Re: Delta 44 Interface module question
- I've been reading this thread and I thought I would jummp in and ask if any of you may be able to help me with a problem that is driving up a wall. It relates to a problem I posted a couple of weeks ago. I'm using HDSDR software and a Soundblaster X-Fi Surround 5.1 Pro as the sound card with my my Ensemble TX/RX. I'm trying to use VAC as the interface between HDSDR and Fldigi for digital comms, but have only got it to work a couple times out of about a hundred tries. I have finally been able to determine that whenever I have VAC connected to HDSDR output, the input from the sound card is distorted. When I disconnect VAC from HDSDR and use a hard-wire solution with the onboard sound card for an interface with Fldigi, I have no problems copying the various digital modes. I was able to verify the distortion with VAC connected to HDSDR using the record feature. Recorded signals with VAC connected to HDSDR and vice versa.
I'm using a Dell E6420 laptop with Windows 7. Any thoughts on what might be the problem. I've played with all the VAC setting, but no joy. I'm thinking for whatever reason, VAC is interferring with the transfer of data from the sound card. I'm not a computer guru, so it could easily be some setting that is not correct.

- Thanks, for the report. I was not sure if I could use this sound
card. I had other sound cards in sight but when I asked here they
said it would not work. Now I know that this sound card will work
fine. I will search for the sound card mod to see how much of an
effort it will be before I go ahead and buy this sound card. I am
sure I will be able to handle it but just in case it will be a good
idea for me to check.
Can you send me pictures of your setup showing your cable connections
to antenna and computer and any other devices in your setup? You can
send them to my email address. If others can send me pictures of
thier setup, this will be great. I want to see how people
interconnect their units and external devices to the softrock (if
