HRD and Win7 T/R Switching Delay

[W4EG]

I had PDSR, HRD running JT65-HF. All was GREAT using Win 7/64 and previous verson of all software described in paragraph 2; in an old computer

However, here is the problem I have with a new computer that I purchased:

1. I bought a new i7 2600K (quad core) processor. Setup and working well with not issues.
a) Windows 7/64 Ultima b) 8 GB or RAM
c) All Antivirus, etc working.
d) All software have all the latest update and Service Packs etc...

2. Installed the following new software versions:
a) PDSR 2.3.5
b) HRD 5.11
c) VAC 4.11
d) VSPManager 103
e) Latest version of DDUtil
f) Using JT65-HF 1.09

3. CPU usage (Latency) is less than 8% (max), usually it's 4 to 6% with IE, Hotmail, Word, and everything that the computer needs.

All in paragraph 2 with the exception of 2.f works wel when I use it with HRD.

JT65-HF running by it self is fine. However, If I integrated JT65-HF with HRD, it starts on time. But, after the 48 seconds
of transmission, it has a 6 to 8 seconds T/R delay; which makes it useless for this mode. Since PDSR hangs on transmit and I have to manually force the radio off or go into the "Task Manager" and delete PDSR software.

I have check to see where the delay is coming from; but no luck.

Any suggestions were I may look; to see if I have missed or improperly set anything?

Or is this an HRD issue?

Thanks, Ernest - W4EG

I can't help you with your issue, just to let you know I deleted your other (Dupe) Post on the issue. No need to multi-post an issue, once is enuff.

I had this problem on my i7 990x machine, its a switching issue I fixed it by setting DM to fsk keying for everything except CW. Also you might want to try and increase the polling time as well as the buffer size.
