Question about Radio Communications
I have a 101 bear cat scanner it works but it dont work as good as it should, the u h f band works but is scratchy and has a hum in it when some one talks. and the signial is week on a close dispatch. the v h f works good and clear. can any one work on the u h f part of the bear cat 101 and make it work better ; thanks Norm
First of all check the antenna connection, it could be dirty which causes more impedance at the higher frequencies than at the lower ones (uhf is higher than vhf), also hum could come from a power supply that can't produce enough current, does it get worse when you turn the volume up high? if so and you use a wall adapter, you might need one that has the same polarity and voltage but a higher current output, such as 400ma compared to 250 ma. If the power comes from a standard ac cord without the transformer (cube) at the wall outlet, then the internal supply might need a new capacitor in the filter circuit.
