Re: [Repeater-Builder] Motorola Radius P50
I will certainly check those out. Thanks for the Item #'s; It saves me from searching around. Those prices sound very fair. Ooops almost forgot, Thanks for sending me the $2 bucks you owe me for cutting and sending you that Uniden key. I will put it towards a radio. There's that darn CRS again! :-) --- On Sat, 4/10/10, Mike Morris WA6ILQ wa6...@gmail.com wrote: From: Mike Morris WA6ILQ wa6...@gmail.com Subject: Re: [Repeater-Builder] Motorola Radius P50 To: Repeater-Builder@yahoogroups.com Date: Saturday, April 10, 2010, 5:54 AM At 10:46 AM 04/09/10, you wrote: Sorry, bursting your bubble was truly not my intent.

I soldered a jumper between the collector of Q6 (PL INDICATOR output switch) and PIN 14 (XMIT PL INHIBIT).

[Repeater-Builder] Slightly OT: How are folks taking audio from multiple mobile radios and outputting them to one speaker?
Hello Folks, I am wondering what people are doing these days with multiple two-way radios and scanners in their vehicle and then outputting it to one speaker in the vehicle? How are they isolating each radio? Thanks, Mike
Re: [Repeater-Builder] Slightly OT: How are folks taking audio from multiple mobile radios and outputting them to one speaker?
Personally I'd rather have each radio going out its own speaker. 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?

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.

[Repeater-Builder] Had at the hamfest
Bought a Mastr Executive II unit today with the idea of making it into a UHF repeater. 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!

RE: [Repeater-Builder] Had at the hamfest
I feel your pain! Sorry, but the Mastr Exec II Vehicular Repeater is not good for anything other than a few spare parts. The receiver is about the only part that is useful in another chassis. It would be easier and cheaper to simply buy the rig you want, rather than try to modify your VR. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of AdamW Sent: Saturday, April 10, 2010 1:38 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Had at the hamfest Bought a Mastr Executive II unit today with the idea of making it into a UHF repeater.
