Hi Skip,
No sir everything is stock. I have only used 40 and and 80meters.? Have not noticed much else wrong, If it is not broke, don't fix it. I have worked 40 states and Ontario with it and my bitx40. I use a homemade full sized 40meter dipole with traps and 48" extensions on 80 meters Using television 75? coax. Maybe if I had some commercial radio, I would see some areas that needed help.?
Still learning ditties so have not done anything with that yet.?
I am a newer ham and every project starts from scratch.?
