Slows down, then freezes
|
Group- IC-7300 & Win-11 PC. FLRIG is controlling the 7300 & FLDIGI. 25 watts, or lower output. Single USB connection between 7300 & PC. I start an Olivia CQ, and part way into the CQ the waterfall slows down then freezes and the PTT stays on, although no RF is going out. My audio levels are OK on test tone and all modes.?? My IC-7300 is set the way I want - for FLDIGI, JS8 and other modes. Can someone suggest FLRIG and FLDIGI settings to try? Thanks & 73 Jay W6CJ |

Yes- not RF related. 73 Jay On Mon, Sep 16, 2024 at 3:29?PM Mike Black via <mdblack98=yahoo.com_at_groups.io_lastradioman@...> wrote: Does it behave if you lower power all the way down? |

Using HP wireless mouse. Thanks Jay W6CJ On Mon, Sep 16, 2024 at 9:19?PM Karl via <karlshumaker=yahoo.com_at_groups.io_lastradioman@...> wrote: |

I truly dont mean to sound argumentative, but I still consider this RF related until proven otherwise. Every time this has happened to me, RF was the culprit.?
?
My troubleshooting process involves ensuring all connections are solid, spacing system components further apart, moving antenna further away, adding more ferrites (wrapping coax and cables multiple times through appropriate ferrite mix toroids, not just clamp-ons), and decreasing power.? |

Group- Tnx for the responses.?? I'll be trying TRIPPLITE usb cables w/ferrite chokes at each end, removing the USB hub from the desktop and plugging in direct to the desktop, and a few more things................ 73 Jay W6CJ On Tue, Sep 17, 2024 at 4:44?AM Mike/N1JMC via <Clarkjmc=comcast.net_at_groups.io_lastradioman@...> wrote: |

Over a year ago when I was BEGGING for step-by-step instructions on fldigi, IC-7300 and RS-918 and suffering computer glitches it was recommended to get Tripplite cables, ferrites and all that to no avail. I got the Tripps, the ferrites and used them all with no change.
?
Every time I keyed the transmitter, fldigi would go nuts, lock up and I don't recall the symptoms. Others hollared "RF in the shack!" There was but not what they thought. The vertical antenna was 20 feet from the shack.
?
The ONLY thing was turning OFF the touch pad on the laptop AND using the wireless mouse.
?
Have you turned off your touch pad?

Thanks Karl, No touchpad with this HP desktop.? Mouse/keyboard are HP wireless. 73 Jay On Fri, Sep 20, 2024 at 2:57?PM Karl via <karlshumaker=yahoo.com_at_groups.io_lastradioman@...> wrote:

I have had fldigi slow and freeze many times. I don't use flrig. I don't recall if PTT stayed on. I was given all sorts of recommendations about RF, which might have been good advice. IMO, if RF were the culprit, I'd have seen the problems regularly. As an erstwhile software engineer and programmer, I thought (think) that in my cases, it is more likely fldigi getting busy with something that it doesn't plan for. For example, flmsg can hang if fldigi is closed first. When I see the slowing of the waterfall, I restart all fl_suite programs. In days past, if there were a comm stream problem, fldigi would hang. It's better now.
My experiences don't mean that RF can't be the culprit in any circumstance, just that it wasn't/isn't in my case. And in my case, the slowing/freezing of the waterfall is eliminated simply by restarting all fl_suite, and picking up where I left off. That's all pretty easy to do quickly, and, because I simply restart all comms and all is well, I have a hard time blaming RF. Sometimes I need to use the task manager to kill fl_suite. I can do that in seconds. I have my radios 0.25 m from my laptops. Well grounded system. No RF in the shack that I can see. I use various comm gear, such as direct control of the TS-480, and SignaLink and digirig. No problems on a regular basis. Powerwerx PS 0.5 m from all the gear. Tuners nearby. VHF/UHF/HF (480 & 830). 2 items I am curious about are USB traffic during this time, and %CPU used by any fl_suite program. ~R~ On 2024-09-20 20:34:, ve3ki wrote: Do you have any USB cables connected to the computer, regardless of what they are connected to? USB cables make great antennas for picking up RFI, and USB systems are vulnerable to RFI. I have personally experienced a case where RFI picked up by an unused USB cable (to a device that was not being used and was not configured in the software) caused other USB devices to crash (a soundcard and a Winkeyer connected to the same hub as the unused cable).73 Rich NE1EE The Dusty Key On the banks of the Piscataqua |
