I have Spike version 3.0.21 and BB60A firmware 4.
I setup the frequency to 14.2 Mhz, span to 300 KHz, step to 100 Hz. I have an HF antenna connected to the SA and the ref level is set to -30 dBm. There is a USB signal at that frequency but is tuned off slightly. I access the audio player, set audio type to USB, BW to 3 KHz, (tried to set the low pass to 2.4 KHz and high pass to 800 Hz but won’t let me do it – instead it forces me to low pass at 3.0 kHz and high pass to 100 hz) and I hear the signal but is off frequency. (Deemphasis should not be needed in USB so not sure why the entry is active?) So I adjust the center frequency by stepping +20 Hz at a time and after about 4 steps the audio disappears. At this point I can no longer hear any audio. I switch to FM and there is audio. I switch to AM and there is audio. No more audio in USB, LSB or CW. I exit the audio player and then access the audio player again and still no audio. I save the configuration as preset 1. I then exit spike and then execute spike again. I load the preset. I see the signal and activate the audio player and there is audio. I then click on +20 Hz 4 times and then the audio disappears again. When I engage the audio player the sweep is set to idle so I cannot tune the frequency on the SA’s frequency control area. Any ideas why this is happening? The BB60A manual does not go into much detail for the audio player. FM seems to work ok on the 88 to 108 Mhz FM band.

If you are looking for more configurable audio playing, you might try out HDSDR (free software defined radio interface). On the downloads page,
look for the HDSDR compatibility files which will include a manual for setting up the software and the necessary files. HDSDR can interface our device and provide much more configurable audio outputs with real-time visualizations which might be useful for your task.

So what you are saying is that your audio player in Spike is known to not be working properly for USB, LSB, CW, and AM?
The reason I ask this is I want to be sure that the problem does not lie in the BB60A hardware!

Until I test your setup explicitly, I cannot say for sure, but it is very likely a software issue. Probably some combination of settings and actions caused the audio to stop working for you. I suggested HDSDR so you could continue to make your necessary measurements. Also, if you are doing lots of audio work, the HDSDR application offers much more functionality than our audio player.
