Hi Andy,

is LINKED by sending a GLOBAL ALLCALL. However, that will also stop

There are some issues with DBM ARQ in PC-ALE which will be going

during poor conditions.

The reason we don't have a nationwide wireless system is that it is not

Well Bonnie I don't know why your not hearing digi activity down at
7.030 - 7.040. In a half hour listening down on those frequencies I
copied 24 different callsigns, in this part of the world all the digi
activity is between those frequencies.

I have worked quite a few DX stations on both 7035 and 7070.
I see more long DX's on 7035more USA stations on 7070.
I see no Pacific area stations in any of those windows. I have worked

I dont know why anyone would want to put the PSK signals down at the low end
of the 40 meter band, where it has been customary for CW stations to work
for decades. 7.030 is in the lower portion of the 40 meter subband where all
the classes can go for CW, and they should not have to share that

I was thinking more along the lines that the Pactor 3 signal has 8 tones
and is a wide mode. Pactor 3 is a more complicated waveform and can
adapt to conditions and are likely raised cosine shapes.

I see that they have kept the PTT keying via detected audio, but the
addition of the sound card plus the USB interface is very nice. The
price seems incredibly low at just under $100 including shipping for
most versions other than the ones that require the 13 pin DIN plug which

Once could write a book on this topic. When you refer to noise, are you using a
CRT or solid state monitor? CRTs can generate a lot of noise and are typically
not well shielded. The easy solution for this problem is to ditch the CRT and
pick up a LCD monitor. As I mentioned in a previous post
My limited experience with PC-ALE has not been a positive one. The wide
frequency that the protocol uses can cause issues. Also, there is no way to
offset the centre frequency. I my case, I could not even get two computers
running back-to-back over audio cables to work reliably with PC-ALE. I
