Thanks A lot of precision handmade processes. My Blue Spark mic came in a big pretty wooden box too. The box had a nice aroma to it for several weeks.

I encounter a few hams using them who get too close or don't use a pop screen or sock and there's this distortion and plosive breath blasts in their audio. A lot of this would just go away if they used a good dynamic (which would sound FB) but they have an attraction to condensers for some reason.

Ribbon mics have the same vulnerability to poor mic technique, as do some dynamics like the Sennheiser 421. There's something called a "stage 'P'" that can help a lot once learned. Simply keeping the lips from sealing while forming the percussive sounds can minimize the plosive breath pops. That and the geometry between mic and the person speaking can keep the voice on-axis and the breath sounds moving away in a direction without impact.

We Ham guys close-mouth a condenture mic and we wonder why it is not what we expect.Ribbon mics have the same vulnerability to poor mic technique, as do some dynamics like the Sennheiser 421.

Watch a video clip when performers are in a studio. Those mics are far away from them. The only mic that tolerates closeness is the RE series mic. RE27........

The RE series supposedly is immune to it but you can also use it to your advantage if you have a good monitor and can hear your tx audio. I'd rather pay $400 less, get a SM58 and use any prox effect to my advantage. AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
