G¡¯day all,
I have been a reader and lurker in this group for a while and this is my debut post!
After a good few years of use and abuse my 817 has decided to give me a high VSWR reading on the 2m band.?
I have searched through the group posts for ideas and tried a few suggestions including a full reset to no avail.?
I have tried the rig on both front and rear antenna jacks and on 3 different antennas (all dual/tri band and all work fine on 70cm and 6m) with the same result.
It is not only indicating a high VSWR on the meter (occasionally displays text ¡°high VSWR¡±) but is folding back the tx power so I can¡¯t even trigger the local (60 over 9 normally) repeater.
When I did the reset I did disconnect all power and battery prior to the reset (home+power) as this was one of the suggestions I found.?
Does anyone have an insight into the problem?
Any quick fixes?
Any pointers on where to start trouble shooting? ?I had a quick read of the circuit description and have one area to check which is the 2 diodes off the directional coupler for 2M as it seems to be the only point that is not common to the other bands. Any thoughts?
I have not had time to rip the covers off yet so have not done any actual testing under the bonnet so to speak.
Oh and just to be clear it still receives as well as always on 2M on all antennas tested.
I am seeking the technical wisdom of the 817 hive to guide me
Cheers
