Uniden Washington Basestation, President P400. (this is my preference).
As there is a good expansion board for them plus plenty of room on the inside to put extra goodies.

Thats my preference for radios to play with anyway.

Uniden Grant MB8719pll

this unit doesn`t TX or RX. When you press the mic no TX light and when you let go of the mic no RX light. Also the meter light is dead. No RX with extension speaker either. But the PA works fine. When I turn the radio off and then back on the RX light comes on but then off straight away. Any ideas ...

And from what I think your doing, you`ll need this 1 as well.
R94 It is just above R99 and a little to the left.
