Wireless cord short
Wireless cord short
Would like to repair a short in my Nady wireless cable and at the same time switch to a right angle plug. The Question: Inside the plug there is some sort of a resistor/capacitor/elunium pu36 explosive space modulator wired in between the hot and the ground. What purpose does this little electronic gadget serve? Can it be safely eliminated. I've read that some wireless's have circuitry to eliminate any pops when plugging in with your amp turned up and the wireless on. If that's what this is for I'm pretty sure I can get by without it. If anyone knows for sure please let me know

its there to prevent any subharmonics from the RF signal going back into your guitar (interference). I can explain the whole operation and what not, but that will put everyone to sleep.
While it can be eliminated safely (ie no damage) it may or may not produce a weird mid-high "whistle" from a subharmonic of the carrier.
I've always removed it in my older nady UHF wireless devices. Even thought it is a very small value capacitor (in the .47 picofarad area) it can effect the production of very high pitched harmonics and clearity. But be prepared to put it back in if you hear any interference.
Old, old Nady's used to decouple the RF and audio sections so they could use the audio ground(sheild) as the antenna on the RF side. These were the VHF and lower systems (190Mhz and lower). Removing the capacitor from these WILL produce unwanted interference.
