[Repeater-Builder] Slightly
I have accomplished this in the past by using a simple summing resistor array as a mixer. This is then fed into a amplified speaker to compensate for the losses and provide a master control. Good Luck Bill N4XIR
[Repeater-Builder] MSF5000 CXB wont program
Hello all, I have a problem. I have 2 MSF5000's models X7CXB7106AT. I have tried programming them via; 1. A motorola rib box via the mike socket and the 40 pin socket. 2. A ribless cable via the mike socket. 3. I have used various computers, 386, 486 pentium 1 etc etc All to no avail. All i get is the message: SSCB no responding or Station not responding. I have tried normal codeplug read as well as the F5 station faild read, to no avail. These are great repeaters and my question to all would be is there any jumper or switch that needs to be in place to prg these ? I am totally stumped trying to get these programmed ?? Any help / suggestions would be greatly appreciated. Regards Steven.

I've done the same thing. In my instance, I used a communications speaker with my own amplifier tucked inside.

I use a Motorola amplified speaker and an audio combiner circuit. Since some of the newer radios don't like to have either of their speaker leads grounded I had to design a circuit that not only combined the audio but also isolated the speaker leads from ground. What I came up with was to use audio isolation transformers for each radio. A shielded audio cable goes from the speaker jack on the radio to each isolation transformer. Each transformer has an 8 ohm 1 watt resistor in parallel with the primary. This provides an 8 ohm load for each radio. These transformers are also available at Radio Shack. The secondary of each transformer has one lead grounded and the other lead goes to a resistor. Each transformers secondary lead with the resistor is tied together and feed the input of the Motorola amplified speaker. This is a simple resistive mixing network that isolates each radio not only from each other but from ground as well. Since this is a passive circuit there is some loss but the amplified Motorola speaker more than makes up for it. In actual use the volume level on each radio is just a little less than if you were using the internal speaker. And turning up the audio about 3/4 of the way produces enough audio to drive you out of the car. The disadvantage is as noted that all the audio comes from the same place and it is necessary from time to time to look at the radios to see which one is receiving. However if each radios volume is set at slightly different levels it is easy to determine which one is active. This has also been tried with the amplified Radio Shack speaker with almost the same results. It is pretty hard to beat the amplified Motorola speakers for loudness and clarity.

Re: [Repeater-Builder] Had at the hamfest
You've learned a lesson to do a little homework first. We've pretty much all had to go through the same experience at one point or another. You won't do it again. And you may have fallen victim to some seller who didn't know what he really had. Put it aside for the few useful parts it has and get another, correct, unit.

The seller indicated it was a 70 watt model, which would have been perfect. Once I got it home and opened it up, started looking at board part numbers and the Combination Number, it turns out I have one of the vehicular repeaters with a 300mw RF deck! ARGH! So, can I convert the RF deck to a higher wattage by adding the missing board in the PA (and where can I get one, and what would it cost?), or simply replacing the whole RF deck with one for UHF and higher power (same questions on this solution). Lastly, I could sell the radio to someone on here who might be able to build something out of it using other parts or parts radios they have around. Any assistance in this (and hopefully in the rest of a repeater conversion and parts seeking, like a control head perhaps) is gratefully accepted!

It works alot better when the speakers are mounted in different locations in the vehicle so you can tell which radio it's coming from without looking at it. Other guys I know that run multiple radios usually stick with really small speakers that they can stick right next to each other. Though I suppose you could spend a couple bucks and try some diodes? Another approach is to build or use an aircraft audio panel, which gives you two or three audio outputs. This is not entirely unlike the Motorola consoles that have select and un-select audio channels.

Re: [Repeater-Builder] Slightly OT: How are folks taking audio from multiple mobile radios and outputting them to one speaker?
Mike, If you decide to combine, make sure you look at the speaker circuit on each radio.The Spectra for example will smoke if you take it to ground. You would want to use a 1: 1: Transformer to isolate it unless you have a good combiner circuit.After asking the same questions you are asking, I decided on three speakers mounted on the side of the center console. Two years ago next month I was at Dayton and had a vendor who was selling speakers put audio into different size speakers. I then took the three SMALLEST I thought I could like with. Much better than the built in speakers. Goood Luck.JIM -- Jim Cicirello 181 Stevens Street Wellsville, N.Y. 14895 (585)593-4655

Turned out the xtal module connector was dirty. At the same time the RX died; that was due to a dirty connector on the IF/detector board, resulting in intermittent 10 V RX OSC voltage. Connectors are becoming quite the weak link in this radio series. Thank goodness for DeOxIt. Bob NO6B

[Repeater-Builder] crimping assistance please
I know this has been thrown around a bit before but I could use a little assistance. I just purchased a crimper and a couple sets of dies. I bought some cheap BNC and TNC connectors to practice with along with some RG-58A/U cable. I bought 3 different sets of dies. One of which is for RG-8 size connectors so I am not really concerned with that yet. The other two dies have hex crimp sizes of .324, .255, .215, .100, .068 and .215, .184, .068, .042 Obviously these two dies duplicate the .215 and .068 sizes. Basically I am not sure what size hex to use for the above stated RG-58A/U and BNC and TNC connectors. Also, I have a question regarding stripping the cable. I am not going to be doing high volumes of cables, but probably will be doing them on different size of coax. Would you recommend a stripper or will a razor knife suffice. Lastly, and relating to the coax strippers: Don't different connectors, even on the same type/size of coax, need different stripping lengths? This would probably translate into quite a few different strippers for different cables and connectors, no? Thanks Albert
