Anyone got an swr meter the would like to sell to me?

Unless you’re looking for a multi-hundred dollar meter, I don’t think it’s worth it to try to buy a used meter online. This is under $30 new.

If you come across someone trying to get rid of their meter in person, go for it. But online, you might as will just go new.

 

You don't calibrate it and take it out, you calibrate it, check the swr and remove it.

 

Cheap a static meter can be found for 20 bucks at some TAs

 

I like to leave mine in just to periodically check it, but you can take it out if you would like. If you really want to split hairs, technically there is a longer path for your signal to go through so there is a very small loss in radiated power, but for CB frequencies, it is negligible.

 

Its not path lose, it's the extra connectors and resistance inside the bridge, they were never designed to be left inline.

 

I've begun leaving my SWR meter in-line after reading some horror stories about the coax getting pinched or otherwise damaged and causing the SWR to shoot up, thus causing damage to the equipment.

Although some or all radios today might be designed to protect themselves by automatically reducing transmission power in such a situation, it's always best to know ASAP when things go south. This is especially true when an amplifier is added and the transmitted power is drastically increased.

After I installed an amp in my rig, I left an SWR meter permanently in-line. Before I start a trip, I key the radio to check the SWR with the amp "off", then I check with the amp "on." It takes half-a-minute to do it, and the $25 SWR meter could save a lot of money and headaches should something get pinched or vibrated loose in the coax or antenna or whatever.

Also, glancing at the meter once in a while when transmitting will help assure you're safe.

 

What about leaving one like this in line?
