id egde coil

[rbholt80]

Could some one measure with and ohm meter the rx and tx coil resistance and post it for me. I dont have an edge but i do have an id-excel and was wanting to mod a bigger coil to work but if the id-edge coils have the same specs as the id-excel then i would buy one and use it for the excel. I just need to know the resistance of the coil windings on the id-edge to see how far off they are from the id-excel.

thanks

Maybe you could use one of these?

Well I dont have an inductance meter to test the mH of my coil. I was just going by resistance as its a good way to test a coil for general purpose. But thanks that did help some cause I do have a Cz6a. But I still need the resistance reading from an id-edge coil. I guess Ill have to buy one and test it to see if it will work.

Now that will be handy till i order another inductance meter. I dont know what happend to mine. I have all the formulas from my college classes but i didnt think to find inductance that way. Sometimes the simple things just pass us by like duh lol. Hey thanks

Im going to use a protected supply voltage with current limiting just to be safe. I would hate to burn up a coil. time to break out my old function generator and O scope

A small transformer that can only supply a few 100 mw would be safe on most coils.

Voltage is what its based on.

With a small transformer, you can use a POT to get it set up.

You don't need a Decade Box.

I have a 1 meg ten turn pot. I dont have a step down tran. thats why i was going to just use my function generator but now i have to repair that. It seems that it sat so long that some caps dried out and are causing a bunch of noise. One even shorted when i turned it on. I replaced it but the others are needing replaced. I may just junk out an ac to dc adapter and get the transformer out of it.

Down Load this program and you have some of what you need!

Now that is cool. I knew a sound card could work as a scope but I didnt know someone had mad a software package for that purpose. I suppose a very good sound card would have a better resolution verses a 16 pit card. But I guess for low Hz apps a 16 or 24 bit a to d converter would work just fine. So My card will work for what i need. Yay lol all digital scope right on my computer. Now i just need the time to do all this testing.

Thanks for that link I will download asap.

Only foos for audio low end. Still Cool though!
