Batboard

You might check the old Batlabs for some info on that

Hmmm..... IIRC constant tone usually means the channel isn't programmed....

Ive done bunches over the years. Once you've done the recrystalling you would need the radio to reinstall the TCXO and retune and recalibrate the radio with a calibrated service monitor. Ive bought crystals and had BOMAR or ICM install them in the TCXOs I supplied (especially MX radios). I still had...

At the heart of an APX radio lies the MACE security chip. The MACE is an on-board radio encryption device providing cryptographic services for all voice and data communications. It also provides a secure environment for storing encryption keys via a hardened tamper-resistant chassis that’s FIPS 140-...

Might try your question over at the Radioreference.com website Lotta folks with Unication pagers over there
Good luck

Post is 3 years old dont know if the OP is still around.....

Could be a ground plane issue with the Waris and those antennas. A field strength meter would be helpful. You could use a VOM with a diode between the leads for a crude measurement device

abbylind

Harris Orions and M7100s can put 2 radios together with one control head. Mating the Pyramid shouldnt be too difficult in that mode.
Glad you got it worked out for your XTLs

abbylind

Thats definitely ignition noise. Spark plugs (must be resistor) ignition wires, yours has the coil over Replace them. Look for loose or corroded connections. Dont disregard the connections for the tach. It takes impulses from the ignition. I had a poor connection on the tach caused lots of emitted R...

abbylind

IIRC R100 repeater
There is also a reference to the HT600 RIB interface...dunno about that

abbylind

I bought one that looked that way too. Thought a painter used it. Bought a new plastic housing, looks great. If you go that route dont forget to order a new display cover, it doesnt come with the housing

abbylind

You might try Bomar Crystal They might be able to run it down for you sir

sales@bomarcrystal.com
Good luck

abbylind

No joy sir sorry,,,,,

What is the actual freq stamped on the Xtal? Not the 43.000Mhz
May be able to back track the formula using the Xtal freq. Sometimes the Xtal goes into a TCXO

I think thats an RCA mike from the 60s. 1960s and 70s RCA and Dumont radios look very similar. A friend had an old Dumont VHF portable it was a clone to the RCA. I had a RCA TAC 100 CVC the mike looked like the one in the pic

abbylind

Heres some GE RCA Aero stuff

Dont know if he needs the info anymore....post is 4 years old....

MT 500 I had one that burned inside a Converta-com in a car fire. Used a crow bar to pry it out of the CVC. Wiped off some of the black char, turned it on and viola it worked!

abbylind

Replace electrolytics , A lot of wires lose their insulation so you should check them. Some resistors break down over time too. Transformers can short internally. I restore a lot of old vacuum tube radios and electrolytics are first. I also use a variac to bring up power. Start with 20 volts and go ...

He has lots of great info on vintage Motorola gear

abbylind

Thanks Dr Alex!

abbylind

Darker brown color.....sounds like Sinclair cans..

abbylind

I didnt make radio stickers but Stickercutting.com made some custom stickers for me.. Nice work reasonable cost Ask for Jason
Good luck

abbylind

Its not a 220...Looks like an old Repco...Brass? who knows why.....?

abbylind

Nagra used to make similar recorders in the 60s. They were designed to put out a taped message over the police channels. They were placed in locations that were prone to robberies ect. When the clerk pulled the switch it instantly went out....decreased the response time going through the alarm compa...

abbylind

We used to Pledge the plastic and fiberglass on our Police bikes for years. Works great and covers a lot of scratches...YMMV

abbylind

Try a different radio. See if it acts up too. If its only on one frequency it could be the reference xtal on one of the onboard CPUs. We used to pad the xtal in the cpu with a small cap soldered to one leg

abbylind

ICM quoted me $25.58 each for xtals only (Id change out xtals using the old TCXOs) for a MT500

abbylind

Try this...

Hey remember Permakay filters have a lifetime warrantee......

abbylind

Try Tessco they have several models

F

abbylind

Looks like a DB-404 or a variant thereof....

abbylind

The purple features makes it sound like a XTS3500....

abbylind

Nice resto!

abbylind

MTSX Lab is DOS

abbylind

Yep it can be done Need MTSX Lab software and a II codeplug Not for the faint of heart though Screw up and you have a brick
The P25.ca website is a wealth of knowledge

Dont tell me but it must be "Sanchez Fe County"

.....good luck

In the battery mode it adds a rodger beep after each transmission

abbylind

Installed a 240GB SSHD in my TB Runs and boots up a LOT faster Still running XP in it
YMMV

abbylind

395Mhz? You might want to check with the AFB most of those are AM freqs in that range

abbylind

Ditto Never saw a low band HT220 Saw some MH10s Handicoms and PT series in lowband

abbylind

I picked this one off a 77 Ford F150 as an example

Used to use the starter relays in older Fords. Try NAPA or an auto parts stores. Should be fairly easy to find.

abbylind

Had a converta com (dating myself) It would flash on charge until you pushed the PTT on the mike then it charged normally...sounds silly but have you tried that?

abbylind

D
Two Yagis phased 1/2 wave to full wave apart..... 75 ohm cable from the antennas to a tee connector 50 ohm from the tee to the radio.....viola!

F

abbylind

Dave
You could stack two yagis but they need to be co phased

abbylind

Nice to see someone else in the NM area on Batlabs. Nice install!

abbylind

And.......check your mike......try a different one.....

abbylind

You might also check your battery. If its failing more strain on your alternator. If all this checks time to check your alternator. You may also install a whine filter inline with your radio power lead. Try this..... http://www.worldwidedx.com/home-brew/31492-building-simple-alternator-whine-ignitio...
