D-104

http://www.qrz.com/iB_html/non-cgi/emoticons/sad.gif Unscrew bottom cover... check the connections... I can key the radio up. ... BUT it won't pass the audio. I futher checked... took the relay out of the tube... Oh my. http://www.qrz.com/iB_html/non-cgi/emoticons/tounge.gif

Took my 30 mins to fit it back in place http://www.qrz.com/iB_html/non-cgi/emoticons/mad.gif

Ok. So much for making a foot switch for it.

I was trying to get my foot switch to be used as a ptt switch for my d-104

[K5USS]

Huh? What is the issue?

[W6ECE]

What did he say?

[kg4kww]

W6ECE -- he said he has GAS!!!

[ai4ep]

... ( sarcasm mode ) ...a foot switch for a microphone ? Are you THAT busy ( no I did not say lazy ) ?

Just take the footswitch off the 2 kw linear amplifier, and use it, or make one from scratch using available parts and accessories.

How about a footswitch from an old sewing machine ?

How about a footswitch from an old car that had the HI/LOW headlight control on the left corner of the driver side floorboard ? Remember them ? Man you ARE old !!!I also remember them...so I am old, too.

Just some sarcasm and a couple of ideas for modifications for all those who read this .

GOOD LUCK

Now if you really need to switch a BIG load, try the footswitch GM used to crank the starter on a '53 Chevy Pickup!

Heel on the gas peddle, toe on the starter switch; crank the one-lung six-popper while you give it a little gas.

That switch had a pair of really big contacts since the starter in a 6V system drew beaucoup current.

How's THAT for old? http://www.qrz.com/iB_html/non-cgi/emoticons/biggrin.gif

I still have one. I'm... older than the car it's in anyhow. http://www.qrz.com/iB_html/non-cgi/emoticons/tounge.gif

Or just buy one. You can get the Heil foot switch for about $35 new, and it's *expensive*.

I've been thinking about taking my D-104 apart. Still works fine, but the PTT doesn't have the "spring" it once had. Maybe I'll leave it alone...

My parents traded in their car with a button start for one with a foot start. I got my "cheeks" reddened when my sisters explained why the car wasn't parked exactly as dad had parked it.

I would sit in the driver's seat, repeatedly touching the starting pedal. Without the key in the ignition, it would not start. But it would jump! I think it was a '49 Chevy.

Now I have to ask, why did you take the mic apart to hook up a foot switch? One would just connect the switch to the PTT circuit of the radio. It would be rather awkward to have the mic wire to the rig, and a wire from the foot switch down on the floor to the mic . . .

I don't see any need for opening up a D-104 to add a foot switch. Just wire the footswitch in parallel with the microphone connector push to talk connections.

Better yet, make a "Y" connector with one side going to the foot switch, on side going to the D-104, and the third side going to the equipment.

This is what I have basically been doing for well over 40 years.

That's what I did with my boom mic (not a Heil OR a D-104, though the footswitch is a Heil). Works great and I love the "zero desk space" solution.

'48 GMC pickup. Taught myself to drive, and run a stick at the same time.

Took my dad a while to figure out why the tank didn't last too long, but nothing came of it.

The street was a downhill, so I'd crank the wheel over, put it 2nd and bump the starter. Turn the key on half way down the block, shift to 3rd, let the clutch up, and gone ;)

Tangent, I know, but I do miss that truck..

[K9STH]

The company that my father worked for (and eventually bought) had a 1947 Chevrolet pickup truck that I got the "pleasure" of driving in 1961.

The clutch and brake pedals were like 1/2 inch high by 3 inches long. Also, they were spaced fairly close. That truck was definitely "fun" to drive (note that the "fun" is in quotation marks).

Glen, K9STH

[KD7WHQ]

I suppose it was a getting used to, Glen ;)

That was for all intents and purposes the same truck.

I had a lot of fun driving it, and the guy down the street is going to get asked about that '54 in the yard as soon as I become solvent again ;)

When I was still fighting fire in the mid 80s, we had two engines with starter buttons. #One even had two--dash or foot.

But, then most of the older engines had basically two of everything--2 plugs per cylinder, 2 distributors, 2 magnetoes and an extra water jacket around the block to circulate hydrant water if something happened to single water pump. #It would take water from the fire pump, circulate it around the block and dump it into the street. #Only had to use it once in 11 years, but it was a motor saver!

Not much wiring in a microphone -- just a PTT switch, a pair of wires to the cartridge . . . . .

I'd just connect the microphone direct, and parallel a footswitch across the PTT lead to ground. Pretty simple, I'd say . . . .

Ya need to read my Nov. '93 QST article, "Solder to Talk." It solves all the problems. http://www.qrz.com/iB_html/non-cgi/emoticons/smile.gif
