It is a radiating dummy load, almost infinite BW. Probably more efficient than the incandescent light bulbs, people used back in the day, and poses a true 50 Ohm resistive load.

If you have an MB8719 on hand, I would try swapping it.

We communicated here not long ago, as I had an issue with something he had experience with. He was another one, that was here for the right reasons. 73 399

No. 3% is not uncommon these days. These new meters have very fast response to peaks, unlike the Bird. Bird Watts=Turd Watts dedkee, reeflek an arummmess. SL

As part of my employment agreement with a manufacturer I now refer to "Turd", I used my own Bird equipment, that was repaired and calibrated at 6 month intervals, at their expense. When it was time for repair or cal, the cal lab would condemn at least a third of my elements, as unable to...

Bird wattmeters suck, are overrated and it's time, for smart people to move on from them. There are much better things available now. SL

Have a look for MFJ-4035. I believe it is the same unit under a different name. Check this out, the cover is off.

I personally, think it is a worthwhile compromise.

The BW is a function of the diameter of the radiator and Q of the matching network. The inherent, narrower BW of the 5/8, results in higher gain lobes at the horizon.

That idea was used widely in military and marine applications.

Nothing you can do. If you need more BW, buy a different antenna. You could try soldering a 50 ohm resistor across the feedpoint. That should give you all of the BW you could ever want.

What is your <2:1 BW now?

same radio, different name.

Cable, I have both analog and digital. Things can be said about one or the other, but when looking at some of the things we do, at times, I prefer the analog. My digital scope was making me nuts last week, I was ready to throw it out the window. Had to get on the analog and I was good. Mine...

Pull the device and grab the screw with pliers or needle nose vise grip

Is the FT-991 not hybrid?

Can one still get a Hilberling?

You will have more luck on eBay. There are several radio dismantles that sell board level parts.

Why at least 100 MHz O'scopes are cheap these days in the used market.
