I suppose a guy could conceivably modify a Bradley Fighting Vehicle to use as a commuter car to go to/from his workplace. Similar to dropping a commercial radio, I suppose such a vehicle is more durable than the average SUV. But, it is entirely impractical. You seem to be fighting this thing to no ...

At least the cps for the european version can be tweaked to accept larger bandsplits; it should work up to around 500 without too much degradation.

Well I guess if display board were cheap, you could just solder on diffrent color on each and just change em out on your mood for the night lol..... Why not use multicolour LEDs together with some control unit? Then you can adjust the colour according to your mood between all possible colours by si...

But the entire point is that when you use a "real" radio and it attempts to affiliate on a trunked system, it Transmits. It is not a passive device. Yes, of course, I see the point. But it should be possible to program another repeater shift, or to disable the transmitter with the alignme...

Stick with a PRO-96 if you are a wannabe, and you are not authorized to be on the system. Otherwise, you're gunna' get carted off to jail. It is not only about trunking, the same applies to conventional operation in FM or APCO25. After being a ham radio operator for years finally I discovered the &...

Hi Ralph, during and after the charge the battery is a little warm, but not hot, so I found this to be normal, and it is a OEM battery that came with the portable. Would be worth a try charging the radio in a really cold place - if you have one :) Usually flashing yellow after a period of charging ...

The european version of this radio is called GP380.

The big problem seems to be battery contacts and cracked solder joints on the volume pots. Other than that, I've been using the Waris line since version 1.00 and love them. The battery contact issue also has to do with tolerances of the steel clip, holding the battery. A tight fitting battery makes...

The GP339 255 ch WOW !!! It would be great to have an HT1250 with 255 ch. I wonder why they only offer this in other countries ? Here in germany all the display waris radios offer 255ch, also the older MT2100 (the MTS2000-equivalent) had 250 channels. But nothing beats the XTS5k, with 512 channels ...

Hi! I have a MTS2000 on my bench, special firmware for german authorities (MTS2013-FuG13b), equipped with DVP, and it developed an annoying problem with self produced noise, opening the squelch and rendering the radio almost ununsable. My first thought was the display controller, or some ground prob...

radio-link

A major gripe with the entire Waris series, to which the GP339 belongs, is that they can't be taken out of band. Most other radios have some leeway of a couple of megs. The european waris (AE) work just fine out of band, it is no problem with a hex editor to tweak the CPS. The UHF 403-470 radio cov...

radio-link

Yes it could be. It could also be the charger, and the battery has been working and lasting fine so far. I guess I will just charge the battery until the LED starts to flicker yellow, which is after about 4 hours of starting. Anthony. Is the battery warm or even hot then? I assume the environmental...

Hi...I was wondering about the sitemaster....some people don't like them, but I wonder if they have any reference standard as to what is better or worse...they all seem to be the two-way radio types, with no experience w/ much better gear, so I cannot trust their opinion as to what they think is go...

I don't understand whats the big deal about having a radio capable of transmitting. I guess that's what it boils down to.

It is not too difficult to eventually figure out what is in the CP. Yep. On a conventional radio, it's dead easy (but tedious) for anyone with a frequency counter and a scanner that can detect DPL/PL tones. Here in germany usually 5-tone signalling is used, often with gimmicks and features being no...

Hi out there! A customer has some XTS5000 with NTN8610 LiIo batteries, together with NTN8831 chargers (the universal ones for Saber, XTS and MTS2000). Now the problem is that often the charger shows the green "battery full" LED after a few seconds, without having charged at all. The chargi...

the incomming signal has to be reclocked and resynced and then sent out. Now if you are talking about making a XL capable repeater, forget it. You would have to buy a XL capable one for BIG bucks.

We had this with european 5-tone Waris radios. Firmware upgrade fixed it, the bug also was mentioned in the readme-text of the upgrade tool.

radio-link

Be sure that no other programs are in use, especially office or mediaplayer sometimes occupy the serial port. Try to reboot the computer, keep all stuff out of the startup folder, keep your windows clean and tidy, otherwise often CPS will not work at all.

My recollection is that BX could be upgraded to CX. This upgrade required drilling a hole with a Dremel tool and changing the EPROM. After this upgrade was done, the KVL was capable of all functions except for "remote KVL" (KVL dials into KMC using a dial-up modem) operation. Since CX cou...

Hi!

Does upgrading the keyloaders also need the proper encryption hybrid? This means, does an upgrade from des to des-xl also require replacement of the des board with a des-xl board?

radio-link

When using the XTS5000 in analog conventional mode, equipped with des-xl, can I tell if some unknown stranger on my frequency uses also DES/DS-Xl, just with another key, or is the encryption system not guessable? When the other one transmits I get the flashing sign like when receiving a message with...

radio-link

Look at it this way. With IMBE digital, you have somewhere in the area of 90-95% audio fidelity recovery of the original analog signal. With Securenet, you only get about 65-70% recovery. A little difference (pre/de-emphasis) in the analog audio can mean a big difference in the audio fidelity recov...

radio-link

That's because in "Apco" mode it's all digital. The filter issues you mention aren't a factor since they aren't used. The vocoder takes care of it. mancow Yes, of course; but in securenet mode also everything is digital (just another codec and bitrate), so I do not see there any differenc...

radio-link

The pre / de-emphasis is applied to the analog signal, both before & after the IMBE conversion, so it would have a significant effect on the audio, regardless of what modulation you are using. Todd The funny thing is, in APCO mode (with IMBE vocoder) nothing can be observed, no difference at al...

Hi out there! Today I had two XTS5000 on the bench, and the user complained that on some conventional channels securenet operation (DES-XL) gives better voice quality than on others.

Hi out there! I just wanted to confirm that it _is_ possible to program the XTS5000 with a selfmade level converter. It took me a MAX232, a 78L05, five capacitors, the connectors, and there it was - the selfmade programming interface! Just different pinout, compared to Jedi radios, and 4 data lines ...

Hi! I wonder how it could be possible that no one ever was able to trace the communication between KVL and radio to find out how they talk to each other.
