Linear Question

type of transistor in the Amp..."Mosfets" are more modern and less expencive that the older Toshiba's transistors that everyone's use to using...and can't handle volts as well...

 

They mean that it is the type of semiconductor used.

Some think that Mosfets are better but others think that transistors are better.

I think it doesn't matter.

Dealing with amps for a long long time as long as it works - who cares.

By the way, no matter what, wire the amp up using the best and thickest wire you can find for the job, don't be cheap about it. I wouldn't do anything smaller than 12 gauge wire.

 

you can actually cause your amp to overheat by using to small of gauge of wire, if the transistors are not getting the correct voltage and current they can and do run hot and overheat.

 

From what i've learned, mosfets will put out more power, but will blow quicker if SWR is too high. Like everything else now days, they are not built as tuff as the old transistors.

 

I've got a similar 1 but is only 100 watts and made by RM in Italy. You get them on ebay. Mine is a lot smaller and blue in color it's the KL 203-P

Your left switch is on/off, your middle switch is AM (CB) when down, SSB(Single side band) when up. Right switch is hi power or low power.

On the KL 203 it always operates at hi power but has a 3rd swicth for pre-amp, increasing its receive capability.

SSB won't do you any good unless you have an SSB radio.

Single Side Band CB's are pretty good, especially around channel 38. You can talk to truckers all over the U.S., Canada, Europe, N. Africa, Mexico, and sometimes S. America.

It's just like the HAM 10 meter radios. Propogation on 10 meter and 11 meter (c.b.) only works during sun light.

10 Meter is better than 11 meter SSB because Ham's have better conversations. On SSB C.B. they basically just keep calling out to see how far they're transmitting, no real conversations.

 

The HI-LOW switch regulates how many watt's your going to be broadcasting....ON HI, the linear will be doing all it can do "Full output"...On LOW it maybe only doing about half it's full potential... On LOW it won't be working as hard, and stay cooler for one, Plus if your talking to someone close by, you flip it on LOW so you don't sound all splattered in their receive.

That particular Amp does not have a "Pre-Amp" setting, so it's not going to help your receive...Just transmit...

By the way...

Not true...I have talked DX on 11 Meters way up in the morning hours all across the Country, and into Australia many times...DX doesn't always die-out when the Sun go's down...

 

The blue amp shown (mine, sold on ebay, less than $100 on ebay) has a pre-amp. The red amp does not.

Don't use the radio when the warning comes on. You need to get it checked at a CB shop or use an SWR meter yourself and tune the antenna so it gets low SWR's when the amp is both on and off.

On SSB using skip, I've spoken all over the USA, Canada, Europe, and North Africa.

On CB, I have no idea how far I've spoken because not too many people have amps and are able to answer me back.
