Re: [Flexradio] Common Mode Chokes - Purchasing Ferrite

This solution looks much easier and cleaner than applying ferrites to all the cables. Are these isolators effective? Is there anyone on the list actually using these? Paul Delaney - K6HR -Original Message- From: flexradio-boun...@flex-radio.biz [mailto:flexradio-boun...@flex-radio.biz]

Re: [Flexradio] Help! All of a sudden no audio and no waveform in the panadapter

Michael Closing PowerSDR and power cycling the radio usually cures this. Windows likes to forget about the flex driver at times while PowerSDR is not running. I usually shut the radio off count to ten and restart the radio and wait to hear the windows notification sounds then start PowerSDR. If

Does the driver see your radio? Also, make sure its not in demo mode (it happens when you don't have your radio connected and you accidently press Yes in the dialog box. After that, it doesn't even look for the radio, it stays in demo mode! 73 Neal Campbell Abroham Neal Software www.abrohamneals

Re: [Flexradio] Common Mode Chokes - Purchasing Ferrite

It is important. The effectiveness of the impedance provided by the ferrite is determined by how close the material is to the electromagnetic field (the common mode currents) that is magnetizing the ferrite material. I suspect that the inverse square law would be applicable in this case, so tw

Not everyone can use a mouse with the same precision; consider those with poorer eyesight or rheumatism in their hands. Tracking someone on a satellite for (say) 60 seconds while they drift in frequency (CW or SSB modes) would be much easier with a knob than a mouse - at least it would for me. I

Since the Flex 5000a cw goes thru a computer there will always be a delay. For me this makes the Flex internal cw keyer unusable. Many here will tell you they can get the delay to a minimum, but for me ANY delay makes it impossible to send good code. I use a Logikey K-5 external keyer. I use t

I don't believe that to be 100% correct, but knob tuning is a personal preference. I operate a IC-910H and with the software I use to correct for Doppler shifts, I never touch the tuning knob. It is all done with a mouse, which is a lot more comfortable in my hand ergonomically that a horizont

Re: [Flexradio] RFI WEAKNESS --move on

I see the advantage of the IC-9100 being the tuning dial. Many Hams on linear transponders do not use Doppler correctly so it's often necessary to continually tune to their transmission. This is a problem with all SDR unless there's a nice, comfortable knob available. It's also a challenge for SDR
