[Elecraft] K2 audio output for digital modes

Mon Dec 8 13:38:01 2003

Hello K2rs,

As promised on my yesterday's message, I have uploaded a PDF file with the title "K2DI_K2DI-PCI" containing some
provisional info on my PCBs.

Because of the pictures it is a rather long file, more than 600 K, so please DO NOT OPEN IT ON LINE but download
it by right clicking on the link. You'll find it in my website:

http://www.qsl.net/ea3blq/

Point to Menu -> click on Downloads and right click on the "NEW" marked download option "K2 DIGITAL INTERFACE v.III
plus K2DI-PCI COMPUTER INTERFACE".

Look forward to reading your comments, if any.

Thanks for your interest in my project and Season's Greetings.

: Hi Wim and all K2rs,
:
: I have just developed a couple of PCB, one motherboard, the K2DI-III (the same circuit as the K2DI v II.2, but
: smaller) and one daugtherboard, the K2DI-PCI, to interface the former PCB direct to the computer's soundcard and
: serial port, featuring either
: RS232 or TONE PTT (user's choice) and isolation from the computer by means of an optocoupler and a couple of two
: 600:600 transformers. Ideal for backpackers.
:
: Currently, and unlike the K2DI v.II.2, these boards can be installed in the K2 (not the non split K2/100) and
they
: may coexist with the KAF2 or the KDSP2 as well as with the internal battery.  Ideal for backpackers.
:
: Have tested the prototype boards and they work fine. Hope that I'll be able to make the finished (and as usual,
: silk-screened and double sided with plated through holes) PCBs available to K2rs by Christmas.
:
: In the meanwhile, please allow me up to 24 hours to upload some info (schematics diagrams, drawings and pictures)
: to my website www.qsl.net/ea3blq/ . I believe I have some good news for the non split K2/100 users too.
:
: As soon as I upload this info I'll post its availability in this list.
:
: Thanks for bearing with me and all the best.
:
: 73 for now.
