If you haven't caught on as yet -- there is a ton of homebrew projects being developed from VK/ZL land. Want proof of that statement, just visit VK3YE's You Tube Channel.
A site worth visiting is from ZL2PD. There are many projects on his site which range from test gear to complete radios.
The above is an example from his website. This sure lets you see what is going on between the rig and the antenna. Bravo.
I also suggest getting a membership with the G-QRP Club and receive the quarterly SPRAT publication which is chock full of useful radios/test gear. A hallmark of this publication is that what is presented is typically not complex nor requires a home loan to undertake. Issue 200 is soon to be in the mailboxes.
The ubiquitous and often cursed LM386 Audio Amp has been put under the microscope by LA3ZA. If you have ever done the homebrew mating dance, then most likely you have touched a LM386!
The internet is a vast resource to peek into shacks the world over and have a look see of what is on the bench. For many US homebrewer hams, regrettably they limited themselves to the work of W7ZOI, W1FB and W1ICP. (Hayward, DeMaw and McCoy). Certainly, these were tall pillars but there are many more homebrew resources now in the world.
We only need look with wide eyes to see the amazing stuff coming from Farhan and Hans Summers. But many highly talented homebrewers are unknown but yet have done significant work to enrich our shacks and give us new toys on the bench.
If you are a US blog reader and are not registered to vote but eligible to do so -- git er done!
