Works for me, but...  Time owned: more than 12 months
A useful but limited device. It can connect to a maximum of two microphones. It can connect to a maximum of two radios.

IMPORTANT: Despite that fact that MFJ is still advertising this as "mix and match any two microphones to any two transceivers," you CANNOT interconnect two types of microphones and two types of receivers. You can connect two types of microphones to one type of radio (e.g., Icom and Yaesu mics to two Icom radios). Or you can connect one type of microphone to two types of radios (e.g., two Icom mics to an Icom radio and a Yaesu radio). It does NOT allow you to mix-and-match types (e.g., an Icom mic and a Yaesu mic to an Icom radio and a Yaesu radio). Got that?

The device is so lightweight that it will slide all over your desk if you just try to push the buttons with one finger. Either operate it with your thumb while you try to hold it in place with your fingers, or brace it somehow. My solution was to drill holes in the top and mount the whole thing to the underside of my riser.

The speaker on/off and volume controls only have ONE input. Unbelievably, they are not controlled via the radio selection button. For a device intended for two radios, that makes the speaker on/off and volume controls basically useless.

Excellent product!!  Time owned: more than 12 months
I've been using an MFJ-1263 and an MFJ-1260 (similar product) for YEARS without any problems at all! Simply put, they work well as advertised!!

Works for me!  Time owned: 0 to 3 months
Generally, I'm not a big fan of MFJ due to their ongoing problems with QC. However, I was looking for something that would allow me to switch a Heil Goldline (with an Icom cable) between my Pro-3 and my Kenwood TS-850SAT. I found a used MFJ-1263 at Universal Radio for $44.00 in like new condition with all the cables, etc. When I got the unit, I opened the case and checked all the connections for proper soldering, etc. and was pleasantly surprised to find everything in order. I set the jumpers according to the manual and the unit worked fine the first try. Other than having to adjust the mike gain down a bit it works as advertised and I had no problems understanding the manual.

Works For Me  Time owned: 6 to 12 months
I have 2 of these daisy chained and works fine. It was easy to set up but it took awhile to set all the jumpers.

I am using it to switch a PR-40/W2IHY 8 Band Equalizer and Noise Gate between 3 rigs. ICOM 756ProIII, ICOM 746Pro, Alinco DR-235

Great apart from instructions  Time owned: 0 to 3 months
The unit works so far as described but if you need to change a mic the instructions are not as intuitive as expected. The best way is to trace out the connection with a meter. A clue: leave the radio jumpers alone and connect using the mic jumpers, descriptions of this are not given in the manual

It does the job  Time owned: 0 to 3 months
I just got this. I was interested in something
that would allow for different mics to work
on different radios. What caught my attention
was the AUX input on the back along with MFJ
stating it could be used to connect to a computer
sound card output. It does do this however MFJ
did not consider a level adjustment control along
with a isolation transformer for audio hum.
What I had to do is remove the internal AUX jumper
for the audio and replace the jumper with a 100K
resistor. That took care of over driving the rigs
mic input.
On FM I do not hear any audio hum showing up
in my transmissions from which the transmit audio
source is my soundcard output. Have not tried
it on SSB. I was disappointed to find the AUX input only works on 1 of the 2 rigs.

A level adjustment for the AUX input along with
isolation transformer would have been a real plus.
I used the Headphone jack to feed the mic in on
my sound card. The headphone jack does have a level control.

RFI issues  Time owned: 6 to 12 months
No problem configuring this unit to mate up various rigs and microphones. Make sure you research and use the right jumper connections.

I notice some moderate RFI in the transmitted audio when using this unit on certain frequencies. A choke at the input has solved the problem. Also there is a bad connection in the PHONES jack (from the factory) which I have not bothered to fix since I don't use it. The usual QC troubles with MFJ.

Otherwise, it appears to function as advertised.

Works fine  Time owned: 6 to 12 months
I am using ICOM radios with ICOM Microphones. I found that the cables supplied were not wired "one-for-one" so I set the AR and BR jumpers as follows:

*set jumper horizontally on one row

Switch works fine now!!

You should be able to use any 2 microphones with any 2 radios with this just need to sit down with your radio manual and determint proper mike/jumper arrangements. It's a great idea!

Works with limitations  Time owned: 0 to 3 months
Purchased this to switch a Heil Goldline Pro and Heil Pro-Set Plus iC mic/headset between an Icom 746Pro and 706MkIIG. Works fine when switching the mics (both with 8-pin round adapters)into the 746Pro (8-pin round input), mainly because the internal jumpers are default set for Icom 8-pin round configurations! Trying to set the configuration from 8-pin round to 8-pin modular for the 706MkIIG is another story. Logic would tell you to simply match up the two radio's pin-out numbers, but I've tried everything I could and it doesn't work. There are separate jumper blocks for the common PTT switch and the manual is confusing in its description of configuring for different mics. Can't key up the 706. I have an inquiry pending with MFJ's project engineer on a solution. Also, they only have ONE speaker input to switch between speaker and headphones (with attenuating volume control). You'd think they would have TWO inputs to switch, since there's TWO radios involved, for maximum flexibility. What were they thinking?? of now it functions as their model 1260, which switches two mics between one radio! Other than that, no RFI (with 500 watts), build quality looks good. Will update this review when (and IF) I hear from their project engineer.
