Re: Tinysa tracking generator

My hint is to use low level ( by attenuator or series resistor from Tinysa) to get the correct frequency response,calibrating receiver's IF section most? have agc control.

Re: Step attenuator for QRP transmitter to TinySA
I have one of these kits as well and was using it a few days ago in LOW OUTPUT mode to measure the MDS of a transceiver. What I found was that the attenuation level changed by a random amount just by

Re: Tinysa tracking generator
#feature_request
The tinySA has a very stable and accurate TCXO and output? can be between -76dBm and -6dBm
The frequency resolution is in the low part of the low output mode (below 45MHz) 156Hz and 312Hz above

Re: Tinysa tracking generator

Good stuff! You are in for a treat!
Start with the 455kHz stage, injecting a signal at the centre frequency just strong enough to detect. Align the detector first for best non-distorted signal.

Hello Dave.
Thank you for the answer.
I am radio engineer who most of the working carrier ( 30+ years ) was close but not quite with the radio related staff. My current project is a way to get back to

Re: Tinysa tracking generator

Is this a radio you have built, or a commercial radio that you think needs tuning? Just because you can, does not mean you should. The adjustment of a triple conversion superhet is no mere task for

Hello John, Sandro.
I would like to tune filters for SW radio. Radio has 3 IF¡®s 455 kHz, 10.7 and 55.8 MHz. BW is 4 till 10 kHz. Which ready modules for tracking generator would supplement TinySA

Hello Andrea.
I see different replay from Erik:

Re: Generator output level
Hi Erik,
Happy to know this is "normal ", and many thanks, if in the future, you can have this corrected.

Re: Generator output level
George,
There is a trick in the HW to extend the output levels down below -44dB. This trick depends on a, not so well specified, parameter of a component.
Up till now I have not found, using a

Hi Erik,
Thanks for your reaction. I will do the test off course. but...
I have never done a USB FW upgrade. I have a MAC OS. Do you know a site with a simple explanation to use the TinySA FW upgrade

Re: Step attenuator for QRP transmitter to TinySA
I have two Kay 475 attenuators. They have a series of toggle switches. You
can switch in 0 to 110 dB attenuation in 0.5 dB steps. The ones I have
cover 0 to 1.0 GHz. They are high-quality and worth
