can anyone tell me what the WILTRON 6407 RF ANALYZER does,is it the same as a vna,or more,cheers.

Just a casual observation / opinion. The device looks to be rather expensive for typical ham use to me, Unless of course you require testing capabilities in the 4.4 GHz ranges. The so called classic

"or" is left in the question :)

How do you update or does your nanovna-H4 look like the attached video? Link to get FW Hugen: https://github.com/hugen79/NanoVNA-H/releases

Well, Ollie, now you have done it. I have the Tiny SA and NanoVNA-H4. I have used them intermittently for some time, with the original firmware. For some reason, I decided this weekend to update the

Connecting to it might be tricky "witch can be used to connect DUTs with SMA interfaces." ;-) Just gotta find that nearest coven, I guess. ~R~ 72/73 de Rich NE1EE The Dusty Key On the banks of the

I see adverts for the SV4401A 4.4 GHz, 7-inch VNA from JNCRADIO, with N connectors.

Just use the 'measure / cable' function from the menu; it should work fine. It should report the impedance to be about 75ohm, and the length and loss of the cable. You do need to set the VF first. But

Using the NanoVNA to measure length of RG-6U cable, is it recommend to use a matching transformer (50Ω to 75Ω) or is that really just a moot issue? I have all the specs otherwise, such as VF.

I've run it with Parallels (but that's just running Windows in a VM on Mac). And with the new Macs based on a non x86 CPU, I don't know if one will be able to do that.

Windows is not necessary. Elsie runs in Linux in WINE just fine! I think there is something similar for Mac, too, so it will probably run there, too.

That is exactly as expected - what you have is two filter sections, one tuned to 44.998, the other 45.006. The combination of the two is fairly broad, but there's a dip in between. At one center

If anyone wants to fool around with a sort of idealized "two resonators in series" and how you can stagger tune to get a "bandpass" see the attached spreadsheet. There's another sheet with 4

Motorola provided 4 pole filters from matched 2 poles. The dot mark on each xtal must face each other. At their junction a proper shunt C to gnd is added. This sets the coupling factor for the 4 pole.

Saver reads the values from the nano as they are. If the nano is calibrated, Saver gets calibrated values. If you reset or disable the calibration on the nano, Saver will get uncalibrated data. Saver

Jim, filters are 45R15AZ from Aliexpress, but no datasheet found. Sold as equivalent to 45M15A? Nothing specified on couplage value. cdt

The S11 (return loss)? Most filters have a terrible return loss outside their passband. What you need to ask is "what's driving this" - will the reflected power out of band cause a problem? (i.e. make
