The FT817 loses 3 dB
At first my signal was heard, later everyone agreed that Bert was not heard.
When Rob PA1X mentioned that there was something wrong, I started to check, but it was already too late.
Due to the serious mismatch, the FT-817 delivers less power.
At first I thought that the PA of the FT-817 was deceased.
But later, on the dummy load, on HF the Rig showed a sign of live.
The maximum power is now 2.5 W and the lowest power is abt 300 mW.
I can still use the FT-817 with reduced power. In many contest QSO I use the lowest possible power. I can still make 50 mW using 0.5 W and an attenuator of 10 dB.
I will miss the position for a power of 980 mW, as being the highest power for QRPp
Over the last months I encouraged other Bloggers, to use less power than 5 watts, to make a 1000 Miles per Watt QSO, when the distance is less than 5000 miles.
The maximum power of 2.5 W from the FT-817 will still give 1000 MPW to Canada and the USA.
But I will miss the extra punch of 5 watts, that I only use if necesarry.
