Pre Amp

Thanks the station here is set up for HF/VHF/UHF. You can find me on CB early on weekdays or sunday mornings and just about anywhere else at other times.

I got started on CB and never left it ..........

The bigest lie in ham radio is ..... I never mess with CB .... YEA RIGHT ....

 

That's the truth i have a cb hardley ever use it but i do use it from time to time. Hey do you run APRS and if you run HF try us on 14.302.5 trying to get the band back going before i went over to Iraq we had 20 or 30 truck drivers there and allways had a good time chatting as we rolled across country.

 

I run some PSK-31 on 20 meters but right now time is the problem ...

If your on 20 on sunday mornings lissen for me on 14.300

 

Does having your preamp off effect the power output of the amp itself? I’ve got a TX-100 amp running into a Cobra 25 LTD Classic that’s been peaked and tuned. The amp has three switches. Amp, Pre, And SSB.

 

No

 

What exactly does the preamp do?

 

It amplifies incoming signals but ... there is a problem with a bunch of them that were sold, they have noisy transistors/fets and poor design that allows higher gain than is needed which causes more issues.

 

They just amplify the incoming receive. Noise/static and everything else.

You hear a distant weak signal and decide to turn on the preamp, bit they are still hard to hear because the noise/static is also louder. It's still the same situation in the end.

Sometimes at night, after the sun goes down, they can be useful. But IMO it's a rare occasion.

I would still prefer something with a preamp, but wouldn't go looking for it... Not much to miss without one.
