Re: [Elecraft] K3s rear mic connector and shure SM58.

Electret mics, and capacitor and carbon mics, neither of which are real common in hamdom these days, require a bias voltage in the 5-8 V range.  A K3 will provide that bias if it's turned on in the MIC menus.  Dynamic mics do not require nor like bias.  Without bias, an electret mic will

The SM58 microphone does not need bias. 73, Don W3FPR On 10/6/2017 7:27 PM, Richard Day wrote: Why did you turn the mic bias off? Have you tried turning it on to see if it gives you the sound you need? Rich KK4DZE On Fri, Oct 6, 2017 at 12:27 Joe Subich, W4TV wrote: On

Re: [Elecraft] K3s rear mic connector and shure SM58.

Mic bias is used only with electret microphones. Dynamic (moving coil) microphones like the SM58 can be damaged by DC on the coil! The bias will certainly *further reduce* the output from the already low output of the dynamic mic. 73, ... Joe, W4TV On 10/6/2017 7:27 PM, Richard Day

It doesn't matter if the input is balanced or unbalanced. The shield and mic return should *never* be connected together. The shield is connected to the case of the microphone *not* a signal (mic -) line and connecting shield to mic - simply adds common mode noise and hum to the low level mic

No transformer needed.  The gain settings on page 55 of the manual are sufficient for the SM 58.   Just wire it as an unbalanced output.   I use both the rear or front MIC inputs with no issues and a variety of different mikes. 73 Bob, K4TAX On 10/4/2017 12:18 PM, Stewart wrote: OK

No preamp required.  Set the Mike gain via the menu to high. Easy to wire the mike XLR to an unbalanced circuit.   Pin #1 & #3 to ground and Pin #2 to MIC high.  See page 55  of the manual [MIC SEL] for details. If you close talk the mike it will be bottom end heavy. Typically no closer than

Re: [Elecraft] K3s rear mic connector and shure SM58.

OK here's what worked: I used a pre-amp, that was on hand, that has a balanced XLR input and a TS jack output. The SM58 does need quite a bit of gain to work but sounds good using the tx monitor. My SM58 has a switch so I set up to use VOX and the mic switch acts kind of like a PTT (only
