Small latching relays for RF switching


 

Has anyone know of further experiments done along the lines of this, but with smaller relays suitable for portable/QRP applications?



I see the IM43 relays being used in the (tr)uSDX

Axicom D2n relays have been swapped into the uBitX.

Stock uBitX uses VRS2H, which is hard to find.

Browsing the digikey catalog there are several other series of small latching relays that I don't see any reference to (in ham related gear, at least). Has anyone played with the alternatives? Anyone have data?
