Microphone Switch and Other Mic Questions

I have the RS60CF headset and the PR-781. Both have the XLR connector. I'd like to find a switch where I can switch between the two microphones without having to reach around the back of the radio.

I found this SoundTools - 3-Way Mic Switcher which will probably do the trick but I was hoping for a box or something to sit on my desk. Does anyone have an easily available alternative?

Reading some past posts I thought about buying a new cable for the Radiosport headset so I could use the Foster jack on the front of the 6500 but I use the M208 mic and looking at the RS site, the M208 is only recommended for the XLR. I sent Arlan Comms an email asking why as it isn't obvious to me. The M208 is the more ragchew-orientated microphone while the M207 or M350-ADJ is orientated towards DX. I wonder if anyone here might know why the M208 isn't recommended with the Foster connector.

And, if you don't mind me getting a little out of the Flex realm, I was going to buy another cable for the Radiosport to plug into my KX-3 but then a different mic altogether (M360) is recommended. Does the mic choice really make that much of a difference that I have to swap them out with different modern radios or cables?

Maybe a short XLR extension cable would let you bring the rear jack connection around to the front.
I have most of my PC's rear jacks using extension cables to make it faster/easier to get to them. Most XLR cables are extension type cables,  just buy or make a short one.

That 3-way switcher should get them all connecting in front of the rig.

You might also consider using a small mixer board with enough XLR inputs for all your mics instead of switching you can mix them all together, or solo whichever one you want active. The mixer would also provide things like a preamp, three way EQ adjustments, and phantom powering for condenser mics. I've used Behringer's MX802A mixer to mix both the mic inputs, and line outputs from my 6500. It does take up space on the desktop, but it has lot's of kewl knobs.

Or you could simply use a small Box with a DPDT Switch and 2 inputs and 1 output (to Radio)  1/4" Stereo type Phone sockets or XLR sockets what ever you use for the MIC's + and - and common Shields tied together.

Agreed, why pay more when you know how to solder. I had the mixer long before I had the need to mix mic's into my Flexradio. But right now I'm not even using the mixer. I've been using an ART TubeMP Studio V3, mic preamp which brings the XLR jack around to the front so it's easy to switch out a mic. But just extending the XLR connection around to the front is convenient enough, and might be all that's needed.  You don't really need a tube mic preamp, either. I just like buying toys!

This is what I use for my Electro-Voice RE27 and Yaesu M1. I am using the XLR from both. It also offers expansion for more Mics in the future. :)

Kev,

I use the RC60CF headset with my 6500 and have the M207, M208, and the M350-ADJ. I use all of them with the 8 Pin foster cable.   The M350-ADJ is a condenser mic, it can only be used with the 8 pin foster cable because it requires the BIAS voltage.   The M207 and M208 are dynamic so they do not require BIAS and can be used with the XLR cable.  

My best sounding XLR Mic is the Electro-Voice RE27.

Thanks Cal. This makes the solution easy. Buy a foster cable for the headset, continue to use the M208 and then use the rear XLR port for the PR-781.

Do you swap out the M207/M208/M350-ADJ for certain uses or have you settled on one for general use. I thought the M208 was a good choice because it has the wider frequency response compared with the M207 and I can use the Flex's audio tools to tailor it for DX or ragchew.

I mainly use the M207 during contests.  To my ears after several tests I found it hard to notice much difference between the M207/M208/M350 Adj.   For daily use I use the back XLR with the Electro Voice Mic.

Picked up Behringer MX802A and MX602A units for home and weekend QTHs respectively. Both were minty (one was NOS) at around $80 each.

Best XLR audio at home QTH has been with a Shure SM5B and for whatever reason the weekend setup best has been a Neumann BCM705 I'd picked up from another ham.

Experimenting with Behringer, Rane and Aphex outboard processing gear, as well as W2IHY ham specific gear has been with mixed results.
