Re: Tune Button

How does that meet your requirement, Mike? All you need is the disable PTT part.

In fact, why not just use an external switch? Or an external switch controlled by an OC output. Or an external switch controlled by a DDUtil macro button.

Re: A "jangling" artifact on TX and RX audio, related to filter size?

The other thing to consider is that this setting is much less important on transmit. As mentioned above, at 1024 the skirts are already much steeper than any other radio out there save the Flex. You are not going to look or sound bad at 1024 transmit. So you can knock that setting down to minimum on...

Re: A "jangling" artifact on TX and RX audio, related to filter size?

Buffer size should have nothing to do with this issue. It would be good if you would confirm that is the case. What this is really about is the transient response of the filter skirts. This is not ringing per se, but it is a time domain, transient response issue. There are three things that cause tr...

Re: RX2 not same signal level as RX1

Mike, If you've been following the above examples, in every case the problem was a hardware failure of some sort. N4XD did not report a lower noise floor, he reported lower signal levels. Is that what you are seeing? Assuming you've done your part in identically configuring both paths in the softwar...

The DDUtil "autodrive" feature can be very handy for this sort of thing. You may wish to take a look at that. If you are not familiar, DDUtil is a "helper" program that has all kinds of useful talents. See here: viewtopic.php?f=16&t=3040

DDUtil will not be able to do this for you. You could write a script in something like Python or Java that automates this, sending the correct sequence of CAT commands and recording the results. However, you are in luck, because a tool already exists that can do this: SWR Plotter . You will need com...

Re: IMPORTANT UPDATE/DO NOT USE: 7000DLE fan noise fix

If it's the PWM "rattle" that's bothering you, simply rewire the fan directly to 12V. If it's the fan itself you might do a little better with a slightly quieter fan. Others will have to suggest what make/model to get, I can't guide you there. If that's still not good enough then you will ...

Re: Coupler Solutions

Short answer - maximum PS feedback level is set by the no damage max. input level to the hardware, which is +13dBm. - minimum PS feedback levels needs to stay above -10dBm, below that PS performance will suffer. However higher input levels will provide better SNR vs. internal crosstalk; this is more...

Re: Transmit Audio Monitoring Suggestions

Unless you are one of those humans who is immune to listening to an echo of themselves, it is effectively impossible to do what you want because of the latencies (delays) inherent in the openHPSDR software architecture. If you eliminate all audio processing in Thetis/PowerSDR: limiter, pre and post ...

You can obtain CAT control of an SPE amp either directly from PowerSDR/Thetis or via DDUtil (make sure you use an older version that still supports legacy software--newer versions only support SmartSDR) as long as you have your serial cable built properly.
