Yesterday, I tried my 4m QRP transverter on TX with the FT817ND. It said "HI SWR" on the FT817ND. Not sure what was going on, but it is probably something simple, like a dry joint.
I was very pleased with the results yesterday on 4m FT8 RX with just the 40 MHz antenna.
If the fault really is trivial, I am undecided about the erection of a 4m halo. Such an antenna would give me access to 4m.
Roger,
ReplyDeleteThe "HI SWR" you got from the FT817ND when using your transverter could this be down to there being no 5v on your FT-817ND connector and maybe you modified your orginial FT817 to provide 5v on the either BNC or SO-239 antenna?? Looking at you circuit diagram you marked RF + 5v ??
Just a thought?

Yes, you could well be right!!
