Has anyone used the UR6QW 8 Band EQ with the Flex 6000?
The EQ can be seen here: http://www.ebay.com/itm/8-Band-Sound-Equalizer-Echo-Compressor-to-YAESU-Radio-8-pin-mic-transceiver-...?
I have very little SSB experience but have been getting involved more and more lately. With a decent microphone and some setup assistance I've been fortunate to get some good reports or, just as good in my opinion, no comment about my audio.
I have the type of mid-deep voice that is though enough to hear on a telephone but the Flex's equalizer and other audio tweaking tools seems to take care of that issue on the air.
I use the W2IHY 8 band EQ and EQ Plus. I get unsolicited great reports with them but it doesn't mean you can't get very good audio reports straight into the radio. It all depends on what you are trying to accomplish. If running a dynamic studio mic straight into the radio such as the Heil PR40 you would be better served using a small preamp between the mic and radio.
I do not know how the UR6QW stacks up against the W2IHY gear.
One problem people do with EQ'ing in general is try to do very deep cuts in audio. Remember once you remove part of the audio (cut @ a certain frequency), you cannot add that part of the audio back in.
Sell whatever external EQ you have and invest in a better microphone as others have suggested, may I suggest a tube pre-amp, you will be amazed how the EQ in SmartSDR can make a microphone sound.
