RE: [digitalradio] JT65A reports
Hi Dave, Actually what you describe is EME reports as opposed to Terrestrial reports. The OOO and RO are used for EME but are also the defaults in so much as the JT65 modes were initially mainly used on EME. Either will constitute a good contact as long as RRR is exchanged. The 73 exchange is not required for either EME or Terrestrial and is really just a courtesy. Usually you will see new stations both in EU and the US using the EME protocol until they have gained some experience and or someone has explained how to send terrestrial signal reports. Hope this helps. 73, Barry VE3CDX/W7 _ From: digitalradio@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Saturday, January 05, 2008 9:24 AM To: digitalradio@yahoogroups.com Subject: [digitalradio] JT65A reports There seems to be a difference btween reporting systems between the US system and the European system on terrestrial JT65A contacts. Can anyone explain to me when a contact is 'valid' between two stations using the two different systems please? For example, I received the following today (callsigns obscured to not cause offence) on 20M 163700 12 -2 0.0 5 4 * CQ EA*** JM** 1 0 163900 10 -5 0.1 5 3 * G0DJA EA*** JM** 1 0 164100 6 -6 0.0 5 3 * G0DJA EA*** 1 0 164300 10 -15 4 3 RRR ? That was it, no report, not even OOOs. I was using what, in the guide, says is the European standard of sending the received dB signal strength, but the EA station was using the US version, appart from no OOO. A quick read through the excellent Bozos guide gave me the clue that the other station was double left clicking on callsigns (US system reports)and I am double right clicking (Eu system reports). Now, two questions occur to me at this point. 1. Is my EA contact 'good' or 'incomplete' and 2. What's going to happen when US stations and Eu stations work each other? I wonder why two reporting systems were created for terrestrial JT65A? My guess is that the US one will win out anyway, as that just seems to be the way these things go and left clicking is more the norm than right anyway, so why the alternative systems? Also, whilst I'm asking questions, why does double right clicking automatically turn Auto TX to ON? If you are not careful, and want to pre-load a callsign to call at the end of an existing QSO, you end up accidentally TXing over the top of the person working the station you want to have a go at next. This seems a bit like poor operating and it's not untill you do it for the first time that you realise what's happening... Thanks for any help with these problems I'm having - Dave (G0DJA)
RE: [digitalradio] JT65A reports
G'Day David, Well it can be a bit confusing I suppose in whether 73 is needed or not. I think you will find a lot of stations will consider the contact good once RRR has been received. The help file for WSJT states this if you hit F5. That said if you look at the examples of a minimal QSO for JT65 it shows 73. I guess it is an operator choice in the long run. I usually send it unless the signal is very weak, during a pileup on VHF or lack of meteors on MS. Have a great day! 73, Barry VE3CDX/W7 DM26ic _ From: digitalradio@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of David Sent: Saturday, January 05, 2008 1:10 PM To: digitalradio@yahoogroups.com Subject: Re: [digitalradio] JT65A reports Barry Garratt wrote: Hi Dave, Actually what you describe is EME reports as opposed to Terrestrial reports.

RE: [digitalradio] Announcing the Digital Radio Century Club JT65A New Years Crawl !
Hi Andy, It's a nice idea but bear in mind that with a perfect scenario the maximum number of contacts per hour would only be 12. A full exchange with a CQ thrown in would take 5 minutes to complete. Also because the text boxes are limited to 13 characters in my case it is not possible to call CQ DRCC VE3CDX - it will get truncated to CQ DRCC VE3CD. It will work though if I run the text together such as CQDRCC VE3CDX. The grid square gets thrown away though. If you are proposing using EME protocol then operators can edit the text boxes quite easily but if there are a lot of stations and there is QRM then it will be very difficult to distinguish who is sending RO EM00 - especially if there are two stations in EM00. Or if someone is sending RO and their DRCC number. If you are proposing to use terrestrial protocol then you can make it work as long as the operators do a lot of editing of the text boxes. And are very careful about spacing of the characters. If an inadvertent space gets inserted then some information is going to get missed. Just my thoughts. 73, Barry VE3CDX/W7 DM26ic As a point if interest the JT65 modes do not allow use of the /W7. There is a definite set of prefixes that the JT65 modes recognize but /W7 isn't in the list. In fact /W or /K are also illegal characters. The /W7 is valid with the meteor scatter modes though - FSK441 and JT6M. If someone works me on JT65A on HF they may think I'm in VE3 unless they pay attention to the DM26 grid. _ From: digitalradio@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Andrew O'Brien Sent: Sunday, December 02, 2007 11:05 AM To: DIGITALRADIO; WSJT Subject: [digitalradio] Announcing the Digital Radio Century Club JT65A New Years Crawl !

RE: [digitalradio] Digital Radio - Well Broadcast
IBOC is a method whereby both analog and digital signals are transmitted on the same frequency. Additional digital subcarriers are carried on the normal AM or FM analog signal. They extend beyond the normal channel bandwidth though so there is an increased chance of adjacent channel interference. I think the plan in the future is to eliminate the analog portion and have all stations strictly digital. _ From: digitalradio@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of John Becker, WØJAB Sent: Monday, November 12, 2007 5:25 PM To: digitalradio@yahoogroups.com Subject: Re: [digitalradio] Digital Radio - Well Broadcast This has been going on for over 25 years that I know of.
