I really enjoy your news articles. Very inspiring!!
My entire ham hobby has been focused on digital communications. I figured I would leave some comments that maybe you can address to inspire other hams that this newsletter reaches.
I have been using Direwolf these past few years and have been trying to incorporate it more in todays world. I have enabled FX.25 on transmit knowing if there are any other Direwolf stations out there, they would receive the error-correction (less chance of a re-transmit on one side of the link). And to those stations not Direwolf, they would still receive my transmission. I realize IL2P is much better for error-correction, but I am thinking of backward compatibility.
Another idea would to use Direwolf to upgrade stations to 2400 baud packet. Nothing new would be needed since it still uses the same-ole audio interface.
I use 1.25m for packet. WOW!! What a difference!! I get the range of 2m, but little to no noise. I have been using BCM-220's and they work great (I have tested them up to 19.2k - No range checks yet until summer). I hope Alinco will do the new model right. I owned the DR-235's and they could not perform at 9600 baud (hardware limitation - they have a resistor in-line limiting bandwidth).
I have also been experimenting with LORA APRS with the T-Beams on 70cm. I still need to do some range checks. Very promising. For new I have been enjoying Mechtastic with T-Beams on 915Mhz.
Again, thanks for your newsletter and the efforts you put into it. Enjoy!!
Doug - Thanks for the kind words about Zero Retries. Agreed - 222-225 MHz is an under-appreciated resource for US Amateur Radio. I have hopes for the new (?) Alinco radio and the BCM-220. I've heard mixed reviews on the DR-235s; I've read that the earlier units seem to perform reasonably well at higher speeds, but the newer (redesigned for manufacturing in China?) units less so.

Keep up the good work! Love the newsletter

Juan - Now that is interesting! Thanks for pointing it out to me. I'll be mentioning this in Zero Retries.
