Skip, I had two contacts today and transferred mail and files with both
stations.
We started out on PSK125 and dropped to PSK63. We had strong interference
from a Pactor (1 and 3) station. FLARQ managed to work through the QRM
and get the files transferred. In some cases we had a lot of retries but it
worked.
We did this between Illinois and Texas, and between North Carolina and Texas
so we did not have the benefit of NVIS. This probably increased our retries.
Can we control the size of transmitted units? Or does the program reduce unit
size in difficult conditions?
Thanks for a great package. We will be trying it out on VHF as well.

Hi Russ,
Sorry I have to rain on the parade, but I am now in South Carolina, and no
longer in Hawaii. :-(
However, what is significant is that even with band conditions degrading
rapidly, you managed to send me a message using Flarq, and it was received
flawlessly with only one repeated block.
I was running 10 watts to a 20m inverted Vee in my attic (on 30m!) to your 5
watts with a Butternut in the side yard. Band was going out, but because we
were using ARQ, the message came through without an error, even though the
raw text on VBdigi had errors.
If I had a 30m antenna, I would have been much stronger. I am amazed we
could had a QSO at all, under such poor conditions!
You are my first totally random ARQ QSO using the NBEMS, and I connected
with your beacon signal, so I am very gratified with the result tonight!
