There is no difference between the empty antenna port and the one which is the antenna is connected to. I've tested the other bands but the rest are OK. 10m antenna line is OK on R2 (FT857D). Is that possible that only the 10m goes off? What can be the reason? Thanks and 73!

(whew) luckily no issue with my good old 1000MP. ;-) Thanks and sorry for the bandwidth. 73!

I have noticed that my FT1000MP RF output starts out a bit low and rises as I transmit on FT-8. I have it setup to transmit 25 watts with the remember power settings set on the WSJT software. Well the next day when starting to transmit the RF output is close to 20/22 watts, and as I transmit the output rises to a bit over 25 watts with me not touching any of the previous day's settings. If I crank the transmit audio power slider up on the WSJT software to push it up to 25 watts, then I wind up having to pull it back down just a tad to keep it at 25 watts. I also have to bump the audio level slider up a few db on 10meters. It seems like I'm getting increasing gain somewhere as the transmit section warms up. Any idea what I have going on, or if something bad is fixing to happen to my radio? Thanks all. 73!

It is also sensitive to where in the passband you're transmitting - the power at the edges lower than in the middle. Unless someone has an example which says it's a precursor to a problem, I've ignored it as one of the rig's design "features" (others being the fan doesn't always cycle off and the birdies every 80 khz or so). 73, George VE3YV / K8HI -----Original Message----- From: 1000mp-bounces at mailman.qth.net [mailto:1000mp-bounces at mailman.qth.net] On Behalf Of J Bowen Sent: August 17, 2020 23:46 To: 1000mp at mailman.qth.net Subject: [1000mp] Question about FT1000MP RF output rising during FT-8 So everyone, I have a question.

On the "200 watt" rig I run 50 watts of a digital signal and have not seen the output power change significantly as radio gets warm and fan comes on. What you are seeing is probably not a problem.
