K2 and the UN-MODULE things

Hello,
I have a used K2 (2007 build) with KDSP2, KAT2, KNB2 and internal gel cell battery.
I have ordered the KSB2 SSB option as well as the 160m band/aux receive option.
If anyone remembers putting these options in, were there any lessons learned and so any recommendations you might be able to pass on to someone installing thesefor the first time ?
Thanks for any comments,
Doug

Hi Doug,

Take a look at the Rework Eliminator(TM) K2 Internal Mic Adaptor at
http://www.unpcbs.com/adaptor especially if you don't yet know what mic
you'll be using, or if you currently own more than one mic (with differing
pin-outs).

K2 and installing KSB2 & 160m

In reply to this post by Doug Hensley

Sorry for the bad subject line on my first message. I was going to ask about the UNPCBSthings and then decided not to. Here's my original question:

I have a used K2 (2007 build) with KDSP2, KAT2, KNB2 and internal gel cell battery.
I have ordered the KSB2 SSB option as well as the 160m band/aux receive option.

Re: K2 and installing KSB2 & 160m

Doug,

The best advice for installing options in the K2 is to simply follow the
instructions in order and work carefully. After you have installed the
same option 3 times or more, you might be able to take some liberties
with the instructions, but not the first time.

Re: K2 and installing KSB2 & 160m

In reply to this post by Doug Hensley

I just installed the KSB2 module by the book, and it worked no problem. One thing you may want to consider is the UNPCB microphone adapter kit, which lets you easily re-jumper the microphone socket on the K2 to make it compatible with different types of microphones without having to break down the whole radio. I didn't see a need for this flexibility in my particular case, so I didn't bother with that option, but if you may conceivably use the K2 with different microphones, it would be a nice feature.

If you don't get the mic adapter, and you use the Elecraft MH2 microphone, you can just jumper the standard headers directly across with the jumpers provided in the kit. If you want to use a different microphone, then there is a nice hack where you use a computer connector to make a jumpering block that lets you make connections without wire wrapping or damaging the microphone jumpering PCB headers on the control board.

Re: K2 and installing KSB2 & 160m

An added note - the jumpers that Matt is referring to are supplied with
the MH2 and the Elecraft Proset K2 microphones - they are NOT supplied
with the KSB2 kit.
You can use the 2 pin female 'computer' jumpers for mic configuration
header connections that connect straight across the header.

Examples:
-- for the Elecraft microphones, connect all pins straight across and
solder the 5.6k resistor between pins 1 and 6 on the back of the
microphone jack.
-- for Kenwood dynamic microphones put jumpers straight across all pins
except for mic pins 5 and 6 ( no resistor for dynamic mics)
-- for other microphones, refer to the KSB2 instructions.
-- If you have a Heil microphone (not the Elecraft variety) it will have
an adapter - wire the mic configuration header to correspond with the
adapter used (Kenwood, Yaesu, or Icom).

Re: K2 and installing KSB2 & 160m

Don's probably right -- I ordered the MH2 microphone together with the KSB2 kit, and I think the jumpers were indeed packaged with the microphone.

You can use the two-pin "computer" jumpers if you are just doing a direct 1:1 jumpering of the configuration header. If you are using a different type of microphone, here is the computer connector hack I was thinking of:

Re: K2 and installing KSB2 & 160m

In reply to this post by Doug Hensley

I used computer jumpers for the configuration header mic connector and they
work great. I also took a computer jumper, and used a Demel tool to cut a
computer jumper in two, then soldered a surface mounted 10 K resistor across
the terminals. The surface mounted resistor came from an old computer
board. This jumper goes to the 5V terminal on the mic configuration header.
I use this for the bias for a computer mic that requires 5V.
