Reliable communications is as much about your antenna as your radio. Any antenna is resonant on only one frequency. As you move up or down in frequency farther away from your resonant frequency you introduce an increased SWR(antenna mismatch).

Rising SWR=loss in resonated output power with some power being reflected back to your transmitter. Reflected power is dissipated in the form of heat by your transmitters power transistor via a heat sink.

SWR power loss:
1:1 swr = 0% power loss…

Transmitter – Antenna – High SWR is not your friend

I don't know what else to say other than maybe buy some. :

It's a balmy 1 degree here in central MA but feels like negative 7. That's the coldest it's been here in a few years with 6 inches of snow on the ground.

Sitting around tonight minding my own business reading email when one of them was a sales flier for a lot of different things I would like to have but really don't need. One item of interest was an inexpensive IR monocular. After Googling reviews for it, ("digital zoom" is always a red flag for me and optics) I got to wondering what the state of the art is now. With all the new tech, there should be some relatively economical devices with combination technology with starlight, IR / and/or…

Night vision, starlight, & thermal…

Well, they do have names but I guess that name might change every week or month… they'll put my name on it if I tell them to.

Many of these are exported. No microchips inside. Plain and simple, they do the job. Damn cheap too.

I am going to go looking for that large blue drum washing machine….
