Even with off-the-shelf radios, some electronic theory
is necessary to use them properly and effectively. For example, how does one use the IF Shift control? Know how a receiver works allows one to use this feature better. There are many such example. Antenna tuning, notch filters, SSB filters, etc. More below. Doug, k3qt s/v Callista "Vito" wrote in message ... "Doug Dotson" wrote "Vito" wrote It's inevatable because of technology.

To protect selfish bad-fist rag chews from interference, that's why. The CW portions of the bands are pretty narrow. Wideband traffic just chews up too much of the designated band segments.

That *was* absolutely true back when we built our own gear, but one needs no knowledge of electronics to use, say, an Icom 706 with an automatic antenna tuner. I don't think so. I have gotten zapped several times by off the shelf rigs. Might be useful to know why you got that nasty RF burn. Everybody is an "appliance ham" because it is too expensive to home brew.

I guess they're all into instant gratification. Putting together a kit is not homebrewing in the normal sense. I routinely solder very small surface mount chips onto boards. It can be done very easily with solder paste and a toaster oven. The touching up with desolder braid and a small tipped iron.

Knowing a formula and how to apply it are different things. When I was in college my physics instructor allowed us to bring a sheet with any formulas we wanted into an exam. Some folks still failed the exam though. |
