Saber Out of Band Question....

Post by RadioNut »

I have read the: Notes on programming Sabers out of band. But I need a little guidance.

I don't quite understand what I am reading. My goal is to get a few freqs in the 144-145mhz area on my saber (146-174) range model. My programming guy is willing to do this if he is informed on what to do.

He is not familiar with this and does not want to be responsible if it "kills" as he puts it, my radio...

Can anyone assist me?

** NOT ASKING FOR RSS FILES....JUST HELP WITH WHAT I AM READING **

What I don't get is where it says to "use a place holder frequency"

Thanks

It's really quite simple.

"Placeholder" means you put in a valid frequency as a temporary placeholder for your real frequency. Say you had a channel that had a transmit of 144.5 and a recieve of 145.2 - the RSS will not allow you to enter 144.5 (on 146-162 radios, it will let you go 1mhz out of band). So let's say you enter 145.0 as a placeholder.

Now you go through the hex editing process on the codeplug file as detailed in the saber page, and you replace the placeholder frequency with the real frequency.

Just remember as per the warning on the page, that once you do this, when you read the codeplug file, if you view the hex edited frequencies it will reset them.

Good luck.

It is much easier to just hack the RSS itself on the hex editor to change the bandsplit than do each frequency in the codeplug... plus you run less risk of ending up loading a bad codeplug into your radio.

Follow these steps. I have done it no problem..if you need any help just email me [email protected]

Is the radio a standard Saber, or Systems model?

If standard, then no editing is necessary, just enter the information and program/align.

Systems Sabers are touchy and will NOT program below or above the RSS defined band splits without editing the CP or hexing.

Standard Sabers can easily be programmed well outside the split 'IF' you have the proper modules installed in the radio first.

If this is VHF, and you have the NLD8201 synthesizer...dump it and replace it with the NLD8210, this one will allow programming down to 140 and well up past 170 Mhz.

The UHF models will also operate outside the 'intended' split, but not 'that' far.....Say +/- 3 Mhz. which is usually more than enough fudge factor for 99% of the crowd.

Also, wth the Systems Sabers, if you intend to use status messaging or text, be prepared to have a PL inserted on ANY frequency you tune to, including all CSQ channels; it's S.O.P for this radio to perform this whenever status messaging/text is selected.

I had this happen several times before I 'found' the cause, so be forewarned if you make use of channel with CSQ on RX.

You will see the PL indicator pop on even if you are on 446.000 direct, or any channel with CSQ when you have status message/text enabled and keypad selectable.

Its a standard Saber I nothing fancy and I just need it to go down to 144.570 for one lower freq repeater. Thanks for the info. We are going to try everything tomorrow evening.

Does the "trick" of programming a High power Saber as a "Low" power Saber (VHF to get below 146.000 MHz) to get the lower bandsplit work? I've heard that keeping the radio's alignment settings and inputing the 144-146 freqs as a low power still gets you high power but a couple more MHz programmed for ham use.

I'm curious as to which modules he has in that radio.

If the synthesizer is the NLD8201, then he's pretty much stranded in that band split, but if he has the NLD8210, then he has 'options' to program the radio all up and down the band, below 144 and up past 174.

Of course, the other modules must be checked as well, like the 5-pole filter under the receiver, and the 2-pole on the upper right, as well as the F.D.S (Filter, Detector, Switch) and also the proper PA module for the wider band split operation.

If you are directing your question to me, I could not tell you which modules I have but, we did get the Saber to accept down to 144 by using the above "trick" of modifying the actual RSS Saber.exe file.

It was quite simple. I forgot to post back here and was reading and remembered that I had asked about this.

Thanks for the help all.
