Hi Stack,

From the email you just used to reply to:

than "Re: Contents of Discuss-gnuradio digest..."
... I changed the subject line for you. Please directly subscribe to the mailing list if you want to actively participate, it makes everything much easier for you!

As a comment on your question: This is impossible to answer.

When asking for help, please take the time to not only put it into a proper shape, also think about what the other side would need to know to help you. Getting free help from other people is a valuable thing – try to make the most of it!

Generally, every question you start a conversation with should explain, at least:

* What is the higher purpose of what you want to do?
* Why do you consider doing it this way?
* What have you tried so far?
* Where did you get stuck?
* Can you formulate a clear question that someone who knows the project but is not involved in whatever you're doing could answer?

Best regards,

Marcus

Greg,

glad to hear it's working overall!

The PyBOMBS recipe in gr-recipes points to 'master' branch, which is
tentatively tagged as version 3.11. I'm curious why you'd get the LTS
version. Can you give any details on how you installed PyBOMBS and
gr-recipes?

Cheers,
Martin

Subject: [Discuss-gnuradio] Problems Changing USRP Sink Center
        Frequency During Runtime
Message-ID:
        <CAGN87Oi=LC7pzxU5CZZ4NsT4ERYGaddress@hiddengmail.com>
Content-Type: text/plain; charset="utf-8"

After about a week of debugging why I was having trouble receiving multiple
AX25 packets when sent together, I've discovered the issue seems to be that
if the initial center frequency of the usrp sink is not the frequency that
it is changed to after it starts running, then the problem surfaces.
Tweaking parameters in other blocks, like quad demod and clock recovery mm
have had almost no impact.

The code is supposed to allow the center frequency (and other parameters)
to be changed while running, which is why just setting the center frequency
to the frequency I'm using for testing is not the best way to solve this.

What sending multiple ax25 packets look like. There's a single 0x7E between
each ax25 packet, which is allowed by the specifications. Also, an icom
radio works just fine, and it's in a different room.

<~100 bytes of preamble> <AX25> <AX25> <AX25> <AX25> <postamble>

Also, if the radio is sending one ax25 packet at a time, even when the
starting center frequency is 100 MHz+ away from where the radio is
transmitting at.
