[Repeater-Builder] Motorola T1504A Duplexer Lock Nut
Hi, Does any one in the groups have on of these in their junk box that they don't need? I took my duplexer to get tuned only to realize that some genius thought that duct tape was a suitable replacement for a proper lock nut on one of the cans. he did the tuneup on the duplexer as best he could. after i locate a nut i would love it if their are any local hams with the capability to give it that final tweak as i am sure that one can is out of spec. thanks, robert kc8gpd

I should have noted that i have moved from the jersey location to the tuscaloosa, al area. also if there is a ham club as well who wants to host a gmrs repeater, it would be open to suitably licensed members of the club.

The problems didn't seem to make any difference regardless if the user was 2 miles out or 10 miles out. Then either you had lots of foliage absorption (lots of trees in Oregon), which affects 440 more than 2 meters, or you just got a bad antenna. The fact that you changed sites along with antennas may have changed the absorption issue. I have 4 GP9s in service then all work very well on 440. The one I have on the 5200' mountain significantly outperforms a DB-420, which is now my backup TX antenna. Bob NO6B

I am looking for the wiring harness for the S-800 series Control head. Not the large cable, but the smaller harness with the ignition sense wire, speaker etc. Thanks wx3m.te...@gmail.com

Ouch. Maybe a regular nylon lock nut would work acceptably well and be a little cheaper? Isn't the outer sleeve (the one that the lock nut threads onto) slotted? If so, will it tighten up enough to keep the shaft from beint turned if you just use a a regular nut? --- Jeff WN3A -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of n...@no6b.com Sent: Sunday, January 10, 2010 11:45 AM To: Repeater-Builder@yahoogroups.com Subject: RE: [Repeater-Builder] Motorola T1504A Duplexer Lock Nut At 1/10/2010 08:28, you wrote: Try here: http://www.mcmaster.com/#hex-locknuts/=5bcw46 http://www.mcmaster.com/#hex-locknuts/=5bcw46 Click on Flex-top Expanding Lock Nuts McMaster-Carr - of course!

If so, will it tighten up enough to keep the shaft from being turned if you just use a regular nut? The outer 1/2-20 threaded sleeve is slotted, but doesn't appear to be tapered. I don't have one handy to try it, but I think a plain 1/2-20 nut would just thread down the sleeve without compressing it, which creates the locking action. Hard to tell if a nylon lock nut would generate enough pressure to provide an adequate lock of the tuning rod; I think not. Sal's idea of using small hose clamps is starting to look good ;) Bob NO6B

[Repeater-Builder] Those PGE Smart Meters (again)
Re: Those PGE Smart Meters (again) I was on the phone to PGE (the California Based Energy Provider, aka our Utility Company) yesterday asking for a Service Address Electricity Turn-On. No problems getting things set up and when I asked about providing access to the site... I was told physical access for restoring Electric and Gas Service was no longer necessary with the Smart Meter Retrofit in place. Seems they can turn electric service on and off by remote control. And the Agent told me they can easily track energy consumption with time of day. Sure enough even the Natural Gas Meters now have Smart Meter boxes on them. I'll have to look/ask how the Gas Meters obtain electric energy. Probably a long life battery recording usage... only. Both good and bad depending on your opinion... The classic no free lunch rule applied when the Service Representative told me they still couldn't turn-on the electricity/account for a minimum 3-days because that function was done by another Dept he wasn't in direct communications with (one of the three days was a Sunday). Those meters are smart... and they have control to the On/Off Switch by remote control. cheers, s.
Re: [Repeater-Builder] Those PGE Smart Meters (again)
Just FYI, if you're not familiar, the utilities (PGE and SDGE come to mind) can remotely turn off complete circuits, and have had this ability through SCADA for years and years. They are just now getting to the point where they have the resources and capability to do this for each end user. -Brian On Sun, Jan 10, 2010 at 10:12 AM, skipp025 skipp...@yahoo.com wrote: Re: Those PGE Smart Meters (again) I was on the phone to PGE (the California Based Energy Provider, aka our Utility Company) yesterday asking for a Service Address Electricity Turn-On.

[Repeater-Builder] Mitrek repeater conversion cos problem
I'm converting a lowband Mitrek for 6m repeater use. Most of the mods have been done according to http://www.repeater-builder.com/mitrek/mitrek-interfacing.html The problem is that at the emitter of Q406 I can't get a valid signal when I feed the receiver with a 5kHz modulated signal. Only when I modulate it to 6 or more kHz I get about 3V/0.11V. For the squelch I put a 25k trimmer with one end to ground, with the other end via a 3k3 resistor to pin 11 of the control connector and the wiper is connected to pin 14 of the control connector. The radio is not equipped with a pl board, the controller I'm trying to interface will do this. In a later step I also need to narrowband the radio, therefore I'm a bit worried. Does anyone with more Mitrek experience than me know why this could be? 73 Martin

And the Agent told me they can easily track energy consumption with time of day. i have always had a problem with this. it eventually leads prices based on the time of day you use energy. as if they don't gouge you enough already they want more for usage during certain times of the day.

RE: [Repeater-Builder] Re: Those PGE Smart Meters (again)
Look on the bright side: The smart meters allow the electric utility company to immediately identify a power outage and identify the areas affected, which can drastically reduce the restoration time- especially in rural areas. With rural customers on conventional meters, some outages would last for many hours, even days, because some customers always think that someone else will call to report an outage! 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of kc8gpd Sent: Sunday, January 10, 2010 2:51 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Re: Those PGE Smart Meters (again) And the Agent told me they can easily track energy consumption with time of day. i have always had a problem with this. it eventually leads prices based on the time of day you use energy. as if they don't gouge you enough already they want more for usage during certain times of the day.

Who's the nicest person you know? No silly, not me it's the person who gives you a million dollars. But I have the answer to your question/problem. I'm a fully Authorized Kenwood and Pyramid Dealer and Service Station so I've seen this question a few times... The tk-780 tk-880 has two surface mount resistors that need to be relocated to allow external audio through the kct-19 cable (external input). And just to make life more enjoyable I'll now tell you the Service Manual does describe those resistors when using the KCT-19 but I know for a fact that most of the early Service Manuals have the configuration wrong/backwards. So once you get the two resistors moved over to the reverse of what the Service Manual indicates, you also need to enable the external path PTT in software. To enable PTT input on pin 8 of the KCT-19, under Edit/Optional Features, program Com2 as Aux Hook/PTT. Move the resistors, change the programming and the tk-780 radios should start transmitting audio through the external kct-19 input port. You will probably need to have a copy of the Service Manual to understand the mentioned resistor(s) locations and configuration. that is all... cheers, skipp skipp025 at yahoo.com www.radiowrench.com phillmobile phillmobile@ wrote: Hello all i am working on interfacing a tk-780 with a gm300, which will be mounted in my car for crossband repeat so the problem is as follows when the gm300 rx the tk-780 tx but there is no audio or depending on the setting the mic on th tk works for audio so you key on a ht to the gm300 and speak in to the mic on the tk and it transmits that audio unless you have it disabled then you get no audio but i know that i am getting audio from the gm300 to the kct-19 i have tested it i have tried for hours and have tried a tk-880 too same issue i have tried both pin nine and pin five on the kct-19 and many hours checking and testing different switch settings in the software it just won't work but the other way back to the gm300 (uhf) works perfectly, so looking for some pointers, my references are the pyramid svr200 to kct19 wiring plan and the tk-780 service manual and its european so its kpg-60d any thanks in advance
