Stock 29/78XL question

[Marty]

I bought both of these radios several months ago at a big box store. one for the base and the other for the truck. I know they are 4 watt radio's. What does one of these do on a high quality meter like a Bird meter with the stock microphones?

Dead Key = ?

Modulation = ?

Thanks Marty

You will need to have them tuned up first.

You should see about 6 to 8 watt dk. about 40 watt pep on a bird 43p. good luck.

With the radio as is what does it do? 3 watts dead key - 4 watts while your talking?

 

[Switch Kit]

could be 3 to 3.5 could be 4 or 4.5 to 6 to 10 pep on a whistle ,talking would be less, at 40 to 80% modulation,.Some do more and some do less out of the box , with a tune up at 100% modulation , 5 to 6 to 18 to 24 watts pep ,on a whistle , IM sure talking would be much lower less then that. IM not sure what 626s numbers are. Mine are ballpark.

I remember my old peak and tuned 1994 Uniden i can't remember the model but it look like the 78 XL with the swr meter, etc. it did 2-16 watts at the CB shop but it put out 20-22 watt's peak on my 20 dollar Radio Shack meter. Both where whistle test.

 

[freecell]

per FCC Type Acceptance:
@ 13.8VDC into 50 Ohm
resistive load.

Dead Key = 4W

Modulation = 12 - 18WPEP

Very interesting freecell, I was just looking through the new easy to understand FCC rules booklet that you get with the newer radio's and it said ( 4 watt carrier) but doesn't say anything else i wish the government would make thing's easier to understand.

73's to you and your's 8)

average
dead key = 5 watts
whistle = 6 watts

PEP

whistle = 14 watts
