Reviews Summary for MFJ-640 2 Radio Selector/Mixer
MFJ-640 2 Radio Selector/Mixer Reviews: 1 Average rating: 5.0/5 MSRP: $49.95
Description: 2-Radio Headphone Selector/Mixer

MFJ-640 combines or selects audio from two different receivers -- Great for operating "split" for HF contests and DXing, or cross-band for VHF/UHF satellite.

Just connect the audio output of two receivers to the two 3.5mm audio connectors
on back of the unit. Then plug in your stereo headphones and you are ready to go.

MFJ-640 provides both 1/4 and 3.5mm stereo headphone jacks -- no need for adapters!

From the front panel you can select the audio output desired - Mix, Radio 1,
Stereo, or Radio 2. In the Mix mode both radios are combined in both the left and right earphones, and the audio mixing levels between the two radios are controllable. In the Stereo mode, Radio 1 is heard in the left ear and Radio 2 is heard in the right ear.

Compact 4 3/4W x 2 1/8H x 5D inches.
Product is in production.

Simple, handy accessory  Time owned: 6 to 12 months
I use this unit to select or mix the receive audio from my K2 and K3 transceivers. By also using an antenna splitter with the receive antenna inputs of the two radios, I have dual-receive capability, with the audio either mixed or in stereo. The unit uses passive circuitry and requires no power.
