No bashing of Apple hardware. Thanks. I've also posted this on Apple's Community Forum, so I added some additional amateur radio info for them... ---- I have an AirPort Time Capsule 802.11ac ME177LL/A (2 TB). It's in relative close proximity to my Yaesu FT-991 amateur radio. My radio has been sitting in this position for almost 2 months with 2 antenna wires (one for VHF/UHF and one for HF) running underneath my desk. And I've been transmitting on the 20m band (14MHz) for 2 months fine. No problems. Until a few days ago when every time I transmitted on the voice part of the band (14.225 MHz to 14.350 MHz for General licensees) my AirPort Time Capsule powers off (transmitting voice by hitting the push to talk [PTT] button on the microphone). It takes unplugging it from the rear and re-inserting the power cord back into for it to power back on. I've been able to repeat this on different frequencies in that range (14.225 MHz to 14.350 MHz). I can transmit fine on every other band and the digital, CW (morse code), and RTTY portions of the 20m band (14.025 MHz to 14.150 MHz) with the radio connected to my iMac with a A/B USB cable. (Physically, it's not the ideal setup, but living in a townhouse I'm somewhat limited with space, inside and out.) Like I said, I've had no issues transmitting in the frequency range for 2 months. Nothing has changed. Wiring hasn't changed. Location of anything hasn't changed. The amount of power hasn't changed. No equipment for my radio or computer stuff has changed. Any ideas??? Thanks. ------ FIRST RESPONSE from someone: It is a pretty unique problem. Hard to imagine the wireless is actually directly interfering in any way.. although the physical distance to much higher power wireless can do strange stuff. I am more incline to think it is the power supply in the TC which are known to be fragile. Can you plug it into a power point far away and run it on extension cord, or even just move it away for a test.. Even if you have no internet connection.. What sort of internet do you have btw?? Does the main modem have any issues when you are transmitting? Remember a lot of stuff is happening in cable at freq not that far away from your 14mhz band. ----- MY RESPONSE: Comcast cable with my own modem (Motorola SurfBoard SB6121). The modem is about 3 years old. I did move the Time Capsule about further away (3 feet), but my radio still knocks it offline. Any further will take a few days so I can get longer ethernet cables. I'd need two cables (from the cable modem to the Time Capsule and from the Time Capsule to my iMac). Although moving it 10-20 feet into the middle of the townhouse & into the hallway isn't an ideal location for the Time Capsule.
