Re: uBitx Antenna
#ubitx-help
Is it still an available meter? Is there an eBay/Amazon listing. If you have tested it against a known good SWR meter, I'd like to get one, if it is still at a good price. Tom, wb6b

I have a cheap CB swr meter (just swr not power meter) and a crossneedle ham-meter. In the instruction sheet they say it is usable between 1.8-30! They are liers!!!! It works from 1.8 to 50Mhz (yes up

45M Filters
Folks! Although this is the cheapest filter for 2 bucks, I hear only mention of people here buying more expensive ones.

I like that statement. Was just reading an "authoritative" article repeating the standard "maximum power is transferred when the load matches the transmitter impedance" and that was why you had to

Re: uBitx Antenna

SWR and Wattmeters made for CB are often worthless in the ham bands, unless you're only using 10M. I picked up a Firebird SWR/Wattmeter a while back that was supposed to be good for 1.8-30 MHz. HAR!

Re: uBitx Antenna

Dan, a CB swr meter will probably give you an incorrect reading on any band except maybe 15 or 10 meters. A nice, relatively inexpensive new SWR meter is the MFJ-818, correctly constructed for all the
