REPORTS from USERS of SGC Smartuner:
OE1MHA: The tuner is not tuning every length of wire, but just very specific random wire lengths seem to work well. Especially 23m long wire seems to work very well on all HF bands.
OE3JKS: could not tune my wire at all! Possibly it was mounted too low? ( just 2 meters above ground)
OE5MZC: Tuner hangs as soon as I try to match on 50 Mhz. After this it does not retune on HF. No action at all. Reset or Power-Off necessary to cure the problem. But all other bands work well with the Smartuner in the middle of my multiband dipole ( instead of a balun ) Also the cover is not waterproof! The screws often come loose and they are difficult to refit, since they are hidden in the rear aluminium panel.
OE1PYA: used SGC-237 with a 10m high fibreglass fishing rod vertical ,close to the car. Antenna wire run through the plastic bumper of car and tuner was safely inside the trunk, tuning well on all HF bands.
OE3XMU: 25m long helically wound wire around 10m long fibreglass tower on top of 7m aluminium mast with 15m long counterpoise on the ground performed very well on HF bands. ( worked 28 ITU-zones during one night ) but also problems on 6 meter !?
