[wsjt-devel] WSPR frequency on 80 meters
I might have missed it somewhere but all my newer wsjtx builds now have 3.5726 as the wspr frequency. It was and (still being used) 3.5926 I do not know when it was changed.

Re: [wsjt-devel] Compiling issues...
You need libusb-1.0.0 and the -devel package I suspect. Had a similar issue with this on my old centos 6 box and had to compile that from source..

[wsjt-devel] PSKReporter displayed freq for FT8
I noticed that pskreporter is displaying the exact RX freq for jt65/9 signals but not for FT8. Is this by design? It seems to be displaying the frequency that is configured in the settings->frequencies for that mode in WSJT-X. Was just curious. Using r currently.

[wsjt-devel] Linux JTSDK build problem.
Hello, Can someone contact me perhaps directly if needed to answer a couple of questions? I had JTSDK 2.0.21 installed on ubuntu 14.04 and it was working but would not update the devel wsjtx to current, so I removed it and re-installed. I have built hamlib, when I try to build the latest devel of wsjtx it complains it cant find hamlib. I am sure I must have missed something in the re-install. It has no problems building the other programs i.e wspr, just not wsjtx.

Re: [wsjt-devel] Center rx frequency question.
Bill, Thanks for replying. Sounds like you are pretty much saying the same thing I already do. I have one instance using my soundcard connected to my Kenwood, the other instance uses my rtl_sdr dongle with an audio stream from rtl_fm. If I create two audio streams (no matter what the source) I can simply run two instances of the current wsjtx. I am trying to envision a method of using one stream that contains multiple channels? However what you said made me think. I am no expert on sdr / gnu radio only having a dongle for a couple of months. It *may* be possible for me to re-sample the I/Q data from rtl_sdr into multiple usb demodulated streams. I was hoping there was a simpler way of perhaps shifting the *tuned* frequency in wsjtx. This could even let me monitor other modes within the sample I/Q passband range. Thanks again. I will plod along with this idea and see if I can make it work. I can always get more dongles.
