Re: [digitalradio] Re: More RSID - PLEASE!
Also, would it not be beneficial to have something like this implemented in the the unattended Pactor stations. A physical convergence layer for all. 73 philw de ka1gmn On Wed, Jul 22, 2009 at 9:33 AM, aa777888athotmaildotcom aa777...@hotmail.com wrote: You know what's really exciting?

[digitalradio] Re: Frederick Communications model 1102 HF modem
Thanks, but the password is the trouble... I asked NSG for support, bit it did not answer. Maybe because I do not qualify for a target customer ($$$)... I did contact with Steve (N2CHK), as he still has a old 1102 unit, but he moved and did not unpack your radio related material yet. Still searching... :) --- In digitalradio@yahoogroups.com, Andrew O'Brien k3uka...@... wrote: NSGD has a web site for maintenance documents but you need a password to access http://www.support.nsgdata.com/maintenance_customers/ Andy K3UK --- In digitalradio@yahoogroups.com, Luzem�rio luzemario@ wrote: Hello All, I got a old 1102 HF modem.

RE: [digitalradio] Re: More RSID - PLEASE!
You don't know if an instantaneously empty spot on the waterfall is truly empty until you send QRL? and receive no response, or monitor it long enough to have heard both sides of a QSO if one were in progress.

Re: [digitalradio] Re: More RSID - PLEASE!
Hello Scott, At the present time, there is a sort of SELCAL called Call ID (RS ID extension). However there is no protocol around it. It's just some information about the Ham (Call sign, Locator...) which pops up on the waterfall. More about Call ID: http://f6cte.free.fr/The_Call_ID_and_Prop_ID_easy_with_Multipsk.doc given a 2 second RSID transmission length 1.4 seconds precisely. 73 Patrick - Original Message - From: aa777888athotmaildotcom aa777...@hotmail.com To: digitalradio@yahoogroups.com Sent: Wednesday, July 22, 2009 4:33 PM Subject: [digitalradio] Re: More RSID - PLEASE!
