Re: Disappointed with 23cm digital data

 

The ID-1 is a good value if you use it's entire capabilities instead of only?the DD mode.
?
I use my ID-1s with analog FM & D-STAR Digital Voice repeaters in addition to the High-Speed (DD) data mode.
?
If one only wants to do data transmission?there are commercial data only solutions that are less expensive & offer faster data speeds. ?

I tend to agree with you on a lot of points here Ed.

Overall it's about 10 years to late like you said. But if there was a good deal I can look past some of that. Unfortunately I don't consider the ID-1 price a good deal.

As I have mentioned elsewhere, I'd like to see a stripped down version. No radio head, or analog/ DV modes, just DD. Perhaps only 1 watt. Something under the $300 mark.

I was definitely a little disappointed that the high speed data transfer of the ID-1 was not as much as I had desired and about 10 years late to market. But then again, we've got people still enamored with 1200 baud AX.25 packet, which is now only 30 years old.

Re: full duplex?

 

The RP2D is essentially just two ID-1's in a rack mount box.

See the photo's section of the dstar_digital group:

Thanks for the comments regarding my disappointment with the DD mode.

I seem to remember a ham in Canada using 2 ID1's back to back as a full duplex repeater. Has anyone tried this? Any downside? (except for the cost of 2 radios).

full duplex?
