Subject: DXbase Interface Problem Survey

I am posting this for K5ESW who has not arranged Internet access
since retiring from IBM. I have the same problem with DXBase and
have tried four different serial cards to try to accommodate the
flaky serial port routines provided with DXBase 3.0 for HF radio
control. I have purchased a buffered 16550 type serial card in
desparation , hoping it will be the "workaround" needed. This
problem exists in at least DXBase versions 2, 3 and 4. I have
NO other programs that have any serial port problems with my
hardware configuration (which is standard). My Hardware: 486dx2
(33 MHz), COM1 / COM2 / LPT1 used with standard addresses and IRQ,
200 MB IDE Hard Drive and VGA video card; HF Radio Kenwood TS950SD
with IF232 interface box.

 IF YOU CHOOSE TO RESPOND TO THIS SURVEY, PLEASE DESCRIBE YOUR
 HARDWARE (INCLUDING HF RIG INTERFACE) EVEN IF YOU DON'T HAVE
 THIS PROBLEM.

K5ESW's DXBase SURVEY / Problem Description follows.

****************************************************************

From: K5ESW  Date:  6-Nov 1453Z  Subj: DXbase & HF Rig Problem Survey

I use DXbase 3.0 and have been happy with it except for one problem.
When I first start DXbase I often get a message "Unable to link to
radio".

After this message the only way to get DXbase to talk to the HF rig
interface is to go to the QSO LOG menu, choose USER SETUP, choose
USER PROGRAM OPTIONS, and then hit Escape. This causes DXbase to
reinitialize communications with the HF rig. I usually have to
repeat the entire sequence several times before the rig interface
is successfully established. If I do not notice the "Unable to Link
to radio" message I sometimes log a QSO on the wrong band because
DXbase will use the last band logged if the HF radio link is down.

I called Dean, W8ZF, and asked him about the problem. He said this
was uncommon and suggested it might be due to an interrupt conflict.
I have looked my system over and cannot find an interrupt problem.
My hope was Dean would tell me they had improved the error recovery
in DXbase 4.0, but he said there have been no changes in this area.
I would like DXbase to retry initialization with the HF rig after an
error. This would save me from going thru the awkward manual method
mentioned above.

You can reproduce the above failure my simply leaving the radio off
at the time you start DXbase. The user's manual says that my situation
is expected but rare. Page 104 says,"4. Timing was out of sync at the
instant initialization was attempted. This situation is classified as
normal, but it should rarely happen." My failure is certainly not
rare.

Are any other users experiencing this failure? Send me your comments
and I will post a summary message.

Also how many of you are using DXbase but DO NOT use HF rig control
at all ? Maybe the DXbase developers think the problem is rare because
most of the users don't use the HF radio control features and
therefore never experience the problem.

I checked with the developer of Logic4 to see how they handle the radio
interface. He said they do not try to remain in sync with the HF rig.
They initialize the interface every time Logic4 needs to communicate
with the HF rig. I ordered a demo disk to try it out.

My particular setup here is an ICOM 765 with the rig interface on COM3
using IRQ 5 (normally reserved for LPT2). My TNC is a PK-232 connected
to COM2 using IRQ 3. I have a data/fax modem on COM1 using IRQ 4. I
run Windows 3.1 and use DXbase in a DOS window.

Hi Michael, we have a different exam site each weekend here in San Diego.
You can call 619-465-exam for a recording on where the site is located.
However, they usually like 10 days advance notice. It can get crowded,
and some sites do not take walkins. The SANDARC VE prg gives there exams
on Sat mornings, and the SANDARC group does not charge!! That is where
the proceeds go from our convention that is held here about every 4
years. If I can be of any further help, please let me know.

Earlier this year I passed the five written and one of the code tests,
as well as taking the other two code tests which I didn't pass, all in
one session and the total time was two and a half hours.  That's
including the time for the VE's to grade my exams, along with all the
exams of the other candidates, as well as waiting for all the forms to
be filled out and signed.

Four months later, I passed 1c to get my Extra. :-)

I have done test with the IC481H, the 430 MHz version. I found it to
be totally unacceptable for 9600bd :
- tx-rx turnaround times are more than 100ms
- tx is a VCO modulated PLL transmitter. There is a big peak in the
  modulation response around 41 Hz.
However, receiving was ok. So i guess our tests are'nt compatible..

I went down.  I busted a hole in the floor of my radio room (concrete slab)
that corresponds with 3 runs of 4" PVC - 2 heading for the tower, one back
into the basement.  I sealed it up with concrete, and sucked a 'mouse' thru
the pipes with a shop vac.  Works like a champ!   Before I got the outside
hole completely sealed I had 2 Carolina Wrens visit my radio room after
having eaten everything in sight!  (They left the residue everywhere).

For apartment or other installations where you can't/don't want to drill
through walls or windows, you can make a simple feedthrough using two
pieces of lumber, which you then close the window on, keeping
drafts out.  Sandwidth the two pieces of lumber together with C
clamps, and then drill holes of the appropriate diameters for the
cables you need to pass through, with the holes centered at the junction
of the two pieces of wood.  Sample:

      |                     |
      |   SLIDING WINDOW    |
      |_____________________|
      |_______/\_____/\_____|  <- top piece of wood
      |_______\/_____\/_____|  <- bottom piece of wood

(The diamond-shape holes are supposed to be circles, but as we all know,
programmer's shouldn't attempt to do art.)

Drill more holes than you need initially to save labor later, and plug
the unused holes with pieces of rag or dowels or corks from wine
bottles.  As you need to add/remove cables, you lift up the window,
take off the top piece of wood, and lay down the new cable, and
reassemble.  Doing it this way instead of drilling holes in
a single piece of wood allows you to get cables in/out while
the connectors are attached.

If you pick two pieces of wood that are narrow enough, the window will
still shut enough so that you probably won't have to do anything special
to keep drafts from coming in where the top half and the bottom half
of the window meet (where the latch is).

For drilling, the dimensions of the common sizes of cables are listed below:

RG-58 size - .195"  (use 13/64" or 7/32" bit)
RG-8X/RG-59 - .242" (use 1/4" or 9/32"  bit)
RG8 - .405" (use 13/32" or 7/16" bit)

(The smaller of the two bit sizes listed above should make a tight fit to keep
the cables from pulling in/out).

I have one.  I've converted it to 10 mW output for driving transverters,
which I build myself.  I've almost bought the Chipswitch uProc, but I'm
using my IC-726 as a 50 MHz XVTR Driver, so the Uniden gathers dust.

Anybody have the Chipswitch uProc in yours?  How do you like it?
