Hello all
I would like to know does the markIII have a ping just with a d-104 mic or it should have it with also the 776mic or banana mic??
I know that the cap needs to be in place and correct one. wondering if the mic used matter..I only have used a d-104

No, the microphone doesn't matter. But having the squelch turned up will.

Also the value of the cap will make it longer or shorter.

The frequency response of microphone, crystal compared to a dynamic, will have a slight effect on the quality ( higher or lower pitch) of the ping.
I always liked the sound of a D-104 element.

I use a D104 G stand, bananna mike, and a Turner 454X on my Brownings and notice no difference in the ping. I'm not a fan of using a power mic, that may change the ping but I've only had experience on Browning models up to the Mark III. The modulation on those models is so strong that you don't need a power mic. I'm not very familiar with the 4's and 4A's but I know that they came with the 776 wich is powered either by battery or voltage from the radio itself. I do know that there are a couple of versions of the 776 but I don't know enough about them to go into that. Browning on!

Ya, I've never noticed a difference in the ping because of the type of microphone, either.
On the Mark IV and IVA transmitters, they provided 5 volts to the 776 microphone. Not a bad idea as you never had to replace any battery on the base of the mic.
I've used a Turner +2 on my Mark III, but I prefer using the EV 'banana' instead. The +2 works well too. As you said, you really don't have to provide much extra audio drive for that radio. Any un-amplified microphone would work well with it.

Plenty of audio gain. |

Back to the Mark III ping. Maybe the value of the ping cap still isn't large enough in value. Try a 47 MFD capacitor, you still might have to go with a little larger value to get the ping that you want but don't go much more than you have to. That will make the ping so long that it's irritating and that is also hard on the transmitter relays.

My 'Ping' just turned into more of a low tone pong!
I use the brown stripe 776 on my MKIII but now it has a pong with the 776.
I can run a D 104 and the Ping comes back, please don't tell me my 776 is passing.

I can run a D 104 and the Ping comes back, please don't tell me my 776 is passing. The "ping" is really a momentary acoustic feedback from the receiver. The pitch of the ping has a lot to do with the frequency response of the microphone. Since the 776 has a flatter frequency response than a D-104 (which is pooched at 2 Khz), the pitch of the ping will likely be lower. You can try orienting the mic a little, as that can also affect the pitch of the ping. |

It's just that it just up and started doing that. I thought something may be going south like a tube or cap. It is a everyday driver, no parking here.
I use the squelch most of the time local.
Thanks for the reply sandbagger...

Thanks for the reply sandbagger... Turning up the squelch will subdue or mute the ping depending on how high you set it. But try re-orienting the mic and see what happens. |

Try another 12AX7 in the receiver.

Moving the mic around did nothing so I pulled the cover on the receiver.
After replacing V9 the 12AX7 tube with a known good one the Ping came back.
Thanks Fixr, Sandbagger for the help...
