[TowerTalk] Batteries For Bird 4311 - TR-169, TR-164R

[Jim Brown]

I found a Bird 4311 in very nice shape at a hamfest, and need batteries for it. TR-169 and 
TR-164R are specified, but they appear to be discontinued, and I can't seem to find any 
sort of cross reference to a current type. 

I could certainly modify the unit to use a stack of AA's, or add a power cable to run it off 12 
volts with a zenar to 5.6 volts. Are there any other good solutions?  

For those who may not know, the batteries run only the peak reading circuitry. RMS power 
measurements are passive, so I can use the unit in that mode as is. But I would really like 
to have the peak-reading capability.
