Joe,
There are no issues with bias on either mic connection. The operator can select bias to be on or off for both the FP and RP mics. 73 Greg AB7R -----Original Message----- From: [hidden email] [mailto:[hidden email]]On Behalf Of Joe Subich, W4TV Sent: Wednesday, December 05, 2007 7:39 PM To: 'Rick Tavan N6XI' Cc: 'Elecraft Reflector' Subject: RE: [Elecraft] microHAM K3 cables ...

I was under the impression that the K3 was wired the same as Kenwoods for
microphone usage. However, In checking the Heil website, and the subsequent link for mike connections, they show that pin 5 is 8 V., whereas the K3 manual shows that pin 6 should have 8 V. Actually the website for Heil doesn't really show how the various adapters (I.E. for the Heil Traveler) are wired. It only links you to the website of G4WPW for a description of various pinouts for various rigs. What's the deal? Also, the K3 manual specifies a low impedence mike (600 ohms +/-). Nothing on the Heil website that I have found actually discusses what the impedence is for mikes like the Heil Traveler or Pro Set. I'm also curious why my Heil Pro Set headphones seem to have low output compared to other headphones on various rigs that I own. Anybody know what the impedence is for the headphones?

Dave,
The pinout is the same. You can take a hand mic from a TS-870, 570 whatever and plug it into the K3 and it works fine. For electret mics, the K3 is capable of supplying bias on both the front and rear mic connections. For mics that are high impedance there's also a switchable level of gain for both mic connections. I use the proset and they work just fine. I also use a PR40 and that also works fine. The proceedure is to use the MIC SEL menu to choose the desired mic and use the "1" button to toggle the gain between hi and lo and the "2" button to toggle the bias. 73 Greg AB7R -----Original Message----- From: [hidden email] [mailto:[hidden email]]On Behalf Of Dave Yarnes Sent: Wednesday, December 05, 2007 7:51 PM To: Joe Subich, W4TV; [hidden email]; [hidden email] Subject: Re: [Elecraft] microHAM K3 cables ...

Joe,
The Elecraft K3 manual shows pin 6 as 8 volts. This is *not* necessarily the mic element bias. The bias would be applied directly to pin 1 regardless of the use of pin 6. Remember that the addition of bias to the mic AF line is a function of the menu setting rather than an added resistor as in the K2. The voltage at pin 6 will not be turned off when the microphone bias is turned off in the menu. For use with the Elecraft MH2, MD2, and Proset K2, the requirement is for a voltage to be added (through a resistor) to the AF signal line. That same configuration *should* work for all electret mics that are similarly wired and do not have a capacitor in series with the AF line. Yes, the Elecraft mic pinout is different than Kenwood because Kenwood uses pin 5 for +8 volts and Elecraft uses pin 6. A Kenwood dynamic microphone having no preamplifier in the mic head will normally work just fine with the Elecraft pinout - but user be aware - you should know the pinout of any microphone you plan to connect. A Heil dynamic mic (usually HC4 or HC5 element) with a Kenwood adapter will work fine because neither pin 5 nor pin 6 are connected in the adapter. 73, Don W3FPR Joe Subich, W4TV wrote: >> I was under the impression that the K3 was wired the same as >> Kenwoods for microphone usage.

Greg, > There are no issues with bias on either mic connection. That's may be the case if one is using an Elecraft microphone (or a computer headset in the rear panel). However, if one has a Heil or Kenwood electret wired to Kenwood's specification it will not work. The Heil/Kenwood will have a capacitor in series with pin 1 (Mic +) and a resistor to pin 5 (bias). The cap will block the Elecraft bias on pin 1 and fail to connect to +5/+8 on pin 6. 73, ...

OK, I just found the cable circuit on the microHam US site (why isn't that
on the UK site?) - now I'm even more confused (you know that ain't hard to do) For the microHam spec ( http://www.microham-usa.com/Products/USB/Cables/DB15-EL-K3.pdf), the K3 cable uses all the rear panel connectors I'd expect it to. So what is this talk of the front panel connector about? Got to discuss something while I'm waiting for my K3 ....

Joe,
That is why I internally 'bristle' a bit when I hear folks say that the Elecraft microphone is the same as Kenwood. Even Bob Heil had made that statement to me when I specifically addresses it with him last year at Dayton. Perhaps he really meant that the pinout was the same with respect to *his* microphones, or perhaps he had never checked about the pin 5, pin 6 swap. Remember that 'compatible' does not necessarily mean 'equivalent'. 73, Don W3FPR Joe Subich, W4TV wrote: > Argh! Another case of being "almost the same."

Well, what it tells me (I think) is that I had better get busy and make up a
conversion cable, swapping pins 5 and 6, if I want to use any Kenwood microphones. I guess I'm curious as to why Elecraft felt it necessary to make this pin swap. In the K2 we could simply wire that rig any way we wanted. So why not go with a more standard pinout for the K3? I guess I'll have to ask the gurus in Aptos that question. Truth is, I probably know the answer. By the way, Heil doesn't even show an adapter cable for Elecraft stuff. Maybe that's because the K2 could be wired internally multiple ways. But now that the K3 has established a hard-wired standard, possibly they will. It's just too bad we can't have more standardization in things. But we see this kind of thing all the time. For example, Icom has their own unique type connectors for separation cables, etc. Translated, this means "not easily reproduced". Sony is one of the worst--try using after market stuff on their products--even their power connectors are relatively unique. Don't even get me started on power connectors with all the differing inside and outside dimensions! Sure, some situations dictate using smaller or larger, but generally it seems we could get by very well with just 3 or 4 sizes instead of having 15 or 20! So, my next question is, how are the microphones sold by Elecraft wired? I don't see any real disclosure about the actual pinouts on the website. I assume they are wired exactly to match the rig, which means I might not be able to use one of those with my Kenwood. Making my own adapter isn't that big a deal, just a pain in the butt.

Dave,
Such is the situation with most all amateur equipment. I figure it got started when the manufacturers started making additions to the features on the microphones. The old 4 pin microphone connector is largely a thing of the past - but it was easy - 1 pin for AF, another for AF Ground, one for PTT and the 4th for PTT ground - there were versions that used only one common ground pin and used the remaining pin for a voltage (some Ten-Tec transceivers for instance). Once microphones were equipped with more than a PTT button, more pins were needed, and each manufacturer made up their own pinout - and the microphones became unique to the rigs produced by that manufacturer. The result is that we have the chaos that is with us today. An easy solution is to just bite the bullet and buy an Elecraft microphone, or buy a Heil with a Kenwood adapter. Bob Heil explained to me that his microphones (except for those with an electret element (such as those for the Icom - iC suffix) had only 4 pins - AF, AF Ground, PTT and PTT Ground - his adapters routed his 'standard' 4 pin arrangement to the proper pins of the transceiver. The Heil Kenwood adapters do not use either pins 5 or 6, so there is no conflict between the Elecraft pinout and the Kenwood for *his* adapters. 73, Don W3FPR Dave Yarnes wrote: > Well, what it tells me (I think) is that I had better get busy and > make up a conversion cable, swapping pins 5 and 6, if I want to use > any Kenwood microphones. > > I guess I'm curious as to why Elecraft felt it necessary to make this > pin swap.

The latest Heil ProSets come with miniature phone plugs -- a stereo one for the phones and a mono one for the mic. These plug into the various adapters for the various transceivers. However, they also plug directly into the rear panel mic and phones connectors on the K3, so for this microphone you do *not* need to buy a Kenwood or other adapter. -- 73, Vic, K2VCO Fresno CA http://www.qsl.net/k2vco _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.
