No SSB RF output 6400M when using a laptop remote and usb headset
Art Wilcox
Member ✭✭
I am using a flex 6400M and trying to use SMART SDR on a windows 10 laptop connected wireless to my home network.
I just received a usb headset (MPOW) to use. I have the SMART SDR configuration on the laptop set to PC with DAX off. When I press MOX on the laptop, I see a normal audio modulation pulse on the pc screen ( when I talk) and also see the audio modulation pulse on the on the flex 6400M screen. I am not getting any transmitted ssb out of the flex 6400M via a power meter reading. I do get a reading when I use SSB the 6400m by itself. I have receive audio working fine on the remote laptop.
Any assistance would be greatly appreciated.
P.S. I am a new FLEX USER...….

Have you checked the transmit settings? Make sure you have PTT set to work. What mic are you using? i had similar actions happening and found a setting turned off , when set properly it worked fine0

I'm using a usb headset on my Windows 10 laptop. I click on mox and I get the audio signature on the bandscope on the laptop running smart sdr remote wireless connection on the same network. SSB mode 40m I see mox button light up on the front of my flex 6400M but no RF output on my power meter. If I run direct on the 6400M and the stock mic, I get RF out measurement on my external power Meter.0

You said you have DAX off. Are you referring to TX DAX or RX DAX. Make sure TX DAX is off otherwise your audio chain will not be enabled for the mic.0

Yes. Saving the settings/ profile once it is working correctly is very important.0

This is supposed to be a helpful forum not a critical one. If you need to vent, go to DMR where everyone is critical.0

The TX band width changes with the MIC selection, Make sure that the high and low frequency settings are OK for the PC MIC input. I had the TX band width change from 200-2700 Hz to 1700 -2100 Hz once( standard mic input), hence, no or very little RF out on SSB TX. That is indicated/changed on the "PHNE" control panel. I have no idea why it changed, the anomaly has not repeated.

Your video link pointed me to the issue. It was Blue = antenna 1 (receive) red=Antenna 2 (tx) on smart sdr on the laptop. Where I noticed something strange on the screen where RF power bar meter and swr bar meter were behaving strangely when modulation on SSB. Thing is I never touched TX antenna setting on the smart SDR . Time to save settings. Many thanks for all your input / help. Art KB1YAP.1

I’m new, looking for wisdom and leads about how to best start…and interested in tips for improved operatons and also cautions for frequent first mistakes. I never have found anything as useless and obscene as the negative braggadocio of this post, like who assigned this little boat man status as judge of the characters of FLEX owners. I looked at many of the posts hoping to find in all this bragging of knowledge and superior operations some seeds of helpfulness but instead have discovered where the guy in the Bible who sowed his seeds on bad thistle covered ground has gone…he isin this cheap laky boat lording it over strangers who soon will know much more than he obviously does. How ignorance can shout so loud is amazing. Intelligence is not loud!0
