Car hobby takes a couple times my ham hobby money. Old Porsche.
But, as hams and the hobby has changed, the car is much more fun. Radio, less so.
For Hams, you can work the world with my setup on a small suburban lot.
An IC-7300, Powerwerx supply, 9:1 Unun (use BalunDesigns), a 33' pole (~$250 from Gigaparts), some copper coated antenna wire (Wireman) and a coax run (LMR) for an Inverted L antenna. $1600 - $1700 could do it if all new. Watch ads, you can save a few hundred used. If really on a budget, used K2, 7200, 450D all work. You can wind your own unun for $50 or less.
No doubt a young ham can find a elmer that has an old rig they could loan you. Old hams fading away, not a lot of young ones to replace them, unfortunately.
