What does the voltmeter on the rig’s display read, key up and key down? The point is to make sure there’s not an excessive voltage drop in the power supply connections or cable.

I have an Alinco supply set at 13.5v, it feeds right to radio. It doesn’t flinch when I key up. Doug On Jan 12, 2021, at 7:18 PM, Adrian Fewster <vk4tux@...> wrote:

No Push Operation on SELECT Control on FT-857
Radio works FB.? When I push the SELECT button, the? MHZ Freq should flash, then change Freq by rotating knob.
Press again, and KHz will Flash, change Freq by rotating Knob.
The Rotation of control does it's thing BUT pushing the knob does not function as it should
Dirty Switch?? Control is mounted on PC Board !? ?Anyone have this problem?
Where can you buy replacement Parts.
Tnx..Norm

Hi J.D. I may be interested in a nice FT857 depending on cost. I'll be taking my Tech and General exams in Feb. I can easily pass the online practice exams so I'm ready. I want something that I can take in the field while camping and operate on HF. I'm also considering the FT-817/FT-818 QRP rigs. Having the extra power of the 857 when needed might be nice though. I'm open to suggestions on the subject.
I'll most likely experiment with and build my own dipole's to start. Both as a learning experience and cost savings as I start off in this hobby. I already have a few portable power sources including controlled solar chargers. Living in New Mexico means lots of sunshine for solar projects.

Good thinking, congrats, I have that antenna, and I love it. Once you find the settings for each band, write them down, I call it my cheat sheet, makes tuning next time much easier.

Thx Leonard, nope that wasn’t it. Found it tonight - wasn’t the radio. My feed line was close to 60’ - this is too close to the quarter wave dipole I had up (130’) . I added 20’ to the ladder line and then it would tune.

Only having reflected power usually indicates they are reversed.
