Sorry, and apologies for the extra email, just wanted the info to be
complete.
The "3" near the end is the range - 1=403-433, 2=not used, 3=438-470,
4=470-490, 5=490-512
Awesome radios.

I think you mean M44GMC29C3AA's - tons for sale on eBay typically
around $50 each.
M = mobile
4 = 25-40W (20% duty cycle)
4 = 438-470 Mhz
GMC = this series (actually German Maxtrac is where these came from)
2 = wideband deviation (5Khz, where a 0 would be 2.5Khz narrowband -
not switchable, one or the other)
9 = expanded logic board - 16 channel typical, MDC1200, QCII, etc
C = model revision
AA = not used, just character filler
Are you power cycling the radios or the Zetron?

Is the Zetron that's locking up? I had a similar problem with a
Zetron 45B.

We have 2 repeaters that are more or less the same. One is on 2
meters and the other is on 440. They both exhibit the same
problem, they lockup after a while and then need to be power
cycled. They ran for years without issue.
We have the Instruction manual for the Zentron controller, but
nothing on the radios. The 440 radios are Motorola M44GM29C3AA's
back to back. That's the only model number on the radios. Does
anyone have any information on them? A Google search shows 2
Chinese sites having them for sale on e-bay, that's it. Seems
strange.
Any information would be greatly appriciated,
