I just modified my HT1550s for FPP with any battery by cutting open 2 dead red batteries and removing the chip, then installing it inside the radios. There's more room in the VHF than the UHF, and you have to remove the chip RF choke to isolate it from the center terminal so battery status still wor...

Will it work? Physically they are the same as the RMN5127, but will the programmable mic functions work?

Motorola's biggest policy screw up to date. This is worse than the 30 year long problem I went through with them over the PTT disc contacts that wouldn't give any sort of tactile feedback.

Apparently Motorola wants to obsolete this radio by discontinuing a little dinky part, the 35-86092Z04 felt speaker cover! Does anyone know of a source for a sheet of similar speaker covering that could be cut to size? I know I can still get the HT (Waris) series speaker covers, but who knows how lo...

A search came up with this.

That's what I'm after. Thanks.

Either of these interest you?

Saw those, but trying to stay away from RG-174 and other small coax.

Wrong direction. I need the QMA antenna cable to mini UHF adapter. Can't find it anywhere. Makes wattmetering installations impossible.

I can find MPL female-QMA male adapters for connecting to the radio end, but no MPL male - QMA female adapters for connecting to the coax end for wattmetering an installation.

Anyone have a source for these?

I remember some of the Nextels were:
Toucan
Falcon
Marathon
Raven

Also, CM200 is a Marlin
Minitor V is a Terrapin
MT1500 was a Mako
PR400 was a Piranha
CP100 was a Rio
XPR4350 was a Morpheus
Some recent APX mobile is an Odyssey?

Is there any way to modify the line input/output board for hi-Z on the receive line output? I can't find a schematic for the board, and it doesn't have the options of the international CLN1204 board.

Never mind, I found it. 8000, 16 bit, mono, PCM.

What format do I use for this? I've found the existing ones use .wav 8kb mono, but can't find anything after that (PCM, CCITT, etc.)

So, what is the latest and best mod for 222-225 with 5k deviation, 20k steps, and squelch? HT1250LS+ Tanapa PMUD1761B here.

I have both my UHF and VHF HT1550 radios set up with the first zones as public safety only for the two closest counties. Third zone is local ham frequencies, other zones are "travel zones" with mixed ham and PS freqs for north, west, and south, and the rest are our shop's customer freqs. T...

You wouldn't believe the counterfeit Waris housings I've seen. Thin gold plating on the flex contacts, press-fit (not molded-in) microphone screw-in parts, speakers shorting to the frame, factory reject LCDs, and so on.

I thought there were two versions, the Motrar 5 and the Motrar 20. I do remember that if you wanted anything higher than 5 on a portable, you had to go to the STX. And I just got a MTX8250 back from depot with the code name "Satria" referring to the front cover. Haven't seen that one before.

Is there a list anywhere with all of these names? I searched and can't find one.

* A more reliable RF section * A charging/battery system that doesn't pit the charger contacts * Pager side charging contacts that are easier to clean * Programmable voice prompts and alerts (i.e. PAGING FIRE ONE, PAGING FIRE TWO") * Longer voice storage, like an Icom F50V * PARTS THAT WE CAN A...

I once did a similar comparison on the MX mount antennas, and found that the short VHF HT750 antennas were a good dummy load (outperformed by a standard stubby 3" VHF by 3db!) and the new NAD6579 "gain" long ducky indeed has as much gain as one of those half-helical half-whip armpit p...

I have a ribless CDM1250 cable with a homemade inline CM200 adapter, a 12volt car alarm remote battery stuck in a DB25 flashing adapter to power it, and a RJ45 to 25 pin adapter. Works for most things with simple 2-wire programming. I also have a USB programming adapter with a male 3-conductor 3/32&...

I've done two now, and it seems that the better way is to cut the label side panel just inside the edge on the panel's sides and bottom, then pry the batteries and plastic up and out. The cells were replaced with Eneloops or Duracell "pre-charged" rechargeables, which are above 2000 mAH an...

Anyone remember the Motrar? It was a Maxar 80 with a trunked logic board/synthesizer added - a real ugly Frankenradio. We used to call it the Mo-Toad. If you've never seen one, imagine a Maxar 80 with a huge beer belly.

Don't forget to include the APCOR with the MX300 series.

At our shop we use a 15 ohm pot across the speaker leads (1 and 15/16) and the speaker goes from 1 to the wiper of the pot. Side note: some speaker/pot combinations have enough room where you can drill a hole centered in front of the speaker and mount the pot there. The Micor/HSN9236 square plastic ...

The scotch taped ones never moved. The original Motorola taped ones would move all over the place. Now that's scary.

At work: Nextel i860 modified with Pageboy III metal clip on back, V or U HT1550XLS depending on which customer I'm visiting. At home: The Nextel and an EX560 VHF by the bed for when the dispatch centers call with their reports of hearing "strange noises" on the systems. You know, the nois...

Up until they discontinued it a few months ago, I'd use a 3905834K04 contact instead of the original one for a better "pop". I once suggested this to a Motorola engineer, and was told "we can't do it due to migration issues." The new part number is 3905834K06 with a little less p...

I usually program everything on VHF to receive a weather channel or UHF to receive 464.500.

And no, I don't give it an alphanumeric name of "FAIL 01/90"...

I've seen complaints about (and have experienced!) some poor quality HT1550 receive audio, and did a little experimenting. I found that the audio quality improves slightly when using a P1225 metal baffle (the one shaped like a Tele-Path ad asterisk) in front of the speaker. The audio also sounds mor...

Somewhere I have a picture of a red Minitor 3 that was left out in the sun and turned PINK!

Is there anyone out there who knows whose voice is on the "Selective call frequency ONE!" announcements? I know it isn't the late Don LaFontaine...

I'm also looking for the same thing for a county-wide system.

Never mind...had to hack my old conventional Saber cable to make it work with the Astro. Now the Win RSS works OK.

Model H04KDC9PW5AN, serial 465AXYnnnn. Mfg. Code is 1000010000007. I can't get it to read with anything I've got.
