Microham microkeyer 2 connection cable

Hi, I want to make a cable for microham microkeyer 2 for my flex 6500 for CW DVK Any users have experience about?

Reg

I had a Microham MicroKeyer II that I used with an ICOM IC-7800.  I sold the keyer with the IC-7800 because it was so well integrated and I hoped I wouldn't need it with the FLEX-6700 that I ordered.  I used the Microham DB37-IC-8 cable that was manufactured by Microham.  The Microham MicroKeyer II is a very complex and very powerful piece of equipment.  It is certainly possible to fabricate your own cable but with so many inputs and outputs it is not a trivial undertaking.  Microham makes a DB37-FX-5000 cable for use with the FLEX-5000A.  Before the FLEX-6700 was shipping I contacted Microham to see if the DB37-FX-5000 cable would work with both the FLEX-5000 and FLEX-6700, which was not yet shipping.  It seemed that Microham had invested the effort into designing a lot of DB37 cables and they would not share details.  I sold the MicroKeyer II with my IC-7800 on the hopes that I wouldn't need it with the FLEX-6700.  That certainly turned out to be the case.  The Microham MicroKeyer II is a powerful and well engineered piece of hardware but it is not necessary with the FLEX-6000 series radios.

Have you contacted Microham to see if they have a cable now for the FLEX-6000 radios?

Good luck with wiring the DB37 connector.

Tried Micro Ham,  Micro Keyer II  on Flex 6500 and KX3 last week . Wiring went easy (WO2X) 

Also added my Signal Link USB to work into the back of the Flex 6500 No Problem.

However  Yes However the DAX works sooooo!!!!  good I found no need to use either.

Tnx per la risposta, mi  MicroHam for CWX and DVK, I hope as soon possible FRS implements CWX and DVK 


MicroHam not Support FlexRadio, I write on Yahoo Group and a MH reply me no SUPPORT

Frank:

Check out the post in this thread from Ed Baker.  He built a cable so his Micro Ham Micro Keyer II would work with his FLEX-6500.  If you ask Ed for his wiring details I'm sure that Ed, unlike Micro Ham, would share his FLEX wiring details with you.

Thanks Reg's suggestion, I hope Ed can report a link where to find directions for the construction of a cable Pearl 6000 series, I possess a cable for icom and do not want to destroy it to make one for flex, I tried to connect the MIC via a adapter that I created to change the links to icom mic to flex but I have an echo in my modulation, so I can not use the DVK microHAM.

However, I did a study of the cables, and I have identified that a cable for YAESU FT847 could do to our case, in fact the connector pin to 8-pin microphone is identical to the FlexRadio 6x000 also I have seen that uses the RS-232 protocol thus linking the DB-9 connector to the computer and suitably configured DD-UTIL I think it can also transmit the signal CAT FLEX, what do you think? you could try having a cable ready

Ok on wiring. At my qth Dave wo2x wired the interphase harness from the micro ham to the rear 15 pin on the rear apron of the flex I Have contacted wo2x and asked him to directly contact you on wiring. I am away from my qth and do not have the documentation but I am presently enjoying my boat in warm weather. Forced to use my ic7000 on digi modes Ed np2g

Ed baker

Dave wo2x will contact you this evening. Hopefully he will post it also on this format. Ed

Hi Frank,

Sorry for delay. Been busy this past week. I was using a DigiKeyer II with the 6500 which uses a DB 15 connector, not the DB-37 connector. I did download the manual for the MicroKeyer II.

Attached are the pinouts from the DB-37 connector to the Flex DB-15HD connector.

David Decoons, wo2x

I noticed the attachment does not show up to other users.

here is the pinout

Signal                     DB-37 (Micorham)         DB-15 (Flex)

Line In (TX)               18                                   1

Line Out 1 (RX)         19                                   2

CW/FSK Key             28                                   4

Ground                      15                                   5

PTT In                       27                                  14

Please note - The Flex does not support FSK keying in on pin 4 at this time.
