protection in rig if SWR is high

VK3SQ - Geoff #41449 Greetings all. If the SWR is high what does the 7000 do; eg does it shut down, reduce power what! Thanks for your replies. 73 de Geoff vk3sq
Michel MNR #41450 Il réduit sa puissance en HF. 73's de Michel? F6FSC Le mardi 3 ao?t 2021, 03:25:36 UTC+2, VK3SQ - Geoff <vk3sq@...> a écrit : Salutations à tous. Si le SWR est élevé, que fait le 7000?? par exemple est-ce qu'il s'éteint, réduit la puissance quoi?! Merci pour vos réponses. 73 de Geoff vk3sq
Joe Krout All Messages By This Member #41451 By design, it is supposed to reduce output power, however... My experience has been that at high power levels, it will blow the driver transistor.? To help avoid an expensive repair,? reduce power to 10 watts or less for initial tuning, and monitor your SWR as you slowly increase power. I also find using a good external auto-tuner with the correct interface cable is wise.? I use an LDG IT-100 tuner. 73 Joe KR0UT?
Don Rolph All Messages By This Member #41452 My understanding?is: - if it is running SSB on HF, then SWR is fed to ALC and audio, and hence output, throttled back to protect the front ends. This protection is not?available?on AM,CW, or FM. toggle quoted message Show quoted text On Mon, Aug 2, 2021 at 9:25 PM VK3SQ - Geoff <vk3sq@...> wrote: Greetings all.
