Andy,
**However, if ALE-400 ARQ is getting through with error free throughput, what
are the chances that Olivia or Thor or some faster mode is getting through with
much faster throughput and a only a few errors ? Other than a wider bandwidth,
the other mode may turn out more efficient.**
Another unique aspect of ALE-400 is it's bilateral operation. Since both
stations can type at the same time, text from each station passes
back-and-forth ever few seconds allowing the conversation to change
directions quickly if need be. The bilateral wpm rate is 85 wpm or 42wpm
each way; the
I did not transmit afterall, I need to do more research in to the legalities
for USA hams.

Hello Andy,
If RFSM-8000 derives from MIL-STD-188-110A (implemented in Multipsk), it is
not legal in USA because the speed modulation is equal to 2400 bauds with a
limit of 300 bauds in USA (you can't TX in 110A in USA). It is really a
shame.
Note: even if the (useful) bit speed is equal to 75
Thanks Patrick, I guess we will have to lobby for some changes.

So what would be the lowest band we could use it on? 10 meters? 6
meters? Higher?

All,
Couldn't wait to get my 80 meter end-fed up today so we installed it temporally
as a cloud-warmer just 15 feet off the ground. I'll be QRV for a few hours and
would like to make a few contacts. I'll be on the sked page.
Thanks,

It's all spelled out in PART97 in 95.305 and 95.307.
On 6 meters, you can go up to 19.2 kb.
On 10 meters, you can go up to 1200 baud.
Below that, 300 baud is the limit.
Note that several HF digital modes try to evade the 300 baud limit on the low
I use 188-110 at work and it is still not a barn burner for data rates although
it is fairly dependable. Most days lately with no sunspots it has been 600-1200
bits per second and this is using a considerable amount of wattage on both
ends.
So please do not get your hopes up too much. It is
