QRM on 40m

We have lot of QRM of illegal stations in Asia and pacific on 40m band.
This morning we had a QRM who was speaking Malaysia so it was difficult to copy EU stations.
I try again QRV on 40m tomorrow morning.

Possible to QRV from 40m to 10m

Still FT-991 has a lack of TX power.
80m band is driving maxim 1.0 watt as QRP.......
40m band is 30 watt.
However from 40m to 10m getting around 500 watt helping by SPE Expert 1.3k-FA.
Unfortunately I can not QRV this season on 160m and 80m.

Before this FT-991 had same problem of lack power and repaired by Yaesu service, Moreover you can found same problem of FT-991 on Blogs. I don't recommend to use FT-991 on your important DX- pedition, losing pile up. 
I not sure but maybe FT-991A would be improved it.

FT-991 has a problem

FT-991 does not work well with TX power down,
on 40m 30 watt, 20m 80 watt.
However fortunately SPE Expert 1.3-FA work with small driving power to gain rated power.

Next week I'm taking a summer vacation in JA visiting to Japan Ham fair held on September 2-4 by JARL which normally used to be on the last weekend of August.

I'm not sure but the Official saying, changed the date of the Ham fair due to a preparation for 2020 Tokyo Olympic Game at same place.

The day of Ham fair also All Asian DX Contest PH is held too by JARL.......Who will be on the air ????

However Don't worry, Japanese contesters are choosing to participant in AA contest.
