Re: [Elecraft] KX3 with KX3 Companion application
Aubrey, I think you are referring to the KX3 Companion for Android by Andrea IU4APC. I have tried this for lightweight operations.It woks by sending out commands to KX3 in ASCII over serial. Android<>OTG Adaptor<>Serial to USB<>KX3. If you want the waterfall to work - which us optional - I use the KX3 headphone output into the 3.5mm audio jack on my Tablet. This worked OK on my old Nexus 9. Some tablets don’t recognise the microphone input . The Android Headset Tester is a good bit of Freeware which you can use to check the microphone is recognised. Some tablets need an extra low resistance ( 1k3 ) to recognise a microphone is plugged in. PSK31 and Morse are sent as ASCII and the KX3 does the translating to the signals to modulate the SSB. I aren’t needed. I don’t use PSK31 any more but have moved to JS8Call and FT8 and hope we might get an internal KX3 or Android implementation.

Re: [Elecraft] OT: Speaker Wire Recommendations?
Are you certain that the RF is entering your audio system via the speaker wires? There are other possible points of entry that are more susceptible ... namely component interconnects, AC power wiring and other "low level" access points. RF chokes on all such cables may be necessary. That being said, it probably wouldn't hurt to replace the existing speaker wiring with well shielded, twisted pair. Just make sure to use a heavy enough wire (you say 'only 50 watts' but you don't specify the wire length), and to properly ground the shield. The one pitfall is that you will be adding capacitance to the speaker wires. Step 1 would seem to be exhaustive testing thru process of elimination. 73 Lyn, WØLEN -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Clay Autery Sent: Friday, January 10, 2020 2:10 AM To: Elecraft Reflector Subject: [Elecraft] OT: Speaker Wire Recommendations?

Re: [Elecraft] OT: Speaker Wire Recommendations?
I would get some mix 31 beads or cores large enough for several turns of whatever wire you choose at each end of the runs. Those long wires make for pretty good antennas.

[Elecraft] OT: Speaker Wire Recommendations?
OK... so I am knee deep in assembling and installing a subRX, et al., but got reminded by the XYL that I STILL have not addressed the signal bleed into the audio system via the long runs of parallel conductor speaker wires in the HT setup. In order to maintain a high "SAF" (Spouse Acceptance Factor), I need to deal with this issue WHILE I am in the attic re-configuring the network and routing various shack related wiring. I cannot imagine a stellar group of operators as are gathered here have not had to deal with this before. I am hoping that replacing the speaker wire with either simple twisted pair (or shielded, twisted pair, w/shield properly terminated) will mitigate the hits the HT system is taking. *Q: Do any of y'all have recommendations for a particular wire stock for use in this application?* Small system... only about 50W per channel on the 5 main speakers, so they don't have to be monster-sized conductors. I considered using CAT-5(+) wire and bonding all 4 pair to a single loop, but I don't think a single run would be enough copper (?), and I don't want to make multiple runs per driver. *Any ideas?* 73, -- __ Clay Autery, KY5G (318) 518-1389 __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
