[digitalradio] Digital Voice Freqs 40m / 80m
I was just talking with Ken WB6MLC today. Ken has been leading the HFpack Digital Voice project, which has recently increased the DV activity on 40m (and 80m) significantly. This group of DV ops, in mostly western part of USA/Canada is now meeting on the following frequencies: Digital Voice 40 meters 7291 kHz USB Primary 7286 kHz USB Alternate Digital Voice 80 meters 3991 kHz USB Primary 3986 kHz USB Alternate There is a 40meter DV net on the weekend, and at other times, operators are encouraged to call and monitor using HamDRM, G4GUO, AOR, and other DV formats. The frequencies are within the General Class bands for USA hams. 73---Bonnie KQ6XA . Need a Digital mode QSO?

[digitalradio] WD8ARZ and upcoming ALE Week Status
Looking forward to the upcoming week for ALE ON THE AIR WEEK 2006 (13-23 OCT) In preparation for this I have done the following: -- Have put up a new 10-160 Meter Carolina Windom Bought a LDG AT-200 Pro tuner Bought the Kenwood TS-480HX 200 Watt Transceiver -- Thanks to Steve N2CKH, I now realize I need the LDG AT-200 PC version of the tuner. (... as only the AT-200PC is really suitable for ALE, the other LDG models such as the AT-200PRO is not in BYPASS during receive whereas the AT-200PC is set to such via both PC-ALE and MARS-ALE software ...) The LDG AT-200 PC version will be ordered on Monday and will be here in time for the weekend ALE fun. Reason I have made the changes is I have been concerned about the ALE burden on wearing my beloved FT-1000MP relays to death, This concern has limited how often I am on and stay on with ALE. What I hope the benefits with the changes are: 1: TS-480HX doesnt use relays in the bandpass filters (uses switching transistors, but does use relays in the lpf filters) 2: TS-480HX has excellent cooling and better continuous duty transmit time and load support (even with the dual fans not running). 3: With the 200 watts, I can use it if needed, but it allows for running lower power and having better cooling and transmit duty cycle time even more. 4: Using an external tuner transfers the relay cycle mechanical wear to out side the transceiver. 5: The LDG AT-200 Pro tuner has memories, and once stored settings for a frequency are in memory, it makes those tuning selections even faster than other tuners . except the PC version under computer control). I am keeping the Pro version because I want a good fast tuner for HF operations with out using a computer. 6: LDG AT-200 PC under computer control is the best way to go for ALE, and I very much appreciate Steve supporting the manufacture on bring that about! Only thing missing at this time is a ALE version that supports the TS-480HX and LDG AT-200 PC tuner. Currently waiting on replies to Steve, Bonnie and Charles for software access to support this system in time for the upcoming event. Side benefits for the TS-480HX is I am going to pair it up the new HiQ 5/160 mobile antenna purchase and have lots of fun this winter with HF mobile. Now it looks like I need to get a laptop for mobile ALE eh ??? Hi Hi Hey, good luck to all this weekend. I am looking forward to it! 73 from Bill - WD8ARZ South Bend, Indiana Need a Digital mode QSO?

Just emailed the Flex-Radio technical support guy to see if V4.03 is the problem. He didn't mention it in the past, and I know that there's a document on setting up V4.03 with PowerSDR.

[digitalradio] Digital Voice: Some thoughts after one week.
I have been QRV on digital voice ,using WinDRM, and thought I would offer some rookie/newbie random thoughts. 1. This mode's performance may appear counter-intuitive for most digital mode operators. By that I mean, we associate digital modes like PSK31, Olivia, MT63, etc, with the ability to communicate under weak signal conditions. To be able to communicate when SSB analog voice signals are not reliable. It is the opposite with Digital Voice , as manifested in WinDRM. Perfectly copyable CW and traditional SSB voice signals do not translate in to enough signal to maintain the digital voice transmissions. e.g. my analog QSO today with Gerhard OE3GBB was about a 449 RST. That is; Readable with practically no difficulty, Fair signals . However, I had to focus my brain quite a bit to pick his voice out between the QRM. When we switched to DV, the audio was stunning in quality (better than FM on 2M) but I only copied about 40% of what he sent, the rest was just silence. So, I am not sure what use this communication method has if we need good signals rather than fair or weak signals. If one can copy a person fair to well with SSB analog, why do we need to switch to DV voice? 2. The software (WinDRM) is very well designed and fairly easy to figure out. The ability to have the software switch Mic/Line In settings in the sound mixer is very useful. The waterfall and other tuning display indicators are extremely well thought out. 3. There is something odd about copying HF signals with good audio fidelity. My old ham brain is so used to Donald Duck under water SSB audio that hearing a DV signal does not sound like real radio. It IS real radio because it is sent/received via radio waves , but it feels like you are on Echolink , IRLP, or Skype!. 4. It is exiting to be on air with just the few that are active. If you expect to hear LOTS of DRM signals, you'll be disappointed. Activity is less than Hell or MT63! 5. WinDRM shows that DV can be done well without expensive outboard hardware devices (AOR). It works with a fairly low CPU PC. I think we are in the Betamax-VHS era for amateur radio digital voice, with several incompatible DV modes. Andy K3UK Need a Digital mode QSO?

