XTS1500 q SPILT TO 440 ?

[E5911]

I have a XTS 1500 H66QDC9PW5AN uhf DOD Q split radio. I use it primarily on a allstar Node at 433.1
It has Firmware R09.00.41 and tuner R01.08.12. The CPS will take the programming in the ham band and write to the radio without issue.
I can TX at 446.0 with no issues locally. Is this a boat anchor ?
One issue I am having is the radio works for a time and then I get a solid TONE emitting continuously until I turn off the radio.
The issue happens when I'm on the node at 433.1

Isn't a Q split 380 to 470MHz? That should work fine at 433 and 446MHz.

Q is 403-437MHz.

The radios will usually go out of band a bit, but get to far and the VCO will unlock and the tone will sound. Sounds like 446.0 is right on the edge and it wobbles in/out of VCO lock.

Not sure about the XTS, but on some older radios you could retune them to squeeze a bit more range one way or the other.
Other option is to swap out the RF board. But getting the correct RF board usually requires buying a whole radio, at which point it's just easier to program that one up with what you need.

Q on astro25 radios is 380-470mhz. That model will most definitely do 446.mhz

Q is 403-437MHz.

On a Jedi it is. 4 splits to do all of UHF. On Astro Sabers, XTS3000’s, & newer, 2 splits do all of UHF.

I've bought clean XTS2500 model 1s with a 380-470 split on Ebay in the $40 range. You can also get full keypad model IIIs in 380-470MHz with FPP and AES for about $125 all day long. No need to suffer with a radio that won't do the entire amateur band.

I believe you, but one of my manuals shows the XTS1500 Q as only 403-437…. Maybe it's old.

After further checking, it appears the vco is unlocking or I have a bad capacitor
Radio is going to the parts bin, not worth selling.
Thanks

XTS1500/2500/5000 radio Q split is 380-470MHz

Looks like there are differences between the model nomenclature and the specs. This manual, p. 15, says the "Q" in H66QDC9PW5AN means 403-437 MHz range, but page 18 says "range 1" radios (FCC ID AZ489FT4865) are 380-470 MHz and page 19 says "range 2" radios (FCC ID AZ489FT4866) are 450-520 MHz. Pages 20-24 show only "Q" models as 380-470 MHz and "S" models as 450-520 MHz.

[Add] Just to expand, the model nomenclature shows 4 UHF bands: P=336-410; Q=403-437; R=438-482; S=470-520. There are also H and T "Product Specific". Not the first time I've seen this sort of thing.
