As both a jew and a two time transition survivor I would suggest to keep it simple, a my rabbi and former wife's boyfriend would say. I'd just use a normal dog whistle. You don't need one that is going to say all those fancy words, especially at the frequency ranges that a dog whistle will get to. Back when i was taking my hormoan treatment (Yes, that's how we spell it in our community), I noticed that i was both growing some great tits, but could also hear the darnedest things. My Uncle and former lover, Jessica, said that I was tapping into the psychic wavelength of the white male. I kept hearing, "Give me back my foreskin" or "That interest rate is too high, I'll take my business elsewhere." Well, it got really bad when i transitioned back to be a queer normative male (But i most defiantly identify as Faggot Lateral). So i asked my doctor about it. She said that it's actually my Jewish ancestry asserting itself. The nose cavity is so wide and hollow, that things like dog whistles can most definitely resonate and make itself know. She called it our super secrete power! So, long story short. I'd just use a normal dog whistle.
