Tuning for maximum noise or ‘S’ meter is the easy way to go but;
Usually if you connect your antenna and see some rise in the spectrum noise then you are about there..
If you want to go to FULL antenna tune for receive then look around for a small, very helpful device known as miniVNA or anything along this line..
They run for about $50 and will present you with an LCD screen illustrating a Smith chart that indicates your antenna measurement to exact Resistance and Reactance values.. Say 50 ohms @ resonance you will see a DOT which is the Bull’s eye center of the target, like throwing darts..
If this becomes interesting enough for you to try then you might even download a free program called SimSmith, very interesting..
