| MISC INFO HF via HT |
| Hello from Len // N8AD in Erie, Pa The information below rambles on and on a LOT! Sorry about that, but I wanted to put almost all the important information that I have in ONE SPOT. Use it for your reference for things that may appear unanswered anywhere else. |
| D T M F CONTROL FULL CONTROL VIA LOCAL REPEATER OR DUPLEX LINK. If You run EchoLink, MixW with CAT control of your HF radio, and lastly ARTiE, you will be able to control your HF radio using your DTMF pad and Touch Tones EchoLink does not need to be connected to the internet, it just needs to be present and running so that ARTiE can exist. Of course it is better that EchoLink can connect to the world via the internet, it's just not necessary. Once MixW is capable of controlling your radio via CAT, EchoLink's internal DTMF decoder will decode your touch tones received via your Link or Repeater, and pass the string of touch tones to ART. ART in turn will digest the code and if it is a correct one, will let MixW execute the corresponding command. (Of course this assumes that you have a repeater or link already properly interfaced to EchoLink, and it can decode touch tones.) In effect when you are in range of your Link or Repeater you will be able to send commands to place MixBASE in the RECEIVER MODE, TRANSCEIVER MODE, or just REPEATER MODE. (You can NOT be on a simplex link.) In the RECEIVER MODE you will be able to change frequencies to any that your radio is capable of going to. All commands will begin with a pair of "A's", which act as an attention prefix. Frequency changes are "AA" followed by FIVE digits. If you have used the CHAT TEXT box on N8AD's system, you already understand the 5 digit convention. Above 10Mhz just enter the KHz desired, such as AA14313, AA21390, AA28330 etc. Below 10 MHz start the frequency portion with a ZERO. 7233 Khz would properly be entered from DTMF as "AA07233". 3898 KHz would be "AA03898" and so on. Besides frequency entries via DTMF you can also enter memory channels. If you have set your radio up accordingly, there are 100 available memories with ARTiE. They range from 7001 to 7099. And of course they begin with "AA" ATTENTION signals. So to enter memory channel 50, which on most ART systems corresponds to 5.000 Mhz AM. You would send "AA7050" Notice 4 numbers. This is the reason that frequencies below 10 MHz all start with a ZERO, 7050 could be channel 50, or 7.050 Mhz, which would cause a lot of confusion for users calling CQ on top of WWV 5. Besides Direct Frequency Entry and Memory Channel Entry, there is overriding mode entries. By convention direct frequency entry will place the radio in proper MODE settings. A QSY to 14300 from 3840 will change from LSB to USB automatically. You can / must have the power to override this if necessary. So it too is available from touch tone control. AA11 is LSB, AA12 is USB, AA13 is CW, AA14 is AM, and AA15 is FM. The ability to place the system into RPTR/RCVR/XCVR modes is also available. AA01 is RPTR, AA02 is RCVR and AA03 is XCVR. AA00 is STOP, which will also place it in RPTR as a default mode. We discussed Direct Entry of frequencies, and they will provide whole KHz entry. To fine tune to the nearest 100 Hz, are 2 other commands, AA?B and AA?C. AA?B, where ? = a number from 0 to 9 moves up 100Hz X ?. So if you were to send AA4B, for example, you would move from the present frequency, say 14300 to 14300.4 KHz. AA9C, on the other hand would then move you down 100Hz X 9 or to 14299.5 KHz from the last entry. Want to know what frequency you are on presently, Which is a good idea if you plan to do any transmitting. Simply enter the command 'AAAA" and K1RFD will reply with the present Frequency and Mode. AA10 will send the time of day. If you set your radio up to comply with our convention,you will place the 10 meter FM repeater pairs with proper splits in memory channels 7061 thru 7069.We have standardized this to be, if a user sends "AA7064" for example, the radio will be set to memory channel 64. Channel 64 will be pre- programmed to contain 29.640 for receive, 29.540 for transmit, SPLIT will be activated, and the FM mode will be selected. This standardization is important to us, and makes operation of 10 FM easy for all involved. Channel 7060 DTMF "AA7060" places you on 29.600 FM simplex. The national calling frequency. Memory channels are very useful, as you can see for providing splits PL's and offsets that are not otherwise easy to do from the field. Numbers below 40 are pretty much reserved for REPEATERS on VHF and UHF, for just this reason. Since you are also on a VHF/UHF system, you might not want a non-informed user setting direct entries on these bands. It would be disastrous for someone to transmit on your control frequencies. Memory channels let you select what can be used in these dangerous areas. (It also keeps desense issues to a minimum!) Similarly, we have chosen that 60 meter channels be set up on 7091, 7092, 7093, 7094, and 7095. With non standard Modes of USB preset. Channel 99 is saved for NOAA or weather radio broadcasts if you location and radio are so equipped. There could be more in the near future...If you have a need for something that everyone might want, drop us a note with the request for your desired function. The ART team.

