That is the simplest answer. RF will go where it wants to go. What you have there is a very unbalanced antenna system. A USB isolator may help. 73 -Jim NU0C "Erik Kaashoek" <erik@...>

Hi Erik, I regret to say that the localization problem still exist. I'm using comma as decimal separator in the Windows regional configuration and the program throws this error: "Range check errors"

Erik, The 'External Amp' setting is working on my installation.? In the screen capture below I have a 6dB attenuator attached between the 30MHz CAL out and the low port.? With -6dB entered in the

Try it with a good quality USB cable. Most big brand phone chargers come with properly built cables so that's an easy source. Most "replacement" USB cables are not build up to spec, no shielding, non

Make sure you install v1.1-7

New FW released Version v1.1-7 Changes: - Serial port integrated - Offset console command added to support External Amp setting from tinySA-App

BTW it works fine if I do it on the TiniSA screen! Joe

Hi 1.1-5 ge0ab998 And I see in the .ini file 'offset' according to the number I type in the box, but no change of scale ... I'll try to re-flash the FW TIA?? Joe.

Which FW du you run

Hi Erik So for me it does not... (other things appear to work fine!) Will wait for the next versions... Thanks for all the great work on the HW and SW ( you and OneofEleven) Joe

It should change when you? hit enter or when you do a scan Indeed, no units, just a number

Hi Erik Getting better and better... Somehow I don't get the "external amplifier" gain to change the displayed gain ....(I just type in a number like 25 and 'enter', no units?...) TIA Joe.

Just ordered one thanks for letting us know. Ed -K7OCK

Good info!I'll try that (choke on USB) and see what happens. Off to do more experiments and tests!Thanks again everyone!*** Walt *** WA7SDY ***

3 turns on a toroid ring

Did you use a clip on choke around the USB cable or did you wind the cable around a toriod ring I wonder ?

Only telescopic antenna connected, you see the MCU clock harmonics Inactive USB connected Active USB connected Adding a choke on the USB cable with active USB inactive USB with chocke Remember

Oh, you are using the telescopic antenna at the input and then you connect a USB cable. The USB cable is acting as part of the antenna and is picking up a huge amount of noise. The same thing happens

I get exactly the same type/pattern of interference show up on the TinySA/PC software when I have the TinySA's own little aerial on the unit and the unit plugged into the PC with comms running - it

Thanks for all the great info! Erik, I did hand tighten the SMA on the whip antenna. That is the only thing on the SA.? Martin,Was just reading raw RF in my apartment, whip antenna only, with full
