I think OP was referring to the fan in his bench power supply was still running (IMPRES battery backfeeding).

Thanks. I didn't follow the golden rule of forums, "Search before posting".

We were using a free site to create voice announcements for MOTOTRBO 2.0 radios (CP200d, XPR3500e) but that site has some security issues.

What do you guys use to create voice files that aren't huge (CP200's don't have a lot of memory).

Thanks in advance.

I found the service manual. Dated 1993. There is no reference to programming anywhere. I'm sure the frequencies are hard coded into it.

RFguy

There is no jumper required. The external speaker runs in parallel with the internal speaker. Just hook up the external speaker to pins 1 and 16. if you want to disconnect the internal speaker, you need to cut jumper JU501 or disconnect the internal speaker at the speaker. Note: The M1225 only suppo...

From what I recall, it's pre-programmed from the factory for the standard marine channels (just like most marine radios) and not field programmable. I had a manual at one time, but not sure I could find it now (if I still have it).

We had a discussion at work the other day and this subject came up. I've always used Return Loss in dB when sweeping an antenna. Someone else suggested using VSWR. I've never found VSWR very useful as I can't easily related it to anything of adjust for things like feedline loss. For example, if I ha...

RFguy

No.

You have a choice of high power and low power. You can set each personality to either high power or low power.

Unless these are the only frequencies in a certain frequency segment in which case you "might" be able to play with the tuner for that frequency segment.

RFguy

Are you still looking? I'm sure I have one and can scan some pages.

RFguy

In the past I have used a different PL on the RX and TX frequencies of a repeater to head off issues on installs that were at risk for intermod. It was a bit of preventive medicine, but more of masking an issue rather than solving it.

RFguy

I always assumed they were marks made by the people assembling and testing them marking completion of different stages.

RFguy

Just an FYI for those that want to find someone to fix a IFR1200

Contact Kurt at KG Electronics
https://kgelectronics.com/

He has repaired several for us over the years. He does a great job at a reasonable price.

I believe he only works on 500's and 1200's (not 1000's, 1600's or 120's)

RFguy

Yes, everything "could" be reused. Should they is another question.

Factors such as age of the existing feedlines, current condition, how critical this system is to your operation all would factor into it.

RFguy

I've used Label Graphics for pager labels in the past. Not sure if they do radio labels.

We have used the VX-4600 radios for packet use in the past. We had no issue with RX audio on pin 2 of the rear connector.

RFguy

Motorola has, and continues to do a very poor job of communicating any useful information for the configuration and use on MOTOTRBO radios. We had a customer requesting some training info to help train their users on the proper use of the radios (mic placement etc). Motorola could not provide a sing...

RFguy

Looks like it was a configuration issue with a missing repeater in the codeplug. Can't blame this on the firmware.

RFguy

We are seeing an issue running 2.09 and 2.10 firmware on XPR7550e portables accessing a Capacity Plus repeater where the repeater is running an older version of firmware.

Updating the repeater firmware is problematic due to access issues.

I was wondering if this is a known fault.

RFguy

I don't have an answer on your problem, but if you want to send it for repair, I highly recommend Kurt at KG Electronics. He only works on IFR1200's

I just realized it's been a few years since I've seen a service bulletin from Motorola.

Has anyone seen any in the last 2-years or so? If so, where are they located now?

RFguy

I found the answer. Hytera.

They have an import utility. A simple spreadsheet/CVS file.

It's disappointing that Motorola doesn't have some method to import channel info into their radios.

RFguy

I have a requirement to program a XPR2500 or a XPR5550e with 100+ conventional channels (it may end up being around 200 channels). Are there any shortcuts? I would love an import utility to import a CVS file with RX, TX, PL tones, alias etc. Anything to keep me from spending a few hours entering and...

Is it normal for HT battery voltage to be present on the XTVA power connector when disconnected from main power? Yes, when using an IMPRES battery. I dealt with this before. The XTVA was designed before IMPRES and wasn't changed to prevent back feeding. It's all good as long as the main power is co...

RFguy

LTR data levels are fairly critical. Are you running wideband or narrowband? Narrowbabnd LTR levels ate 700 to 800 Hz deviation. The LTR data from the controller to the repeater needs to go into a flat audio input, typically DC coupled.

I have a customer complaining of the same issue (spiking RX audio) using Peltor headsets. It's operating on a Cap+ UHF repeater. We have been unable to duplicate it in shop. This is on a XPR7550e radio.

RFguy

What do you mean by spikes? Is it on RX or TX? Is it always at "that" level, or is it different at different times? Are these surv kits Motorola units (digital certified) or aftermarket units?

RFguy

Maybe this?

1137 = 2011, 37th week

1386 = 2011, 38th week, 6th day of the week

I've dealt with this before and made some notes. Accessory and Battery 3-digit date codes: The old Motorola date codes are 3-digit long. The first digit is the last digit of the year. The last 2 digits is the week of the year. Example Date code 245 is 2012 45th week There are 3 formats for 4-digit d...

We are just using standard 7.2AH, 12 volt UPS type batteries with some foam packing around it. The originals were only 5 AH, so it gives a bit more run time.

I consider myself very proficient in 2-tone paging coding. I started in pager repair in the early 80's and we have run a carrier system ever since, but I have never understood diagonal codes. Maybe it's because I have always worked on Motorola pagers and not some of the other brands that had alterna...

The DTR550 and DTR650 radios have been cancelled. Apparently there is a replacement going to released in a few months, the DTR700. It's "supposed" to be backward compatible with the DTR500/650's. I found this info on it. https://www.radiotwoway.com/Motorola_DTR700_New_Portable_Radio/amp https://www....

I was thinking of quoting a SLR1000 in a application that we only need a single talkgroup range improvement.

Does anyone have any experience with the SLR1000 in the extended range direct mode (Simplex repeater) application?

Thanks in advance

RFguy

I found a AAH25KDF9DP7AN model. Is it possibly this?

If so, it's 32 conventional channels and 15 talkgroups (LTR)

RFguy

Do a quick test. Transmit on the speaker mic, while holding the PTT button down, turn the radio off. I suspect the radio may not power down until you release the PTT button.

This may help prove it's a bad mic.

RFguy

Also try another tone (if possible). Maybe a lower tone like 77 Hz, or a higher one up around 200 Hz.

Some radio models do better than others at certain frequencies.

RFguy

I don't recall the name/part number of the software, I just remember the exe was radmbl.exe

RFguy

No. they won't go to 30-36 MHz. It's a completely different RF board design.

RFguy

Has anyone seen any test sets for the XPR/SLR repeaters? I know there is limited functionality in Digital, but we will often program a repeater to analog to perform testing such as site noise testing. I'm thinking of something that gives RX audio (possibly speaker audio) and a microphone connector f...

RFguy

Thanks for the replies. It gives me confidence to move forward with a test.

One thought here is just to use a USB cellular modem "Rocket stick", but I like the idea of a good quality Sierra modem/router. It allows for an external antenna and probably a some management features.

I don't see a market for a "commercial" (non public safety) dual band radio. It just never comes up as an issue. I suppose if there was one at the same or close to the price as a single band, some might buy it "just in case". With such low demand, I don't see any of the major manufactures producing ...

Is the XPR8400 running in analog or digital mode?

I would start with programming a second channel in the repeater in analog mode. Channel steer to that channel and do a full set of tests (site noise, TX desense, co-channel interference etc).
