Hey folks, been a while! Anyhoo, last night I had a unit with a regular (non-Astro) AAR Spectra, and it had an odd pattern, 12 small holes with a bunch of smaller holes in between, stamped into the grill down near the 7 and * keys. It looked factory from what I could tell, and had no differences ...

Hey folks. How often does the connector on the HT1000 have issues? A coworker has one that, as of late, he can't use a speaker mic on. We've tried three different mics, none work. The internal mic works fine, so I'm thinking it's something in the connector or inside the radio. Novice question, my ...

Central Oregon & Pacific Railroad here. As for an adapter that you can put a mobile in, then slide it into the AAR Spectra box, no. I can't help with that. Just on a side note, we went to Kenwoody mobiles with external speakers. This sucks because the damn mics stick, cords are already fraying ...

GP-38

Well, here a little over a year later...I took the MT1000 in to be reprogrammed on Monday. I got it back yesterday and lo and behold, it beeeeeps on powerup like new! One of the unsolved mysteries of Motorola, I guess.

I have an NMN6128C that recently took a crap. The cord on this particular one started as a coil right out of the strain relief on the mic head, whereas others I've seen have a short length of straight cord before the coil starts. These two variations seem to share the NMN6128C designation. Any ...

Our crew van has a Kenwood mobile in it, not sure which model or how many watts, but transmitting in the parking lot on any channel (railroad band) makes the customer detector at 7-Eleven go ding, ding, ding with each click of the mic. They've said Winston PD likes to do that, too.

You know those ...

Tom, interesting information. Thanks!

dxon2m, yes. I'm talking about the Central Park Zoo in Manhattan. So one could expect to see a mix of GP300 and HT750/1000? Any specifics on which craft of employee use which?

GP-38

This shouldn't be too far OT. I'm trying to find out what the various staff at Central Park Zoo use in terms of equipment and band(s). I saw a picture of one of the security guards wearing what looked like the old MT500-type speaker microphone, but it's got to be something newer. Any information ...

To KD6KML: Those switches sound neat. Which road are you referring to? But yeah, I know DTMF has many cool functions in railroading. We have some crossings that can be called to activate from the DTMF pad. Down at our interchange with the UP in Black Butte, CA we have yard lighting that is turned on ...

GP-38

Oh I suppose it could be possible that you could put another whole radio in the left side, but in this case it was just a remote head. (Notice in the bottom picture the plugs for external microphone and remote cable.) On the right/engineer's side, there was a complete AAR Spectra. On the left ...

My appologies for the long wait. Welcome aboard UP AC44 #6156, formerly Southern Pacific #108. The overhead panel seems to harbor two Spectras, correct?

Whoa! First off, I didn't mean to start a brand new thread regarding this matter. Obviously hit new topic instead of post reply. Anyway, mods please delete if necessary.

My understanding is that the earlier HT1250's (and thus, those with firmware/software issues) had (M) MOTOROLA printed on the ...

GP-38

...and it's definitely a 128-channel radio. Box sez: AAH25KDH9AA6AN HT1250 136-174 1-5W 128 CH FLK. The software version is R05.04.00, and the (M) MOTOROLA emblem on the front is a recessed decal, not printed ink as I was told to avoid.

I took the radio out of the box an hour ago and I'm still ...

I hope I'm not veering too far off topic, but since I started it and we are sharing cab photos...this was taken on the same day as the Astro Spectra shots. I have no idea who that freak is *cough* but anyone in the know will see from several indications that we weren't really moving. Crazy things ...

That thin strip of metal is actually one of the electrodes for the heated windshield. And boy, they work. That glass gets hot!

It always cracks me up to see DTMF microphones in a locomotive. And the keypad on the Spectra is what...three to six feet away? I mean, a mic on each side in crew cab units ...

Frick. The back panel had fallen off on the way down from Eugene, too! I only found out it was an Astro after I had replaced the panel. Now I wish I had looked back there again.

Ironically, we had one of the brand new UP SD70ACe locomotives (UP 8320) on the hauler this morning. The cab was pristine ...

GP-38

SD70MAC, it was the Norfolk Southern 6638. I think I saw a build date in the cab of 1986.

GP-38

Thought some of you might find this interesting. We had a Norfolk Southern SD-60 motor in our hauler consist over the weekend. Talk about mind-boggling...you walk into the front door expecting to see two conductor's seats, and you see a control stand in front of you! Across the cab, where the stand ...

Awsome picture! I dig that speaker, but also check out what's to the right of it. The base of an old Dazor Floating Fixture microphone boom! Our dispatch microphone at the railroad (Rat Shack 33-2003) is supported by one of these! Do you know if the mic on the end of that one is an old Elvis style ...

K2HZ, indeed it was a UP ATX. I both like and hate them. They are nice because, obviously, as long as there's air in the brake pipe they never die. The bad thing is, if you've got a long (75+ cars) cut with an ATX on one end, you can't just go ahead and arm him once the engine/s pull to clear. As ...

Out of the box, no. A JT1000 can not encode MDC1200. I'm not sure if you can throw an option board in there for that. Search this topic and you'll find more in-depth discussion.

GP-38

Not sure if this is voting, but it sounds like it...when we go north, we have to call UP dispatcher 68 in Omaha, NE by dialing *68 on the locomotive Spectra keypad on channel 1414. The DS will almost always come in crystal clear, but if not, we can ask him/her to try a different tower, and it will ...

Last week, one of my 99 ch. VHF MT1000's (H43GCJ7190CN) made an absolutely hellacious noise, like a scratchy squeal, when I turned it on. It hasn't beeped on powerup since! Everything else seems to work fine. No channels were lost, transmits and receives, display lights, monitor button drops the ...

I'm a conductor for the Central Oregon & Pacific Railroad, so I've got some info to share. Portables are mostly HT1000's for train crews. The ones up by Eugene and down by Black Butte, CA are HT1000 w/ DTMF for use on the UP microwave system. Managers have HT1250's and 1550's w/ DTMF. One conductor ...

Hey all. At work, one of the conductors HT1000's tends to transmit flatulent sounds along with his voice. I recently realized it's usually during colder nights, too. It's getting shopped, but I'm curious as to what could cause this.

GP-38

I don't know about your VHF HT1000's. It sounds like your UHF HT1K's are set up for either PL or DPL. When my VHF HT1000 is set for CSQ RX (position A on the ABC switch) and receives, there is no light. When it's set for PL RX (position B) and receives, the light flashes red. I'm not sure why the ...
