Hello, Here is my story - Bought a 4 month old K3/10 off ebay (yes) from another radio operator in Texas. Unit arrived in excellent physical condition except that it won't transmit any audio using the MH2 hand mic.
The radio has - * K3/10 * KAT3 * 2.7 kHz 5 pole filter (standard) * 5ppm oscillator I have searched through the tubes and done the following - * Enabled mic bias * Enabled L./h. for front mic port * Adjusted mic gain / CMP / moni levels * Reset the unit to factory defaults and repeated the above * Upgraded the unit to latest firmware and repeated the above No amount of coaxing or loving is helping. The mic key-up works (TX lit) but no audio is transmitted. SWR / PO meters don't move at all. The radio "does transmit" when - * ATU cycle is kicked in * Rear mic port is used with a headset * CW paddle is used I sent a stinker to the ebay seller (awaiting response) but after hours of debugging, wanted to find out if this is just a dead MH2 hand-mic or could be an issue with the radio? Is there a way to test the MH2 electret element separately? The problem might just be between the MH2 and my chair and I am here to learn. Thanks in advance, -- VaibhaV Sharma W7VAI ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
