Enhancement - Asymmetric TX / RX data rates

[stevestroh]

(Apologies if this is already a feature of Dire Wolf. I haven't dug deeply into the configurations to see if this is doable now, but wanted to capture this idea just in case it isn't.)

Bill Vodall W7NWP:
Wild idea this morning when mentioning to a friend that the IC7100 will receive 9600 with the internal modem but cannot transmit (darn transformers?) at 9600.

Maybe it doesn't have to run 9600 on both up and download. Perhaps it could receive at 9600, like from a tcp file server, and send the ACK's back at whatever speed worked - maybe 2400 or 3500.

If we have flexibility to configure the soundmodem separately for transmit and receive channels - it opens up options to tune systems to get the best available speed.

I haven't fired up/compiled DW for a few months so I don't have an up to date running instance to check. Maybe this is already there. If not, maybe it'll be a low hanging tweak.

Another interesting idea this would open up is the possibility of using an inexpensive Software Defined Receiver as a separate receiver, which could receive a higher speed signal (such as 9600 or faster) paired with an inexpensive transmitter (such as an inexpensive portable radio) that cannot do the same higher speeds as the receiver.

The situation I have in mind is the use of a FM repeater that would transmit data such as files - code plugs, maps, etc. (perhaps using a technique like Radio Mirror) at higher speeds like 9600 bps or faster. To receive the transmissions only an inexpensive Software Defined Receiver would be required, coupled with Dire Wolf. To transmit (such as to request a file transmission) only a low speed - 1200, 2400, or 3600 - whatever would work reliably on an inexpensive portable radio would work, again coupled with Dire Wolf.

In this scenario, the "server" Dire Wolf would need to be configured as 9600 (or faster) TX, and 1200 / 2400 / 3600 RX.

The "client" Dire Wolf would need to be configured as 1200 / 2400 / 3600 TX and 9600 (or faster) RX.
