Is this model compatable with UHF CB?

MTX 838 was the export version of the MTX8000

The MTX 838 was never made for 800MHz. You'll only find it in UHF and VHF.

What's the model number of your 838? If the fourth digit is S, it'll do UHF CB straight away. If it's R, but you'll need to hex edit the RSS.

I've got an MTX838 here that's 800MHz. It's never been touched with lab. Model is H01UCC6DB3AN.

MTX838 will do all 40 UHF CB Channels, I have one myself, with keypad and all.

I have about 200 MTX838 still left on my SZ system.
I will post the model when I get to the office.

I forgot to add the system is 800Mhz and the MTX838's use mtsx rss.
The same as the 8000 and the MTS2000

I too have a 800 MHz 838, and have seen many others.

Perhaps not in Australia, but here in Canada, it's the primary 800MHz trunked radio model on privacy plus systems...replaced in recent years by the MTX850/8250.

Is it true that an MTX 838 channel switch has no stop & can keep on turning up to channel 99? GARY N4KVE

I'm pretty sure it does in VHF/UHF flavors.

Only in the "B4" model. All others (B3, B5, B7) have the 16-position selector, regardless of frequency band.

What type of trunking does the MTX838 support? type II only?

MattSR · Post by **MattSR** » Thu Sep 14, 2006 9:23 pm

Is it possible to get it to do more than 99 modes while retaining the continuous rotary? (radio is a H01RDD9DB4AN)

Cheers,
Matt

The "B3" model is Type I only...I've seen a codeplug for an "F3" model which also supported Type II.

All other models (B4, B5, B7) do both Type I & II.

I haven't seen one go higher than 99 channels with the continuous rotary, but believe there have been some posts in the past in which people claim to have done it.
