Mic Gain Adjustment

[email protected]
 

Does anyone have a suggestion for adjusting mic gain on the FT-60? I need to increase it to use a Heil HTHY headset.
?
 

Have you messed with the TX deviation setting? That Heil setup has worked for me for many years.

Hi Clint,

Does the FT60 supply DC bias for the microphone element or is there a battery holder in the headset?

Thanks Gary. It doesn't have a bettery, but someone else suggested adjusting the TX deviation. I'll look into that.

You shouldn't have to adjust the deviation.?

Are you sure the plug is FULLY seated in the jack?

The Heil headset works fine here with both my FT-60 and FT-70.

Make sure the plug is firmly seated in the jack and the mic element is close to your mouth.

?

Also, the two ends of that tiny barrel-shaped mic capsule are 180 degrees out of phase, to help cut down on background noise. Meaning, if you talk into the side of the barrel, between the two elements, you will sound thin and quiet.

NEITHER.

Icom is the brand usually supplying voltage to an electret element.

As I said in my other reply, make sure you are talking into eather end of the capsule, not the side, and have it about an inch from your mouth, if not closer. Make sure the plug is firmly seated. I haven’t had a single problem with several HTH headsets for yaesu and Kenwood HT’s here.

Well an electret microphone element must have DC bias to function.?

Maybe the Yaesu version of this headset uses a dynamic element?? I tried but failed to find an owners manual on the Heil website.

On the product page at the Heil site, I see four links:

?

DESCRIPTION

DYNAMIC

IC

SPECS

?

Given that Dynamic and IC are separate items, I figure there is a difference that goes beyond the connector type.
 

I have followed this process with success to improve transmit audio. ?https://youtu.be/R3Ovv5_TVNg?si=ZYNq_RZvCvk_aoT0

Well...Heil's website is awful.? I don't think "Dynamic" refers to the microphone element type.? When you click on it it takes you to a review page.

If you click on "specs" it says...

Let's simplify this. If purchased new from an authorized Heil and Yaesu dealer,?
that Heil mini-boom single-sided headset work great. There is no widespread?
problem with that combination of items.
?
SO ... if the Heil isn't working well, the chance that it is defective is slim. A
possibility - but slim.
?
A common error on our part is messing with the TX Deviation of the FT-60R.?

As Clint points out, you may have the Deviation set to "Narrow" +/-2.5KHz instead of the default "Wide" +/-5KHz. See manual page 62.

The other possibility is the FT-60R Mic socket itself.
It is notorious for "spitting out" speaker/mic connectors. Elastic bands are one solution as mentioned elsewhere. That is what I currently use:-)
I also had many hours of hair-tearing frustration trying to get Chirp to connect via an after market programming lead.

The problem is the inside diameter of the recess at the connector is too small for the majority of (industry standard?) connector shells.
This results in the plug not fully seating, resulting in the connector contacts actually pushing the plug out instead of locking it in.

In my case with the programming lead, I carefully filled the moulded plastic body down to fit into the recess. That all works now.

In the case of the Heil mic, it could be that the connector body is fouling on the recess, preventing proper insertion of the plug.
Measure the mic plug body and the recess with a pair of vernier calipers to see if it will actually fit correctly.

A more universal fix would be to make up a Forstner type drill bit to ease out the connector recess in the FT-60R to the bigger "industry standard" diameter.
The difference is subtle, probably something like 6mm versus 1/4". Sorry, my calipers are in the shed, it is late at night here and it is bucketing down with rain.
