Performance Issue with piHPSDR version 1.2.3
Posted: Wed Feb 14, 2018 5:06 am
Greeting to all!
I have a piHPSDR control head in use with an Anan 7000DLE.
Using the controller with factory issued SW version 1.0.7 the unit operated flawlessly.
I recently updated to version 1.2.3 piHPSDR sw.
I really like the expanded feature set (dual VFOs & advanced noise reduction), but lately I have noticed platform jitter with the waterfall becoming “jerky” and transitory audio artifacts heard during RX. The issues seem to arise after several minutes of RX time.
The LINUX CPU performance monitor shows about 37% usage while the performance degradation is occurring.
The SW upgrade followed John’s advice to rename/delete the original piHPSDR folder to avoid GPIO pin assignment issues.
Has anyone else encountered similar performance degradation?
I could always reinstall ver. 1.0.7, but that seems a bit atavistic.
I am guessing this may be due to system clock error between the raspberrypi cpu and Orion II cpu.
Using:
piHPSDR VER. 1.2.3 built 2017-12-28
S. No PiHPSDR0058
WDSP ver. 1.16
Directly connected by CAT6 LAN cable to:
Anan 7000DLE
S. No 7000DLE0030
Orion II protocol 1 firmware version 2.1
Any insight to this performance glitch would be much appreciated.
