If you can't find a dealer send me a private email and I'll point you at a good one. If you are going to need any ongoing support you really need to develop a relationship with a dealer, and you can start with buying a manual, which you need anyway. Note that while the repeater is synthesized in the exciter and local oscillator, the other stages still need to be tuned for your frequency. Mike WA6ILQ Yahoo!

Re: [Repeater-Builder] Re: M2 CAS
For those of you that are just beginning to experiment with repeater building, try using a little common sense. The manufactures would not have invested a lot of money in shielding and bypass caps if they thought they could get by with less. The MII "M" series mobile was never intended to be used as a repeater. Just because it works on some frequencies does not mean it will work on all frequencies. There is only plastic between the Tx and Rx and many common leads between the Tx and Rx. The MII "E" series was designed to function as a low power repeater with the Tx in the lower portion and the Rx in the upper portion. This provides some additional isolation between Tx and Rx. It does not eliminate the problem birdies that occur with all types of sets nor the leaky RF paths between the Tx and Rx. Possible elimination procedures are High Side Rx injection, swap out the IFAS and Hi IF boards for ones with a different IF, use more by pass caps, etc. Examine the MII repeater chassis; all leads into the RF portion of the Tx and Rx are bypassed with the older MASTR Pro connectors; there is plenty of shielding between the RF sections. If you want a good working repeater, take the time and invest some money in the proper equipment.

Hello Fred, Very good points. Question, have you successfully used an IFAS with a different IF frequency without modifications?

[Repeater-Builder] Remote Receivers and Optimal Use of CTCSS
Another in my periodic series of questions dealing with "best practices" (dontcha love bidness buzzwords?!) regarding remote receivers: In a system using remote receivers RF-linked back to a voter at the main site, should each satellite (remote receiver, that is, not "orbiting body") strip out and regenerate PL, or is it sufficient to simply let PL pass through and let all decoding occur at the main site? Assume "flat" audio throughout. Tnx es 73 de Bob K5IQ Yahoo!

Besides the obvious advantage of having only one decoder (less hardware), the fact that you only have one decoder means access time is quicker. The more decoders that have to open to bring up the repeater, the longer it will take to bring it up. It's probably also easier to match up the audio response and levels between the receivers, especially if you have an on-site rx that is hardwired. -- Jim Barbour WD8CHL Yahoo!

Re: [Repeater-Builder] Re: M2 CAS
The 30 to 50 MHz can be changed with out mods, however the VHF and UHF sets require extensive mods to the IF/Filter board. The IFAS boards are not different except for the Xtal filters.

[Repeater-Builder] Re: Comm Spec TP-38
Does the tone panel even display frequencies above 100Hz, just not decode them? That's a software problem or programing. Most other problems are hardware related.

The TP-38 only displays what tones are programmed to be enabled for decoding. There is a keypad command to step through and display all active tones that are enabled.

[Repeater-Builder] Re: tpl amps, not so broad-band
I took a look at the web page below and noticed the "may be tuned for broad band" statement. Most all the typical TPL Amps I have measure are semi narrow banded (which is normal and expected). Power drops off quite fast for frequency changes more than +- 5Mhz from the initial tuned frequency. TPL Amps set up for classic 450-470MHz operation are sometimes not easily retuned or best operated at lower 440-450 amatuer service. I've noticed this varies by amp model and the as-built unit. Bypass any tr relays if you plan to use it for Repeater Operation. Don't rely on the relay and don't rf switch the coax line if you can help it or you actually know about rf-hot switching and how to prevent it with delayed rf. You'd also be surprised how much power is lost in the tr relay circuit function /section of an amplifier. cheers, skipp www.radiowrench.com/sonic > From: "Joe" <[EMAIL PROTECTED]> > I did a Google on PA6-1BE and found: > http://www.wiscointl.com/tpl/Mobile%20Amplifiers.htm > > PA6-1BE Drive 8-15W Output 70-100W > Yahoo!

I have a new in the box, as in never installed or programmed, Kenwood TK-840 K3 version. Covers 403-430 mhz LTR or conventional. Has everything with it, bracket, mic, power cord, etc. Selling for a friend in the 2-way biz that bought it by mistake, as he needed the 450-470 model. He thought I could find it a new home amongst my "repeater buddies". You can have this one delivered to your door (in the US) for $180.

Re: [Repeater-Builder] Re: Comm Spec TP-38
Hello Skipp, I have all known tones turned on and active..(double checked that a few times) It will not decode them or show them at all it will show and decode all below 100.0 with no problem, and it does that like it should with no delay.. but if i try the 100.0 it has to have that tone signal present for at least 3 seconds before it will show or decode it.. it is like a audio amp gone bad or some thing.. but i did swap them around and reset the x2122 in the unit and still no difference.. I must be missing some type of failure somewhere..
