Dear Bill:
ReplyDeleteAs you mentioned in the podcast, I agree that soldering all components on the top of the board with Manhattan pads is by far the preferable way to homebrew.
I recently bought and built a DIYRF TIA kit, and this re-enforced the fact that the through-hole method, while being compact, is extremely difficult to trouble-shoot and repair or modify.
Therefore I wish you would convince Todd to change to offering one-sided Manhattan-style printed circuit boards, with plain copper on the second side that can optionally be connected to the ground on the top.
Also, it would have been nice if you and Pete could have met in person for the first time (except for your joint April 1 business trip to Hollywood), maybe each driving halfway.
However, I have not left Central Florida in 6 years and now I only drive about 1500 miles a year, so I know how it is when you get old!
Thanks Walter. The campaign to keep our rigs "above board" has begun. As for Pete, I would love to meet him, but he is carrying some very heavy family responsibilities (with impressive grace) so this kind of meeting is impossible. But we have the podcast! 73 Bill
DeleteOne might add, the polarized relays don't have a diode in them - they are magnetically polarized. Only if the current flows in the right direction, the electromagnetic and permanent magnetic field add, excerting enough force to move the contacts. It's done to reduce the necessary current.
ReplyDeleteI didn't know that. Thanks. 73
DeleteYou have no idea how bad I hate kits, all of them need modded, and I destroy through hole PCBs left and right, it is totally aggravating Ed KC8SBV
ReplyDeleteI'm with you Ed!
