Variable-frequency oscillator

Yeah.

And they had a little VFO, also a tube, and the capacitor.

I know you're always on the look for those variable air capacitors.

He gets them from Italy, and a man there, a ham there, hand-makes his own variable air capacitors.

And they're beautifully made.

And he had that on display in his VFO.

So I got the half-watt 40-meter CW capacitor.

transmitter but he had another one that puts out a little bit more power and it has a vfo with it mine's crystal controlled on 70 30 but i'm going to put that together this week and see how it does on the air it'll be a great little uh really a cool device but hollow dash state designs and it's their qrp now you do have to have i found a little power supply for it on on amazon And it puts out 230 volts.

Lynn has released a new controller called the CTR2 Max, and I have put a link to that in the show notes.

This thing has four knobs, four buttons, a VFO knob, and a really big display.

It's not using the M5 stack tiny display in the middle.

Um, I'm fortunate enough to have received the first production unit that he built 'cause he made the announcement and he showed a picture of it, and I'm like, "Yes, I want it." And I replied to him in, uh, it had to be about 45 seconds.

You have continual s-

...

VFO and you have continual-

Yeah

So yeah, that nice feature they talk about has a vulnerability in it.

Uh, has a vulnerability two in a guest pass VFO lock bypass via apply VFO profile.

Has a vulnerability three, TX enable, TX power gate bypass via CW keying.

[laughs] So this is interesting.
