Think Ham is hard?
 



I never want to hear you guys complaining that you need a more power or it's too hard to understand PL tones or repeater offsets...

This 9 year old girl (with a some help from dad) is building a hasty QRP CW transmitter. I don't know what she is building exactly, but my guess is one of the hacked radios that use the guts from an audio gadget (like an old Walkman) or 74xx family chip. You can see the schematic for a second at the very start of the video.

You can use just about any logic chip to make an oscillator that will work on the MF and low HF, 160m, 80m, maybe up to 40m bands and might radiate a watt or two, which is enough to talk hundreds of miles, with maybe a dozen parts. No soldering required even. Gotta know Morse, though. I'm working on that...

Ultimately it's all about the antenna!

what's hard is.... to watch that listening to the titanic flute. I only made it like 1:30 before I had to shut it off :D

Morse
 
The best way to get to know Morse is to have a QSO with another op. String up an inexpensive wire antenna and listen for someone calling CQ then give them a call. No backing out or changing your mind-you've got to make it happen. And, yes, your investment has got to be in your antenna, no ifs, ands, or buts. CW is where all the action is!

As long as he does 'a', 's', 'o', 'e' or 't' I'll be fine. :-) Differential equations was a snap compared to learning code. Really. I'm not good with languages. Tried to do German a couple of years ago and I just don't pick them up quickly for some reason.

Cw
 
I like to hang out on the CW portion of the bands because of the challenge CW presents to me. I, too, could never learn a foreign language. CW is the closest I could get. It's still very much a challenge for me today after being on CW for 37 years. I think it was Winston Churchill who said "Play for more than you can afford to lose and you will learn the game." I think of that quote every time I fire up the rig. The challenge is huge but the rewards of making a CW QSO are even bigger. I hope they never take away our CW band privileges because of a lack of activity.

I made it to 1:40 but spent my time reading your oter posts. Bruce as much as I'd like to learn Morse I just don't have the energy to put towards it.

code is easier to capture than to send. not that I would know...

Using 100mW to communicate transatlantic, the power of HF!
