Re: How do you measure a car antenna?
I don't like to be the bearer of bad news, but the dealership has no idea what RFI is. They know the words and there is a problem with some Jeep models, but that's as far as they go. Experience

Re: How do you measure a car antenna?
Same here - they showed a little squares, a few pixels wide, and both appeared the same way and to have the same content. I use e-mail to access the group. Cheers, David -- SatSignal Software -

I have used Ali many times over the years, in particular Zeenko. I have never used my card but always PayPal and usually by messaging the young lady, whose name escapes me. She has always produced a

Re: How do you measure a car antenna?
Unfortunately I can't see any photos. Maybe it's just me or maybe they need to be posted to the photos section? I don't know how the group is set up. While it's hard to compare radios between

Re: How do you measure a car antenna?
At the risk of being slightly OT, there are several reasons that AM radios are disappearing. One is the EMI problem caused by various vehicle charging and propulsion systems. The EMI issue is a

Re: Not available at Ali Express / Zeenko
I see all of the products listed. Please note that product visibility depends on your country of delivery. A year or so back I could not see any products in his store unless I changed my shipping

Re: How do you measure a car antenna?
Ken, looking through FCC part 15 rules on emissions, I don¡¯t see any exemption for electric car motors or power systems. Do you have a reference to a FCC document for the exemption you mentioned?

Re: NanoVNA Saver frequency axis weirdness
Okay wait, I see what's going on here. The frequency graduations don't really match the labels. What I took to be a vertical line at what is labeled 146.2 MHz is really lower than that frequency,

Re: NanoVNA Saver frequency axis weirdness
Hi and thanks for getting back to me... I manually set the markers in VNA Saver to match the markers set on the VNA - double checked this a bunch of times. Marker settings everywhere match. See

Re: How do you measure a car antenna?
Take it back to the dealer and insist that they fix the problem. The problem is poorly designed and implemented inverters for the battery and electronics. It probably does not meet part 15 FCC rules

Re: NanoVNA Saver frequency axis weirdness
Note that the markers in nanovna-saver and the nanovna display are set independently. Did you manually set those specific marker values in Saver? Or were they automatically set by saver? Do the marker

Re: Trouble calibrating NanoVna Classic after upgrade to 1.2.20
You set me on the right path, Dragan. I went ahead and found the latest firmware for the Nanovna classic (not H), version 0.8.0, and it worked ok so I'll stick with that. It is interesting that nobody

NanoVNA Saver frequency axis weirdness
Sorry if this has been addressed already. I've made attempts to find some discussion of this here but so far unable to track it down. The frequency axis in NanoVNA saver (0.3.10-Win7, same for 0.3.8)

Re: How do you measure a car antenna?
That¡¯s great. Come up with a technology like EVs that appear to exempt from FCC interference standards, and make it ¡®acceptable¡¯ because it¡¯s ¡°¡­good for the environment¡­¡±. Any other

Re: How do you measure a car antenna?
Most of the biggest stations on the AM broadcast band around here are also simulcasting on the FM band and internet streaming now. They probably saw the trend happening in car radios before I did. It