RE: [digitalradio] Digital Voice: Some thoughts after one week.
Title: Message Just my two cents worth, Andy. I'm even newer at it than you, but today was a real poor day to be trying DV. With a SSB contester parked on 14.236 all afternoon, I had no chance at all to copy OE3GBB, or anyone else. I caught enough of the signal to get his call, but that was it. I'm trying to determine how to get the inbound audio from WinDRM out to either the speaker on the PC, or the headset I'm using. I seem to be able to transmit okay so far, but it's an "alligator setup" - all mouth and no ears! -Original Message-From: digitalradio@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Andrew O'BrienSent: Sunday, October 08, 2006 2:14 PMTo: digitalradio@yahoogroups.comSubject: [digitalradio] Digital Voice: Some thoughts after one week.

Andrew O'Brien wrote: I have been QRV on digital voice ,using WinDRM, and thought I would offer some rookie/newbie random thoughts. I think that you may be looking at this from the wrong angle, Andrew, DRM is intended as a very high quality mode, capable of very high quality reproduction and, just like in FM broadcast terms, this has its limitations. You need high s/n+n ratios and the associated bandwidth to go with it. If Amateur Radio were just about being able to work ultra-DX then many modes and bands would never have been developed. SSTV, especially Digital SSTV, also requires good signals and wide (in comparison to CW/SSB or even WSJT modes) bandwidth. Fast Scan TV on 23cm requires even more bandwidth. However, people do use wideband modes and enjoy the challenge that these modes bring. If you use some of the very high microwave bands a few miles is an achievement. That doesn't mean that quite long distances are not able to be worked, given the right conditions and a good deal of application, but you are not going to get DXCC of 10GHz, unless you go to using moon bounce, which is possible, but not easy... If you want to work the world, quickly, then DRM, Fast Scan TV and other specialist modes are not going to be the way to go. However, if you enjoy a challenge and find that every contact completed, whether that contact is over a distance of 1 mile or 1000 miles, is an enjoyable proof that it can be done, then stick with it.

