|Customer Reviews for the MFJ-640.|
|From: steve k7awb|
|I bought it to solve a VHF contest problem. I use a IC-910 for 2 meters, 70 cm, and 1.2 gig. I use a IC-756proIII for 6 meters. I have two separate earphones, one on each. That means I have two sets of earphones on my head, not a comfortable position. This box allows me to work on 6 and listen on the other bands or vice versa with one set of earphones. Great!!|
The only problem I see is that the headphone jacks should have been in the front. It is a real pain to get behind the box and remove the headphones to use them somewhere else.

|I was hoping the two radios would be connected through isolation transformers for those cases where the two radio grounds are not at the same potential. As it turns out, they are not. No schematic was available online so I had to buy one to find out that I couldn't use it.|
Otherwise, it performs as adverised.
