Re: VHF QRP project/building
Please pardon the delay in getting back to this post. It has been a busy week or so. I first wanted to say thanks for the ideas. In particular, Barb, that VHF module looks very promising for the task.

Re: QSL cards

Re: The end of inexpensive printed circuit boards and parts
I was about to say that this is another reason to adopt Manhattan construction, but Mike beat me to it. I have put in several orders with Mouser (my main trusted component source) in the last month.

Manhattan Noise Bridge
For some things that I test on a receiver, I find the following to be of great use around the lab.? It uses the fact that a zener diode will generate a lot of random noise.? Let's not nit the pink

Re: The end of inexpensive printed circuit boards and parts
If you need 3 PCBs, OSHPark special including USPS shipping is $10. But I don't see why they would keep this price when the competition goes away. 73, Mike AF7KR
