OK, just to make sure we are seeing the same thing: with the latest CuSDR (version 3.2.14, 64 bit) and the latest Hermes fpga code (V2.5), I can set the sampling rate to 96 Khz and I can start 5 receivers. But the 5th receiver is non functional. I can't tune anything in that receiver. I can switch bands, etc. but it basically shows a flat response with a peak or two that look like spurs, but I can't tune any of the things that I can tune with the other 4 receivers.<br>
<br>
If no one else is seeing this behavior I'll go back to a previous version to verify that the problem (at least for me) is due to the fpga version and not due to something else I am missing.<br>
<br>
Thanks,<br>
<br>

Hi John,<br>
<br>
The 5th receiver is implemented in the latest version of Hermes (V2.5). It is used on Tx for pre-distortion but is still available on Rx.<br>
<br>
It tests OK using cuSDR at 96ksps - any faster floods the 100T Ethernet connection. I'll fix this when the Gigabit code is released.<br>

It appears the fifth receiver is no longer working with the new Hermes<br>
firmware. Did we lose a receiver as part of enabling the PureSignal<br>
feature, or am I doing something wrong? I used CuSDR to test with 96<br>
Khz sampling (since I believe that only 4 receivers were previously<br>
supported when using 384 Khz sampling). If we did lose a receiver is<br>
there any way of making this an option that can be turned on/off, or is<br>
there not enough room in the fpga for both?<br>
<br>
FYI, I run multi-channel WSPR reception with 5 receivers (sometimes 7<br>
with an old slightly buggy prototype fpga version that Alex once<br>
provided to me), so I like having as many receivers as possible!<br>
<br>
Thanks,<br>

I'm just sorting through my recent email; however, there are a few themes upon which I might be able to offer some useful comments.<br>
<br>
** 3.2.7 installs into a separate directory from previous releases. Also, 3.2.7 creates its database in a separate directory. So, you'll start with a fresh database and this release can readily coexist with previous releases.<br>
<br>
** As Helmut has pointed out, to learn more about PureSignal predistortion, open PowerSDR 3.2.7, click 'Linearity' on the menu bar at the top, then click 'Information' on the form that appears. Bill, KC9XG, has also provided some additional excellent documentation.<br>
<br>
** I see some reports of a front panel CW bug and other reports that it works OK. We'll need to check it out.<br>
