Looking for Cherokee Nighteider 150 mods

[hackindave]

I tried the search function but couldn't find anything on the Nightrider 150 as far as channel mods and other mods go.
I just won one off of E-Bay and wondered what its capable of doing. It has the MC145106 chip same as the newer 148GTL-DX but without the 2 adder chips..

Any help will be appreciated...channels, power mods

Nobody knows of any mods for this radio?? Is it not modifiable??

If the MC145106 PLL chip is accessible, this means that the 18-pin Z8 CPU on the channel-selector board is also accessible.

Every NR150 I ever saw had the PLL chip and the CPU globbed together on the main pc board under a layer of hard epoxy.

This was done precisely to prevent frequency expansion. The FCC would have never approved it for sale as a 40-channel CB without that 'feature'.

If yours does not have the potting compound, there should be a tiny jumper wire on one rear corner of the channel-selector pc board. This is the same channel selector as the North Star radios used, and the same jumper instructions should work.

Like for this one: http://www.cbtricks.com/radios/northpoi ... _early.htm

Or this one: http://www.cbtricks.com/radios/northpoi ... q_conv.htm

Just never saw a NR150 that was built to permit access to this feature.

This is the Northstar photo. The NR 150 is below. So if I cut the trace, I should get extra channels?

If that doesn't work, is there like an expo kit that will work??
