Hi Gang

I have a Phillips 28V latching SMA relay - three terminals, one ground and two actuator.

Can anyone point me at a schematic driver such that a single grounded PTT line can drive the relay to switch one way when grounded and back when not?

I've seen this:

but it looks a bit complex?

Many thanks

Depending on the dimensions  of the brass strip but the modal makers shops ( model boats  etc )

are very good for strip tube and box section that can be used as wave guide

The best in my opinion is made by  K&S  Engineering Chicago . IL

Or if you fancy a bit of fun, do as this individual did

https://forum.419eater.com/forum/viewtopic.php?t=230851

when a scammer tried to rip him off for $220 for a non-existent ATU. He got the scammer to quote for ICOM linears, expensive rigs, BC108s, 4CX10000D's, and a whole host of other stuff where the scammer thought he was going to make over $20,000, so spent a fortune FAXing documents from Nigeria to the UK and numerous phone calls to an expensive (0701) mobile phone number in the UK

I've no idea who spent 6 months winding him up, but I'm sure they had a lot of fun!

Please don't use the word "hack" like that, either. Radio amateurs ought to know better, since they were the original hackers.

The group hasn't been "hacked". Someone has sent a spammy message, possibly someone whose computer has been compromised by clicking on a similar spammy message.

It has nothing to do with microwaves, and invites you to open an
