Outboard speaker

[William E. Twaddell]

Looking for an outboard speaker for the K2 sr# 1837.
Any suggestions.
There is one in QST but it is very pricey.

Bill,

Look for an efficient speaker, and a 4 ohm impedance will give you twice the
audio power vs. an 8 ohm speaker.  Most common speakers are 8 ohm.
 P=V^2/R - the driving stage determines the V^2 value (the LM380N is really
a special high power op amp with a low output impedance, so the voltage
developed at the output does not depend on the load until the load
resistance is very low), but higher resistances mean less power will be
developed across the speaker.

73,
Don W3FPR

Any place you can find a used Motorola mobile radio speaker, grab it.
It will have good audio, and plenty of output.
Good luck and 73
