[Repeater-Builder] Micor receiver voting tone
Does a Micor base receiver, unified chassis, have any capability for generating a voting tone? The Control and Applications manual does not make any mention of any cards that would do this.

[Repeater-Builder] Re: Micor receiver voting tone
If you need a Spectra Tac type operation, there are modules (for the card-cage/backplane), which serve up the proper tone encoding functions. Most often you will see a special version of the line driver module and a spectra tac encoder module. Motorola also had an earlier A-B tone voting system (that seemed to work pretty well). Finding cards for that system would be hit and miss at best. Depends on the voter you have, but the spectra tac module manaul should have descriptions of the more common back plane modules. The common module manuals can often skip over the spectra tac options as they are/were special order or as-built. I can't see why any duplex chassis couldn't be made to generate a proper encoder tone sequence, else you just need to properly add the circuit. Cetec Vega had a popular external voter tone encoder module, often seen installed after-market. cheers, skipp bd6xray [EMAIL PROTECTED] wrote: Does a Micor base receiver, unified chassis, have any capability for generating a voting tone?

[Repeater-Builder] Micor receiver voting tone
There was both a factory option and a field modification kit that allowed conventional Motorola Micor stations to be used in SpectraTac systems. First, a SpectraTac encoder card was added in the repeater card cage to generate the status tone that allowed the "in-cabinet" (repeater) receiver to vote along with the remote receivers. The encoder card normally produces a steady tone that is interrupted when a signal is received. The encoder module has low and high tone slide switches which are used in equalizing the tone levels (which are adjustable on the encoder card). Secondly, the status tone is routed out through a special four wire line driver so that the repeater receiver status tone and any received audio is routed on one pair to a SpectraTac comparator. The second pair of audio lines on the line driver is used to bring the "voted" audio from the comparator back to the repeater for retransmission. There is also provision for "in-cabinet" repeat, which means that if the comparator dies the repeater will repeat whatever audio the repeater receiver is receiving just as if there was no SpectraTac system connected to it. The special "SpectraTac Line Driver" also had circuits to add gain at certain audio frequencies so that the repeater's receiver audio response more closely matched the response curve of the remote receivers.

Re: [Repeater-Builder] 12 dB sinad value...
Skipp, In the Repeater Builder shop, we commonly use the HP 8920A service monitor for measuring bench sensitivity. It has the digital meter as you speak unfavorably of. We have found that the averaging of this function is adjustable. Making the averaging value 12 makes the thing work like my original Sinadder needle type meter, and takes a function that is basically worthless to pleasant. Of course, adjustments must be made slower, but I never hurry an alignment anyway. Kevin Custer skipp025 wrote: Thank you Kevin..! And I thought I was the only one who thought 12 dB Sinad was noisy.

The radio doesn't care, but if you're going to switch the fans with PTT or thermally, it'll be easier with 12 V. Also don't have to worry about cooling if running on emergency battery power.

I've had 2 of the 8920 service monitors for 10 plus years and still haven't gone through all the darned functions and scale options. :-) Great service monitors, I've got an inside track to the now retired HP Team leader for the 8920a/b project if anyone needs special information about the 8920a/b equipment. The 8920's are no longer in production... :-( I'm not in a hurry to align anything... it takes me 10 minutes to kick the over-weight office cat off my lap when I try to get work started.

At 01:23 PM 3/18/05, you wrote: Which fan would be better on the GE MastrII, and Motorola Micor mobile radio converted into a repeater; 12vdc or 120vac? Thanks in advance. Is your system going to go away if the 120v goes away? If yes, then 120v AC fans are usable. If you are going to use the battery backup facility in the Micor, then you will need cooling while on batteries and that means 12v DC fans. If you need fans at all - many Micor stations are convection cooled, and only need the fans if you run them continuous duty (i.e. lock to talk mode). Some folks will tell you that the 12v fans can put noise on the DC supply and thereby on the TX audio. This is true, but only if the TX audio circuits aren't filtered properly, and if the fans aren't filtered properly. You will need to put a filter on the fans, and the average fan takes much less than a quarter amp usually less wattage then the equivalent AC fan. Building up a filter for a few fans is trivial - a couple hundred UFs and an old transformer winding used as a choke. Run the DC to the choke, then the caps to ground. Put the fans in parallel with the cap. All of the audio circuits should be fed by their own filtered DC power... should be immune to noise on the DC supply line. If the fans are audible in the TX audio you need to properly filter the TX audio circuits first, then add filtering to the fans as well so that if one filter breaks the system is still clean. There is no excuse for half-engineered systems.
