Rear Panel mic connection

I recall Eric mentioning an advantage to connecting the headset boom mic to the rear panel headphone and mic connectors. The manufacturer of the headset advised this was not preferable due to the potential for ground loops on the mic side. Has anyone had any experience with ground loops on the mic from headsets connected to the rear jacks? I'd love to use them to free up the front of the rig.

I don't even know whether the front connector works.

I have never heard of any such problem with using the rear panel mic and
phone jacks. A statement like that would make me wonder about the
construction and quality of the headset.
K9YC would say that there is a 'pin 1' problem with the rear jacks, but
that same 'pin 1 problem' exists on the front panel mic jack as well
because the jacks are grounded to the board but not to the enclosure.

The manufacturer is mistaken. We will contact them to correct this misconception.

Further on this - We have hundreds of users ( and possibly thousands) happily using the rear panel mic connector with the Heil Headsets. It is the preferred connection for many.

My K3 has a modified David Clark headset connected to the rear panel
jacks. So far, no reports of anything that would indicate a ground loop
problem.

This manufacturer is badly mistaken. There is no technical basis to his
advice. Many of us have used boom mic headsets like the Yamaha with the
rear panel connectors for years.

I've used the rear connector exclusively with no such problem ...
ever. I'm pretty sure I'm not the only one who uses the rear jacks. I
wish the front panel jack wasn't there and the space used for a couple
or three additional buttons for assignment of macros.

A really comfortable and great sounding headset.

The boom mike is the expensive part. As a plain headset,
HD280, it is 1/3 the cost. $83 at Amazon and I have seen
factory refurbished for under $50.

Used with a desk mike or on CW. The well known Yamaha
CM500 when I use a boom mike.

Re: Rear Panel mic connection

In reply to this post by Elecraft mailing list

I use both. For contests and DXpetitions, use a Heil pro set and foot switch with the mic in the back. For casual operating, prefer a desk mike into the front connector. Nice thing with the K3 is that it is just a menu selection to switch between the two. Elements seem to be a good match since I don't have to change gain / compression. Smooth with no issues noted.

advised this was not preferable due to the potential for ground loops on the mic
side. Has anyone had any experience with ground loops on the mic from headsets

I’ll speak up - I run my Heil Headset this way — it works great and no problems with any ground loops.
