RE: [Repeater-Builder] Anyone get RSS for MT1000 to run on a Dell M70 in DOS?
I use a bootable thumb drive with DOS 6.22 on a dual 1.8gHz laptop without any problems. Version R03.01.02 Moslo not needed. Have also used the same thumb drive on a Compaq P4 2gHz desktop without any problems. Might be just lucky but.

Re: [Repeater-Builder] opinions for a public safety repeater
We use Kenwood TKR for 2m and 70cm repeaters (2 ea), both drive TPL amps, 250 watt on 2m and 100 on 70cm. Been up for years, not one hick-up. You don't get the great rich audio from the old Kendicoms but good quality communications audio. ARCOM, Inc does commercial work as well as amateur.

While the subject is odd Helper stuff, remember the Mod Box or the Sineman? I'm a late comer to picking up extra Helper Instrument Equipment but I now have a modest collection of a few items like the Sineadder and a few of the antenna match boxes. I hadn't thought about it for a while but I even have a Mod Box somewhere. It's not nearly as useful as some of their other products still are, but it's at least neat to try and read the manual. I have a Helper Instruments Catalog (one of their last) in my collection (somewhere).

Thanks, Jed Hi Jed, The Kenwood TKR-750 and TKR-740 are both great Repeaters. The TKR-750 also has an amazing receiver. Proper setup of the receiver should normally include the front end pre-selector alignment using a special coax cable jig assembly and a tracking generator properly configured and installed onto the PC-Board matching input and RF sample port/jack. Most people and Dealers tend to do the more casual peak for max signal method, which results in very usable but not the absolute best sensitivity and performance. I'm very much amazed how many repeaters we service with rather odd looking (on the test equipment) tweak and peak front end alignment(s). So be sure to ask any Dealer what and how they prepare your equipment before they send it to you. The TKR-750 is more of a self contained ready to use repeater with a lot of built in features. Very popular for operations toward the 50 watt power level. The TKR-740 is more of system repeater meaning... how many owners often use them with external Power Amplifiers and Controllers. The TKR-740 has much less power output and normal operation assumed by most people is to include an external RF Power Amplifier. If you need to bark higher than a 50 watt signal onto the air the most popular method is to include (and use) an external RF Amplifier. You can save quite a bit of serious money by using the same external amplifier configuration with a TKR-750 Repeater and a higher drive (input) level External Amplifier. There's nothing in stone about driving an external high power RF Amplifier at the 25 to 50 watt level compared to spending a lot more money on a low drive level amplifier. TPL, Cresend and TE can and will sell you higher drive amplifiers for much less money and you end up with pretty much the same end product. In the hopefully rare case where an external amplifier might fail, continued repeater operation at the 25-50 watt power level is quite usable versus the very low power output of the 740 repeater. There can be different advantages to using the TKR-750 or the TKR-740 Repeater. cheers, skipp skipp025 at yahoo.com www.radiowrench.com
Re: [Repeater-Builder] RG21AU CABLE
The high resistance wire is nichrome. As I recall its attenuation is around 20 dB/100ft at 2m. I built an attenuator using it about 35 years ago. It handled the maximum power rating of the coax as long as the first 10 ft from the input was well spread out to prevent build up of heat. There is a more modern version of this cable with the designation of RG-221 or RG-222 (sorry I cannot find my Times cable handbook to verify the number). It's attenuation is approximately the same. Burt VE2BMQ Doug wrote: At 09:26 PM 24/03/2010, you wrote: Doug, From what I have found, RG-21A/U cable is 53 ohm impedance, 0.339 outer diameter, double silver-plated copper braid shields, and a solid center conductor of high resistance wire. The dielectric is solid polyethylene, and the jacket is black PVC. If you have a sample of this wire, please reveal what is printed lengthwise on the jacket. 73, Eric Lemmon WB6FLY Hi Eric. Well it has Plastoid Corportation RG-21/AU on the black jacket. It is stiff coax. You describe it very well. I sort of remember using something like this to reduce the power of an old Prog line unit... Here in Canada they didn't allow us to turn the power down, you had to use an attenuator.

I kind of remember him playing around with an attenuator pad to go ahead of a service monitor. I don't remember the wattmeter part though. There was a guy in California making a 40 db power pad to use ahead of a service monitor. It was made during the Singer monitor era to go in front of it. It had a port for the transceiver and one for the signal generator and another for the receive input on the monitor. It worked pretty well. There may be a few floating around yet.

[Repeater-Builder] Re: Helper Instruments (Voltadder VA 502)
The Mod Box was a great idea during it's time. Only the IFR-1000 at the time had the provision to use a microphone with a pre-emhasis network. Most all the service monitors only allowed an internal tone or external audio gen. Some allowed the mix of both. The Mod box was sort of like a microphone and two source tone mixer. The Power pad was neat b/c unlike an isotee or throughline power attenuator, you could combine both ends of a service monitor, especially one with duplex/offset generation to a device at the same time. Leave it attached permanantly and take into account the attenuation and never worry about accidently frying it. We bought a couple of the Com-Ser (Neo-Lampkin) units. Still have one. These were single port devices based on a thick film hybrid in a big heatsink. They made some neat add-on stuff too. They had a banded, two way amplifier/preselector that raised the flea power output of some of the earlier monitors to +dbm levels, preslected the input and output for clean output and microvolt sensitivity of the monitor for OTA monitoring. Moot point with later monitors of the 80's. --- In Repeater-Builder@yahoogroups.com, Tony Faiola fai...@... wrote: On Mar 24, 2010, at 11:06 PM, Gary Schafer wrote: Yes he did build some for a few years.

I don't remember the wattmeter part though. There was a guy in California making a 40 db power pad to use ahead of a service monitor. It was made during the Singer monitor era to go in front of it. It had a port for the transceiver and one for the signal generator and another for the receive input on the monitor. It worked pretty well. There may be a few floating around yet.

[Repeater-Builder] Re: Squelch crash on a MSR2000
Just to add my two cents to the discussion. The Motorola Micor and squelch modification is not 100 %. The and squelch in the Micor starts to function after the receiver has about .8 uV of signal. Encouraging your users to put their best signal into the repeater will minimize this effect. The Micor book has the mods. Good luck. As has been pointed out, the audio delay line almost always works.
