[Milsurplus] RBZ vs RBZ Special?

[MWM]

I don't think you could simply retune the 2 to 5 Mhz set to 5 to 13. I have both but have not looked inside yet but I would think different tuned circuits at least.

Subject: [Milsurplus] RBZ vs RBZ Special?



I've been trying to research what the circuit differences are between the RBZ 
and RBZ Special. The difference on paper is that the RBZ covers from 2.0mc to 
5.8mc whereas the Special covers from 5mc to 13mc. From the limited information 
I've been able to find it seems like the conversion was a field conversion that 
involved little more than realigning the receiver and changing the dial face for 
a new one. I spent some time today attempting to do just that on my RBZ and 
found that the RF and OSC trimmers would only give about +/- 300khz of 
adjustment. I'm not sure where they found an extra 7mc or so. Does anyone have 
any information or ideas?
