Today I also tried scanning for the first time. Most of the time RX stays put and doesn't scan.
Wouldn't it be a good idea to use squelch as a variable threshold for the time being and find a smarter auto-threshhold later? The only good HF squelches I worked with are "syllabic" squelch/scan systems (Very well implemented on maritime Sailor equipment!) Not fast but very accurate without "false" hits. Sailor can scan on 6dB s/n signals which worked great for DX openings. Their syllabic system works with a "frequency to voltage converter", quoted in manual: SQUELCH The squelch is voice activated, which is realized by detecting whether there is a change in the mean frequency at the AF-filter output. The squelch circuit, which contains limiting amplifier, frequency to voltage converter, voltage change detector, and hold circuit, generates a signal by which the microproc- essor controls the squelch switch U07 at the receiver output. 73' Paul PD0PSB Hi Jan, The scan function sets its own threshold automatically. I have plans to improve this further. But meanwhile, you can turn the preamp off or the attenuator on (or narrow down the bandwidth) to change the threshold. 73, Wayne N6KR -- View this message in context: http://n2.nabble.com/Adjust-the-level-when-the-muting-starts-when-scanning--tp2961133p3039267.html Sent from the [K3] mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
