Interesting, thanks Gyula -- Mike

Try turning off WiFi and/or Bluetooth on RPI, I hope you lower the noise level. -- Gyula HA3HZ ( http://ha3hz.hu )

Thanks Stan. That sounds reasonable but is it fixable? -- Mike

For your first question, regarding how wide is too wide for HF VSWR measurements: I have one saved calibration setup from 1MHz - 30MHz, which I use to see the basic characteristics of a multiband HF

Actually, with 101 points there are 100 spaces, so divide the range by 100 to see the spacing. I didn't write the code, but I suspect that the graphics engine interpolates between actual measurement

I know that the nanoVNA has about 101 (measurement points between the start and stop frequencies. When using it for SWR measurements of an HF antenna, how wide is too wide? Should each band be framed

You can always spot the programmers... If they need to say go to: http://www.www.wwww.com They actually say: Goto: ... 73, and thanks, Dave (NK7Z) https://www.nk7z.net ARRL Volunteer Examiner ARRL

They are probably of a "certain age". 73, Gary - W6GVS

Really???? Dave E

We are all older than 25. DaveD

Yes, I've heard rumored that one could determine one's age by noting the first name. Yes, Dave D and Dave E are "about" the same age (we used to work together). How about Dave F? Dave E - W?LEV

Has anyone used this model outdoors? How readable is it in bright light?

struct Daves { char First_Name[50]; char Surname[50]; char purpose[100]; int dave_id; } daves;

Clearly you have not programmed enough... Should have ben Dave0, Dave1, and Dave2... :)( 73, and thanks, Dave (NK7Z) https://www.nk7z.net ARRL Volunteer Examiner ARRL Technical Specialist, RFI ARRL

Dave? Daves not here, man . . . :-)

Yeah, Dr. Seuss even wrote a story about “too many Daves”. You’ll notice that it is now DaveD, DaveE and DaveF. DaveD

Not another "Dave"... Welcome, Dave, (W0LEV) 73, and thanks, Dave (NK7Z) https://www.nk7z.net ARRL Volunteer Examiner ARRL Technical Specialist, RFI ARRL Asst. Director, NW Division, Technical

If you read /g/nanovna-users/wiki/16592 there is explaied how to handle the connector, e.g. see attached picture. 73, Rudi DL5FA

All, Please join us in welcoming Dave Eckhardt, W0LEV, to the role of co-owner of the nanovna-users group. Most of you have probably seen his posts to the group. He is well-versed in the use of VNAs

Get. The. Proper. Tool. If they make an insertion/extraction tool it is because it is needed to avoid damaging the delicate connectors on the cable or, worse, tearing loose the mating connector on the
