Added 4 new radials to the 40m 1/4 gp.
Freq SWR Before SWR after
7.0 MHz 1.05:1 1.70:1
7.1 MHz 1.05:1 1.30:1
7.2 MHz 1.10:1 1.10:1
7.3 MHz 1.30:1 1.00:1
Adding the radials appears to have shifted the best match up about 300 KHz . Not a big deal because the radio tunes it out flat across the band with the full power output.
Lesson learned .... always start with 8 Radials then tune the GP!
Also found the vertical element wrapped around the tree that supports it and missing a bit of its counter weight definelty anything but vertical. Changed the counter weight and unwrapped it from the tree ...all good now!
First QSO with the radials added was EI3KG in Ireland he was a 549 and he gave me a 559....pretty cool eh!
