Re: [Repeater-Builder] Re: Opening Salvo Poor Mans Repeater Project
I'm sorry. I should have been more clear on my first post. This repeater was being built for GMRS NOT FRS. The FRS radio I was using has a trim cap on the crystal for the PLL allowing it to be tuned to the GMRS frequencies. This radio is for receive only. The PTT button has been removed. It has also been modded to accept an external antenna. No transmit = no type acceptance issue. --- Jim B.

My only response on this topic since Kevin doesn't allow rules discussions. GMRS is allowed up to 50 watts TPO unless you are operating a small base station, then the 15 watt rule comes into play. A small base station operates at 5ppm minimum frequency tolerance and a standard base station or repeater must maintain minimum of 2.5ppm. A small base station also has height restrictions. Also, 50 watts TPO is allowed for mobiles and frequency tolerance is 5ppm or less. If you are within the line A or line C paramaters, certain frequencies are dis-allowed, power is not the issue. Gain antennas are also allowed and there are no restriction on that. Bob, GMRS WPVV845, Amateur KG4WAD, LMRS WPXC892 --- In [EMAIL PROTECTED], Paul M Schmitter [EMAIL PROTECTED] wrote: Ooops.

Thank you for all the info. Part 95 is not written very clearly. There seem to be many interpretations. --- rtoplus [EMAIL PROTECTED] wrote: My only response on this topic since Kevin doesn't allow rules discussions.

Re: [Repeater-Builder] Re: Opening Salvo Poor Mans Repeater Project
Actually this is aGMRS repeater. The trim cap on the crystal for the PLL had enough adjustment to get it on to the GMRS freqs and since I'm only using it as a receiver, I don't have to worry about type cceptance. GMRS is not required to ID, so I chose 15 minutes for testing. --- Dennis Zabawa [EMAIL PROTECTED] wrote: --- In [EMAIL PROTECTED], Paul M Schmitter [EMAIL PROTECTED] wrote: I'm actually working on improving my poor man's repeater right now. .. Using an old Radio Shack digital voice module(20 second), I recorded an ID message. Using a 555 timer, I created a pulse to trigger the ID every 15 minutes. I am assuming the this is an Amateur Radio repeater for 70CM. If so, the ID interval is required to be no more than 10 minutes. Dennis KG4RUL __ Do You Yahoo!? Tired of spam? Yahoo!

[Repeater-Builder] Re: Opening Salvo Poor Mans Repeater Project
I have a number of radios hard-coded for use in/on the dot and frs frequencies. But I also have a copy of the special hard code software to make the same radio change frequency. They are not all like that... from at least two major radio brands, which I have first hand experience with. The mfgr is just not the business of telling you the frequecies can be changed with very special software not normally not available outside the factory or in the USA. cheers, skipp How do you know that that radio won't drop into the ham band? Because it's an FRS radio-channels are hard-coded into the controller. They are ALL like that.
