I have been running a Heil PR 40 for almost a year and love it. I set the Transmit filter at 80 and 3080 to use the full 3000 cycles of SSB and then adjust with the equalizer to fit my voice, usually in a curve that looks somewhat like a smile. As a backup mic, I have a MLX 990 (requires a power source) I purchased online used for around $65. 9 out of 10 times it is hard to tell the difference in which mic is running. The Flex 5000 compensates for a lot of regular weaknesses in cheaper mics. I have three other Heil mics I have collected in the shack, the GM4, GM5, and the Gold Elite. When I put these on the Flex, I limit my ability. If I want get a sound like the DX Dream Machine of the HC-4 element in the GM4, I adjust the Flex settings and use the PR-40. Let me say first I love Heil mics, and the HC-4 element worked great for me on my FT920 hauling in the DX contacts. The HC-4 element concentrates on the frequency from 500 Hz to 3,800 Hz with a 10 dB rise at 2,000 Hz. If I set my Flex transmit filter at 500 Hz low and 3,500 Hz high and peak the equalizer at 2,000 Hz, I get a sharp, almost shrill high pitch voice very similar to the HC 4. I am sure Bob can explain that it might be similar but something is left out, but for me in a pile up it works great. I pull up the set up screen, change the low end to 350 or some higher number and give the call. As soon as they give me the call back, I punch in 80 to put the base back in and make a regular sounding contact. The MLX 990 will do the same, all because the power to make it sound great comes from the Flex 5000.
