End of the line voor de DVRPTR V1
De DVRPTR V1 wie kent hem niet. Met dit kastje was het in de vroege jaren van DStar mogelijk om met behulp van een PC of een Raspberry Pi “over the air” toegang te krijgen tot het netwerk. Inmiddels is de productie gestopt en dit heeft alles te maken met het verschijnen van MMDVM zo schrijft Bruce Given op zijn website.
PRODUCT DISCONTINUATION NOTICE
After careful consideration, I have decided to discontinue the manufacture of the DVRPTR V1 boards, effective immediately.
As a replacement for the discontinued DVRPTR V1 boards, we will offer a much better alternative: the MMDVM (Multi-Mode Digital Voice Modem).
The MMDVM is a faster, more versatile and less expensive product capable of operating both in repeater and hotspot mode. The MMDVM is currently working with D-STAR, Fusion and DMR and there has been significant progress with P25.
Please visit the MMDVM site for more information: http://www.mmdvm.com
Also, you can follow us on Facebook or become a member of the MMDVM Yahoo Group.
As always, I remain committed to providing with the highest quality products and service.
