Mike, As a side note, if you ever again come across a situation where the LM317 will not support the current draw that you need, you may look at its big brother, the LM383. It has the same form, fit,

Hi all, The 817/818 is a very reliable radio when it comes to external keying and one of you has confirmed the same behaviour when using a different radio. From the descriptions it sounds like RF

Sure does help, Ken, I'll get an order out to ?west mountain soon! I picked up a second 817 for $100. It was beat up but I got it working. There is a problem with the power jack, it's busted, and

Thanks, Steve for the info I take it a 1.8K resistor across the 817's power jack will fool the internal micorprocessor into thinking nothing is plugged in? The solution I was planning on using was

Oh, having a senior moment.... Yes, FT817 sounds a lot better mike wb8vge

Hi Mike, I use a 3d printed adapter with Anderson Powerpoles available on eBay. Refer to attached photos. Clyde KC7BJE

Mike, that power conditioner looks great. Without knowing how you have designed the circuits in the device, I am wondering if you have also (intentionally or otherwise) solved the excessive power-off

Mike, Thanks, your explanation answers my questions. Note: you seem to keep referring to the FT-817 as 718, which brings to mind a competitor's radio, the IC-718. Thanks, Ken, N2VIP

Hi, Ken, There is/will be a pigtail that runs from the conditioner to the radio. It simply was installed when these photos were taken. The active device is a low dropout adjustable regulator that

Mike, Looks nice, but I've got a couple questions: I only see one external connection, how is this unit connected to the radio? A jumper that passes thru the lid? I suspect most FT-817/818 users power
