Re: QSL cards
To echo others, a little ingenuity and some artwork from the internet goes a long way. Avery or other sources provide postcard-sized 4x4 paper sheets. Also, skillful use of the Avery 5160 labels allow

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

Another vote for eBay seller abcfab, though I note his prices have gone up significantly since my last order with him a few years ago. I guess the prices of many things have been going up over the

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.

Re: The end of inexpensive printed circuit boards and parts
