Sounds interesting to me Paul.

Anyone one else in the group interested?

QRP....."more smiles per watt"

   It would be a fun amount of learning for me. Nothing too official--to help keep the cost down. I just came across one project that covers the freq. range of 3.5Mhz, to 12Mhz. It uses a "Far Circuits"   
   board. What kit(s) did you have in mind? I wonder what limitations have been over come with time and practice.  shawnr kf7yff
   

 

Wayne & all,

The only reason not to have all the grounds tied together is in case there is an older rig that uses high voltage, negative voltage, in the keying circuit like some of the older Kenwoods that had tube finals and the Heathkit tube rigs.  Some people still do have them ya know, hi hi.

 

If that were the case, one could get into a bit of trouble due to voltage feedback on the ground circuit keying rigs that weren't supposed to be keyed.  

 

I really don't see a problem with it as 99 percent of the rigs today have + voltage on the tip circuit in the Jack and most everything is solid state anyway, but like I said, there are still that 1 percent of the older rigs in use.

 

I'd bet that most people who have the older rigs would be using opto-isolators or reed relays of some sort when using a solid state keyer for CW.  Mechanicals such as hand keys/bugs wouldn't be a problem except for the possibility of the negative voltage on the old grid-block keying rigs affecting the newer positive voltage keying circuits.  The other problem would be that a grid block keyed rig usually had a negative 80 volts or so on the key jack and that might prove detrimental to any solid state devices unless they were designed to handle high voltage.

I agree, you should not tie all the grounds together, it can cause problems... been there done that.

You can get a 3 pole rotary switch from Jameco and that will allow you to switch 3 circuits.  You'd want to do this if you are using an iambic key.

You will need to mount any jacks used on a non-metalic surface to keep the ground circuits isolated from each other.

BUT, I have all the isolation I need inside the electronic
keyer. I just want to switch it's output to multiple rigs
and not sure if I need anything to protect from RF etc.

I'm looking into this for a friend and he wants to use his
keyer on 4 seperate rigs without plugging and unplugging.

I don't see much of a problem with just switching the output
of the keyer.

Just curious if I need to protect the circuit in some fashion.

Guns don't kill people, any more than spoons & forks cause obesity.
I guess most people don't think because it's too tedious for them!
What I like about naps is, I can get them done while I'm sleeping.
If they can, they do; without thinking if they should.

 

 

I seem to be having a problem getting email delivered to:

sss at 4sqrp dot com ??

Am I misreading what it on the web site? Or just plain messing up  the address.... heh heh

 

In any case here is my sprint log such as it was.

I'll keep trying to get it to Walter via the sss address.

 

72 for now,

Hey,
It's not much but all I could manage for the short time  got to play.
always fun and looking forward to the next one.
