[W4FHU] Last call for anyone wanting a Digital mode kit.

As you might already know, our next meeting will be a construction meeting.
We will be building digital mode interfaces to allow your computer and radio
to operate on the  popular digital modes like SSTV, PSK-31, Packet, APRS, CW
and many, many more.   Even if you decide to not build a kit, you can help a
friend build theirs.  The meeting should be long enough to get a good start
on things but probably not enough time to complete a full kit. But I will
provide all the parts and instructions you should need.  Anyway, I need time
to order the parts to make sure I have everything people will need.  I
should have more then enough parts to build many more interfaces then the
club would need. But I also need to provide the radio connectors for anyone
wanting the complete kit.  Those connectors can be different for many
radios, so I need to know which radios so I can get the order in quickly.
While you might be able to buy the parts from a place like Radio Shack, the
connectors alone would cost more then the whole kit.  I order my parts from
out of country to get a good price. But I need to allow about 3 weeks for
shipping.  So, if you are interested in building a kit. Please let me know
by the end of this weekend. I'll be making the order for the needed parts on


I have attached a schematic of the Basic Interface we will be building.


Please look over the list below and see if your order looks correct.  At the
moment I can add or change your order to meet your needs, it might be
difficult later.
