    Reviewing & testing the Heil PR40, PR781 & PR77 Microphones.

    Some great dynamic microphones available through Heil Sound. Bob, K9EID offered me the chance to test these out after a frustrating experience I had with a condenser mic!

    Big thank you to Bob, K9EID, & Heil Sound!

    Also another big thank you to my almost 500 subscribers - how cool?! - thank you so much!

    Johnny, I like the review you did. I had an email exchange with Bob a little over a year ago about what you just covered. I went with Bob's recommendation of a PR781. I have the the same Behringer Q802USB mixer and JBL speaker you used in the video. I use it on my IC-7100 for my HF, Skywarn NCS and what I need to do for identifications for running Newsline, ARRL Audio News and The Rain Report. Based on audio reports from operators in Denton Co. they love the audio I get from my 781. The PR40 is great but I have been told overkill for HF. I did have to install isolation transformers between my IC-7100 otherwise the audio had a significant amount of hiss. Bob and George have both mentioned this on HamNation, gotta love ground loops but the installation of the isolation transformers was trivial.

    Good job on the review.

    Johnny, the audio from the 77 sounded better when you switched it to music. Are you sure that you didn't have it backwards on the switch setting?
    Watch that part of the video yourself.

    Great and useful demo of these microphones! I have the less expensive Heil HM-12 and would love to have that model included in your demo as it is much less expensive than the ones in your video. I would think may hams would be interested in that comparison.

    Are Heil the only mic's out there worthy of reviews?

    I've got a Heil PR28 and with Bob Heil's help I got it hooked up to my FT857D. I've gotten nothing but great sound report and I love the quality. You may pay a little for Heil mics, but let me tell you -- they are worth every penny.

    If you were using the clip-on mic in the beginning it was far superior to any of the desk mics. As soon as you went with the Heil mics there was a lot of background hiss that wasn't there before. In the on air demo with hdsdr the audio was definitely way, way over compressed.

    Until I put in the isolation transformers in the paths to and from my IC-7100 I also had the hiss. The ground loop was killing the audio. Both Bob and George talk about the need for 600 ohm isolation transformers on their shows.

    There are but you really can't beat the support Bob and his staff provide.

    I found a mic review that was broadcast industry aimed from Kirk Harnack in the side bar after watching Johnny's review. Multiple sources including the PR-40.

    You can tell big differences in the audio. I suggest steering clear of sub $100 mics.