| Hints for proper operation... The MixBASE system on N8AD-R is composed of three separate elements. 1...It is a Repeater system that simultaneously sends the active audio on RF . Please listen to "something" if you use the system. DON'T just let it play NOISE! 2...It is a RECEIVER that also streams audio over eQSO, SKYPE, and PORTRAIT. Be sure to turn the system ON with the ON command, then send the RCVR command via EchoLink Chat. 3....It is a TRANSCEIVER if you are entered into the XCVR, Control Ops Data Base. 4...When you are finished with a session, be sure to turn off the system, if you entered commands to use it. Enter STOP, OFF, or QUIT to stop the receiver, and return it back to REPEATER control. 5...If you connect and you are the only user on EchoLink, do not be alarmed if the receiver is ON. The repeater also offers full control via Touch Tones, and we use it all the time to keep audio playing for all the "Listeners" on other systems. Feel free if there are no EchoLink users already, to tune it to whatever you desire. 6...If you connect via EchoLink and there is another station(s) already there...Do not steal the system away from previous users. There is only one radio, and one user at a time that should control it. 7...You can speak over Streaming Audio from the receiver if the system is in the RCVR mode. Send "TALK" in Chat to mute the audio. When you finish transmitting send "LISTEN" to reset the audio stream. 8...EchoLink will not allow the EXACT line of Chat Text to be duplicated within a 30 second period. It will ignore a duplicate entry! This is a primary reason to use EZPAD or the ART-DX download GUI's. 9...Shut off your CHAT TEXT CHIME. If you receive a DING whenever a line of Chat Text is received, it would be wise for you to shut it OFF, before it drives you crazy. (Same with the You are DOUBLING WITH message.) 10...eQSO also streams this station's audio. If you intend only to Listen it would be considerate of you to do so from eQSO since it will not use bandwidth from me. If you want to set a frequency to listen to, you must remain in EchoLink. The room to connect to in eQSO is the HF_RADIO Room 11...SKYPE is also available and is connected to, one user at a time, by dialing "hfremote". Both SKYPE and eQSO are not monitored locally by anyone (except only occasionally). 12...Don't ask for XCVR privileges unless you have downloaded ART-DX or EZ-PAD and have figured out how to use them from a RECEIVER standpoint first. All users can do everything up to the XCVR command without needing approval. 13...If you are in the Control Op data base and intend to use the transmit functions...BE SURE your audio is as perfect as it can be. Voice peaks must go to YELLOW on the Audio Meter of EchoLink without going full scale! Failure to talk it UP to this level will result in LOW OUTPUT from the HF transmitter. POOR AUDIO from you will result in really TERRIBLE AUDIO on RF. 14... This system can do ALL DIGITAL MODES ! Using REALVNC VIEWER 4, you can even do SSTV etc. 15...There is a delay from the time the HF station says OVER until your audio can return to HIM over the air. This is due to EchoLink and can not be entirely eliminated. Set your RECEIVER HANG TIME to 300ms and reduce your NETWORK and PC BUFFERING to minimum values that will still provide good audio that does not break up. (The best it can be reduced to is about .6 seconds.) The station on HF can respond to you immediately, and does not have any delay to consider. Your response to him will be delayed, only! He does NOT have to drag HIS feet when returning to you. 73 N8AD |
| Normal System Operation Instructions. If no one is already in CONTROL... 1...SEND "ON" in CHAT or CLICK the ART-DX "ON" button. 2...SEND "RCVR" or CLICK it. 3...SEND a FREQUENCY in 5 DIGIT format such as 14300, 07258 03950. FINE tune using 03950.123 etc or if using ART-DX click the EZPAD button above the MAIN TUNING dial of the radio, and use it to set the BAND and frequency. 4...Send COMMANDS or click ART's buttons. Proper syntax is required if you use CHAT. 5...When finished....SEND STOP !!!! 6...Disconnect for others to use the system. DON'T LISTEN TO STATIC...SHUT IT OFF IF YOUR NOT GOING TO TUNE IT TO A STATION! KEEP IT IN THE HAM BANDS ONLY, and DON'T USE IT FOR SWLing. |
