The 1220's stated power consumption is:

        Receive (no signal)    200 mA

        Transmit (low power)   1.0 A

        Transmit (high pwr)    5.0 A

Dimentions:  

        2.25" high

        6.5"  wide

        5.75" deep

                add 2.13" for rear heatsink if 35 watt amp is installed

                add 1" to front for mike connector 

I built mine in the evenings of one week.  It has worked perfectly and I
really do get unsolicited wonderful audio reports.  The only "problem" I've
had was a harsh vibration of the upper case sheetmetal associated caused by
mechanical energy from the speaker at high volume settings.  I cured this by
passing one wrap of electrical tape around the rear of the backplate where
the noise was comeing from.

I built it with the 35 watt amp, and found that it is possible to drill a
small hole throught the rear chassis so that final tuning can be done with
everything in place.
