That's great news. Thanks so much for considering my suggestion. I'm sure I won't be the only one who will find this modification useful. Thanks again Simon.

Re: Signal history logging interval

Ken,
Today I’m adding the option to export with a user-selectable period, for example one value every 250ms, 500ms, … 10s.

Is there any was to adjust the logging interval in the ‘Signal History’ recorder accessible in the ‘View’ panel? I find it to be a very useful feature to track signal levels. However, it defaults to a logging interval of 50 milliseconds. While that’s useful for short-term monitoring of a signal, it results in some large files if you want to do some long-term monitoring, such as looking for sunrise/sunset effects, monitoring of Sudden Ionospheric Disturbances (SIDs), etc. With a sample interval of 50 ms, a 12-hour log will end up having 864,000 records. That’s approaching the upper limit for the number of rows an Excel file can handle. It would be useful to be able to specify the desired sampling interval to cut down on the number of samples logged over a longer time period.
If anyone can point me in the right direction to change the sampling interval, I’d greatly appreciate it. If it’s not possible with the current version(s) of SDRC, are there enough other people interested in such a feature to justify incorporation of such an option in a future revision of SDRC?
Thanks in advance. I hope everyone has a great weekend.

Re: Evenly spaced RFI.
jdow
7.059 MHz? Or might that be a typo on 7.159 MHz. That
would be the second harmonic of the old NTSC color subcarrier
which more or less lives on with the ATSC 59.94 Hz frame rate and
its harmonics etc. It could, in principle, be a very old TV
monitor on an old computer such as a Commodore PET at 7.159 MHz.

There is a particularly annoying node at 7.059 Mhz. It is roughly 6khz. wide.

Evenly spaced RFI.

I have a problem with RFI. It isn't in my condo and there is probably no real way of determining where it comes from but I'm curious if anyone recognizes this one.

The antenna is a magnetic loop on the balcony. Ironically I can null the noise but then lose the ability to get a decent swr as it is too close to the building. I know I will have to live with / work around this noise but I was just curious if anyone can identify it for me. Thanks and 73, Paul VA3ZC

Re: Pluto:: Spurious Emissions

Hi,
Juts looks like one bug fixed but for some reason it no longer transmits at 2.1 MHz and above :( . May take some time to find this, annoying!
The bug I fixed – the TX FIR filter may not have been applied…

Hi Simon,
i tried to register to the forum.sdr-radio.com. But i got no response to my email, also resend email did not help. Can you please check it? The reason i want to register to the forum is, that i want you to ask to add a maxim level hold function, i think that is very important option. Thanks for your great program, bye!

Hmm.. I see another small bug...after a bit of usage the tx buffers get a tiny bit mixed (audio is garbelled.. Sounds rough) Stop start solves it Dg9bfc sigi Am 17.01.2022 14:13 schrieb Simon Brown <simon@...>:

just made a quick and dirty test ... set rx to 10489.700 and let it there (switched of "sync") then sent a tune tone 500 kc higher and 1000kc higher (nothing could be seen on transponder!!) the did the same downwards (yes i know i was txing outside band!!) if there would be spurious signal plus minus 500 kc or 1000 kc i sure would have seen them (i was txing with 20w in a sixfooter!!) so ... i think its a different thing he sees on his station ... the pluto is clean (normally) so lets ask some questions ... any switcher used to power a predriver?? (switching psu frequency may mix up with the real frequency) or is it possible that you used an external reference on your pluto that is not clean (that also may cause unwanted signals) tx boost engaged?? no ... do not used it!! ... using higher power of the pluto sends out higher spurious signals so using tx boost does not clean up your signal better use lower power setting (drive 80 to 90 maximum) and add an lna dg9bfc sigi Am 17.01.2022 um 08:39 schrieb Simon Brown:

Re: Noise level variation AirSpy HF+
One final note, hit the square box in upper right to make it full screen. I didn't on the above image sent and the bottom ribbon bar is missing, most of which Simon needs to see when users are having issues.

Re: Noise level variation AirSpy HF+
When sent as an attachment (use the paperclip above text box) the image will not get reduced to unreadable. Maybe email clients can read it? But
I and others read it via the web GUI. Here's an example that all the finer details can be read. 73 Kriss KA1GJU
