no Heil microphone

Hi Ray. I've always wondered about those... Transmitting a 3KHz wide signal with a $500 (or more!) microphone has me baffled. Of course, they often use more than 3KHz, but even then... I remember paying $2 shipping included for two microphones for my KX3, the computer type, from China. I got great audio reports :o For my KX2 I use a cheap Astatic, though I might make a smaller microphone, just an Electret capsule and a small button... I doubt the extra money spent on a studio quality microphone helps to communicate. I think of my RT-320's punchy "military" audio with not too much bass and good compression, with a 25 handset...

I just got a ZLP MiniProSC interface and was looking at FSQ... Then I thought, why bother? I know Morse code. FSQ might be more efficient for weak signal work but like you point out, the extra gear isn't worth the trouble. I'll use the interface for Winlink and that's pretty much it.

Given the cost of CW radios, starting at $3.50, and $50 for a great 1-Watter, the choice is easy. Preppers are not all into radio and Morse can be used so many ways...

Hello,

Here is an easy project involving a BNC connector, small plastic box and eighteen 100-Ohm 2W resistors. Total resistance is of course 50-Ohms. What is the total power handling?  ;D

When I first got interested in amateur radio, I thought Field Day a great concept - but when I saw the vast setups people were using - trailers, generators, HF log periodics etc.. and heard the 599 contest contacts on the air, it wasn't for me.

Field Day is no longer about getting out of the shack, it's about getting the shack out...

Your project is making me want to find and finish my 80 meter SURVIVOR. for camping.

Excellent!

They are sending me a return label for the 5-pin, darn :( Oh well... Waiting for the 6-pin now and the microphone...

My 80m 1-Watter has a transmit issue... I hate troubleshooting...

Thanks Ray. I am hoping to use one on two extra pins to turn the radio on, to avoid drilling an extra hole for a switch. That way the radio would turn on when the mic is plugged in...

Thanks Scarr.

I got the case today. It looks to be just the right size with room to spare for batteries and the DDS/Arduino combo.
I also got the BNC and audio connector but they sent me a 5-pin instead of the 6-pin I ordered. The replacement supposedly will go out today, and it seems I get to keep the 5-pin one ;D I might use it for other functions, maybe charging... The Thales microphone is on its way. Time to look into programming... ???

Yes, I need to try my PRC-352 again, but 6m FM is hard, too few people using it...

Good one Sparks. I used Ham University on iOS and KMTPro on Android. I like the feature that lets you listen to current news in Morse code...

Yep, they sell balancing charger boards on Ebay for a few dollars. I just charge them out of the holder...
