Hi Hermann -

Great to hear from you!

I tried the EME-2 on the EZ-Kit running with an old 486 PC and a second 
DSP-10 using the KK7P DSPx and a Pentium IBM laptop. The first was fine, 
the second hung and wouldn't come back!  Hermann,  what configuration are 
you running?  (My 486 does have a couple of minor differences, as I have 
been chasing the "E1" bug in it).

Also, anyone else that is using ver 3.17 of the PC  and 2.5 of the DSP, 
please try EME-2. What you can do is to set the RF Power to some low value 
like 50 (SCRL-O and -P) so that it does not send out power. If you have not 
used EME-2, it should transmit for 2 seconds, return to receive for 3 
seconds, update the display and then do it all over again every 5 seconds 
until you hit the HOME key again.  If it stops in transmit, you may have to 
reset the PC to get back going again. I did not need to reload the DSP---a 
sample of one!

Also, the "every-other-load" bug (of initializing the CODEC) is still there 
if you are running the DSPx.

I am not going to have much chance to look at any of these for the next few 
days, but I put the bugs in, so maybe I can get them out!!  Meanwhile any 
other data will be helpful, including the configuration.  Many thanks.

73, Bob
