having ICM crystal up a new channel element but I want to make it's the problem first and then I'd want to make sure the new element wouldn't have the same problem.

The audio levels and on frequency adjustments have made and to seem to be on the money. This is an unmodified repeater station using stock cards and no controller. The receiver is stock and the frequency has been changed to the 440mhz band. The audio coming out of the receiver has fine audio quality. Just looking for your thoughts or ideas. Thanks for your input Mike I'd make sure the channel element is not limiting the quality of your audio. Consider doing a sweep of the frequency response at several deviation levels and see what you have. I've seen re-crystaled elements that were less than good. Kevin

I am interested in converting this antenna to function as a 450-470 MHz antenna (model DB404B). Has anyone done a conversion like this before? Common sense tells me that I could be able to modify the size of the dipole loops. Would like to hear your experiences or suggestions. Jay, KD4BPZ Yahoo!
