Erik.... are you really the guy that made these? That's awesome to be a beginner and get an answer from the creator. So thank you for that. What accessories would you recommend? Is a VLM-33W-2W-S+

Dear all, Finally the parts arrived, and I started the IC changes. First, I removed the U22 0 ohm resistor, working as jumper, and place the RF Switch, and do recall. During recall it fault again,

No need for self righteousness. There are RF environments where strong signals can flood an antenna. I can see why such devices would be useful. But I am nowhere near such a RF environment.

Trying to replace Input RF switch U22:? AS179-92LF LNA U14: BGA2817 might need to be replaced Attenuator U28: PE4312C-Z Good luck.

Thanks. I inaugurated my cheap hot air station and the RF switch gently came off. Now i could jumper it to check the attenuator, but i prefer waiting for the spare part and soldering paste, and keep

Is this one a clone? because if not, I'd be keen to try and replace the attenuator, or go through the trouble shooting more closely and try and fix it.

Maybe, no -- Designer of the tinySA For more info go to https://tinysa.org/wiki

What you are observing is indeed possible as the switch can fail in?different ways -- Designer of the tinySA For more info go to https://tinysa.org/wiki

Hi I bought tinysa ultra from facebook. It fails attentuator and signal level. Can it be fixed? can it be used as a signal generator?

Hi Erik, yes i performed the manual routine and think it is useful. I have a low signal level on my Ultra 407, down by 40 dB, i.e. at -75 dBm. Now your manual says that even with a bad RF switch, if

Comment regarding the interval time of 32.6msec that I used. ?An exact multiple of 1/60 would have been 33.3…..msec but to get a stable display I had to set it to 32.6msec. ?Difference is likely

?If I remember right, the HP network analyzers have a ‘skip isolation’ option in their cal routine, making me think it won’t make much difference in most cases - especially in a Nano.

Hi Erik and gang, I owe Erik an apology as not to long ago I said the interval triggering feature that Erik implemented for me a few years ago on the TinySA was not working properly on my TinySA

WinSpectrum III v3.0.1.1 – Update & Fixes Some users reported that nothing was displayed on the graph when using tinySA (basic). The issue was caused by WinSpectrum's default scan setting of 450

No this is not just an attenuator. It is a limiter with silicon devices. You can buy limiter diodes and build several yourself if you don't want to pay $63 for good insurance. That's your decision.

So help me understand... This is basically an attenuator, but only for signals above a certain threshold, letting weaker ones through without attenuating them? Matthew KD6KVH

Below is an update on the schedule of speakers and presentations for the Southeastern VHF Society Conference. The conference will be held at the Quality Inn at Exit #4 in Clarksville, TN April 4-5,

1) Yes, for isolation, both ports should have a non-reactive 50-ohm resistor installed. 2) It's excellent insurance to install the following on each port. From MiniCircuits:
