Hi Stan I have tried everything possible to get this unit to connect to a PC. I did have one computer which I had not connected it to and it wouldn't work with that one either. I can only conclude

Have you tried to add a low pas or notch filter?

I live in North Central Florida. You can hear the traffic lights change on AM car radios, ell over a mile from those? crap LED traffic lights. The olny time I ge decent AM reception at home is after

Old car radios had a tuned RF input, and an RF amplifier. I't's hard to beat a '63 to late '70's? Delco AM car radio. They used a variable inductor tuning system, with very good tracking between

I recently ran across: "RTL-SDR Blog SMA Male to ..." on Amazon for $26.95. Ten different jumper cables with SMA Male on one end and an assortment of popular connector types, both Male and Female on

An AM radio antenna on a car is actually a voltage probe. I used to talk with Delco car radio engineers many decades ago at their annual schoolswhere they indroduced new designs to techs who did

You can get cheap cables from Ali or Ebay, just buy the semirigid ones and you should be fine. Hard to mess those up. I got a few cables like this one https://s.click.aliexpress.com/e/_DepHX0j and had

Pasternack made a high quality product when the company I worked for used them about 20 years ago. Good chance it is still a high quality product, at a higher price. Recently I have ordered components

Hello Stan, What model, manufacurer and from what supplier did you obtain the quality sma coax cables? Thanks. Al

Not me, but..... Pasternack is a good supplier, although a bit pricey. https://www.pasternack.com/ I believe DigiKey also carries their products. Dave - W?LEV

Glad you found the problem. These cables have been problematic from day one. I've even had a few with the NANOVNAs. Even a few bad USB cables. Dsve - W?LEV

It is not uncommon for the sma-terminated pigtail cables that come with the nanovna to fail, or to not have been assembled well. Sometimes the shield is not soldered at the connector, so it passes

Dave, W0LEV, It's looking like an intermittent good then bad connection with the NanoVNA. The nanovna is connected with the unit's supplied connectors/coax and additional connector as needed for the

Thank you for the reply. I’m a long time NVIS emcomm loop user but I just moved and purchased the H4 to build a new loop for 80 and another for 40. I’ve had excellent success using the 10KW common

How are you connecting the NANOVNA? Identical to the method used for the RigExpert? Where does the trace show on the Smith Chart of the NANOVNA? Is the trace consistent with the SWR indication? Once

The Nanovna h4 in use was purchased from R&L Electronics a year or so ago. Last month I updated the software. The Nanovna has never given me "good" results as compared to a RigExpert AA 650 zoom when

40-meters between your target times of 1000 to 1400 local will be problematic if the fof2 is not at or above 7-MHz. Here in N. Colorado, of late, it has been, but over the last couple of years during

Ok... with a capacitor, inductor, capacitor + inducteur you can do a fixed two band matching network :) Thank -- F1AMM Fran?ois

I have almost the same antenna as you. Over 40 m no station arrives harder than on my trap doublet at 12 m height. In general, a station arrives between -6dB and -10dB on the loop than on the doublet.
