I would argue that drawing a schematic for an oscillator is pretty much rote memorization. 4 years ago when I took my Extra written, it was certainly not mostly memorization unless you mean memorizing the test bank. I found it easier to learn the theory. The impedance calculations and various other items did take some effort to learn. 73, K3DWW |

"Tap code" is better because it is easier to cypher & decypher and most important requires only "dots" vs "dits" and "daws". Simply write the alphabet in a 5 by 5 matrix, leaving out "K" (substitute a "C"). "A" is dot-dot. "C" is dot---dot-dot-dot. "N" is dot-dot-dot --- dot-dot-dot, et cetera. Easy to send with a hammer or whatever you have. To decode just right what you hear then turn to your matrix: 2/1, 4/5, 1/3, 5/3, 4/5 ....

If Morse is so much more reliable at getting messages through, as every ham believes as fervently as Billy Graham believes in God, then why do we need special bands to protect CW from "less reliable" modes?

I could have bought a kit that's not as good for $1250. Sorry, but I'm not so well-off that $750 isn't important. But you are certainly right about the lack of skills. I don't know a single ham who has the equipment needed to micro-position chip componants then wave solder them, let alone the skills to use such equipments - including yours truly. I guess they're all into instant gratification. IMHO homebrewing, not Morse, seperated us from the instant gratification crowd on 11 meters. Nobody morns it's passing more than I.

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. |

: I think CW is still more reliable than phone, but certainly not more effiecient nor is it more practical. I've been listening to this crap since SSB came out..... In 1949, it may have been true. But, I tell you what.....Go download WinWarbler: http://www.qsl.net/winwarbler/download.htm for free. Install it, then simply plug your soundcard's audio input to the headphone jack on any SSB radio set to USB on 14.070. Pick the faintest PSK31 trace you can find on that display and click on the trace. Winwarbler will print perfectly on a signal NO CW OPERATOR COULD EVEN HEAR. Most PSK31 operators never run over 10 watts. PSK31, by the way, is NARROWER IN BANDWIDTH than 15 wpm CW! Winwarbler, just to show off, will copy THREE SIMULTANEOUS frequencies inside the SSB rig's 3 Khz bandwidth this way. That old CW-in-a-pinch nonsense IS really nonsense, now. Anyone in their boat's SSB that wants to see what's going on can download Winwarbler to their boat laptop and tune the Boat SSB radio to USB on 14.070 Mhz, where 90% of the PSK31 traffic occurs. On Lionheart, I don't even have to connect the M802 to the notebook! The notebook's built-in microphone can hear the radio's PSK31 warbling tones and prints them perfectly if there's not too much conversation going on around it! PSK31 is the most uncanny form of HF communications ever invented....and it was invented BY HAMS FOR HAMS. Sorry you're stuck on SITOR clicking and clacking away.

There you go again Larry. My comparision was between
CW and phone and you bring up PSK31 Now that I think of it,I have tuned into CW signals that I could hardly hear and was able to get the computer to pull it out pretty sucessfully.

Doug, k3qt s/v CAllista The computer isn't anywhere near as good copying CW in noise as it is the phase-shift (FM?) keying of PSK31. Simply amazing how it can copy signals too faint to even make out with your ears.... 73, Larry W4CSC |
