the antenna is about 37.5 inches and its 1"
X 3/4" x 3/8"
Did you use a frq. counter to determine the operating frequency?
37.5" migt indicate a 1/2 wave antenna at 143ish megs or a 1/4 wave at 71ish
megs - it might be a 'standard freq'.
The AH13 battery - although it's Lythium - makes me suspect it's 'spy shop'
cheapo stuff. Is there an adjustable cap or ferrite stub - it would indicate
an FM LCO which would fit the 1/2 wave