[digitalradio] ALE On The Air Week 13-23 Oct (Automatic Link Establishment QSO Party)
==HFLINK SPECIAL BULLETIN== ALE On-The-Air Week 13-23 October AOTAW-2006 The Automatic Link Establishment International QSO Party START: 0001 UTC 13 October 2006 END: 2359 UTC 23 October 2006 HFLINK is sponsoring this new International Amateur Radio event. All ham radio operators worldwide are invited to participate in 10 days of amateur radio HF-ALE Automatic Link Establishment activity on the air. AOTAW is an open operating event for hams to explore ALE communications and equipment. The experience gained by operator participation is useful for HF emergency and disaster relief communications. There are now hundreds of amateur radio operators worldwide with ALE stations. The AOTAW gives operators a chance to exercise ALE transceivers, antennas, software, systems, and operating procedures. ALE OPERATOR CERTIFICATE for AOTAW2006 HFLINK issues a unique ALE Operator Certificate to operators who participate in AOTAW. To qualify for an ALE Operator Certificate, the operator must initiate and complete at least 5 QSOs through Automatic Link Establishment with other ALE operators. The ALE link must then be followed by communication either by voice or texting in any mode. Additional certificate endorsements are issued by HFLINK for operators who link with 25 stations or more. LOGS: To qualify for a certificate, please send a Date/Callsign/Frequency log of your ALE QSOs by 31DEC2006 via email to: aotaw2006@ yahoo.com The certificate will be returned via direct email. OPERATING STANDARDS FOR AOTAW All operators are reminded to be courteous and operate within the recognised Amateur Radio ALE channels and standards. Please remember, AOTAW is not a contest, there is no score. AOTAW is intended to provide a way for more operators to gain valuable practical knowledge and expertise in the operation of an Amateur Radio ALE station. CQ - NETCALLS, ALLCALLS, ANYCALLS 1. NETCALLS: HFL net or QRZ net may be used as the general CQ calls for the event. 2. ALLCALL: SHOULD NOT BE USED in AOTAW. A QSO started by an ALLCALL does not qualify as a valid ALE link. 3. ANYCALL: Anycalls may be used. But remember, many ALE stations are not programmed to respond to Anycalls. RECOMMENDED ALE QSO PROCEDURE AND MODES 1. Call CQ: Transmit a CALL NETCALL to either the HFL net or the QRZ net. Wait at least 1 minute for responses. 2. Call a station: Transmit an INDIVIDUAL CALL to the station. It may be necessary to first add the station's callsign (address) to your ALE address list. 3. Upon linking on a VOICE channel, then use USB Voice for the QSO. 4. Upon linking on a DIGITAL channel, then send a short AMD message with the linked station. 5. When QSO is completed, transmit the CLEAR LINK signal. STANDARDS FOR DIGITAL TEXT QSO After initial ALE link on a DIGITAL channel, use the universal short text message for ALE, called AMD. An AMD message request to the other operator can ask for other digital text keyboarding, such as: ALE AMD: is the universal ALE text message system. DTM ARQ: only by stations who are using PC-ALE or MARS-ALE software. PSK31: (1500Hz centre) ask operator first via AMD. Olivia: (1500Hz centre, 500/16) ask operator first via AMD. CW: ask operator first via AMD. ABOUT AOTAW Amateur operators who use ALE for government and non-governmental organisations may be especially interested in participation, for it provides more chance to work with ALE linking and greater understanding of the system. It is a chance for operators to explore the various operational aspects of ALE that may not be utilised otherwise in a more structured organisation ALE network. The 10 days of AOTAW enables operators to participate as they can, for any amount of time in the event, and to experience ALE operation under various ionospheric propagation conditions.

I copied Rick with a SNR of 7.1 on 7166 but no DV.

Re: [digitalradio] Re: QRV DV 7166 and 3733
Well I was able to print out Andy's fairly long message on 7166 LSB. Also, could copy message from Tony, KT2Q. Also, worked Tony and KB3MOW on LSB voice, but no go on DV. So the text messages don't seem to require all that much signal. Maybe 3 to 5 db above the noise? From what I can tell, longer distance evening 75 meters would not work most of the year unless you had rock crusher signals due to the QRN. Even 40 would be marginal. I can see that the higher frequencies would be best for this kind of mode since they tend to have much lower atmospheric noise to overcome. However, unless you are within ground wave, it will only work with stations in the skip zone. And that assumes the particular band is open outside of the ground wave pattern. 73, Rick, KV9U Tony wrote: OK Andy LSB -- calling you now on 7166.0 It's 00:02z Tony KT2Q - Original Message - From: Andrew O'Brien [EMAIL PROTECTED] To: digitalradio@yahoogroups.com Sent: Sunday, October 08, 2006 7:58 PM Subject: [digitalradio] Re: QRV DV 7166 and 3733 Make that L S B . --- In digitalradio@yahoogroups.com, Andrew O'Brien [EMAIL PROTECTED] wrote: I will alternate sending auto cq file via WinDRM at 00,15,30, 45 minutes past the hour from 00 to 0200 UTC tonight October 9 (UTC).

Re: [digitalradio] Re: 80M DV freq
How do you set the mike gain? I am using a standard el cheapo electret type mike plugged into the computer mike input, but can only guess where the level should be. I wish we would pick one frequency and sideband for each band for basic contacts that we could monitor. This is what the SSTV folks do and if they need more space they can just move up 3 KHz or so. I seem to be getting RF into my ICOM 756 Pro 2 rig when I am using my dipole on 75 meters so can not operate on that band at this time, but could listen. I can run 50 watts on 40 meters without triggering the ALC. Should we run this mode similar to other digital modes where you adjust the audio input levels to be just low enough with a given RF drive setting to not trigger ALC? 73, Rick, KV9U expeditionradio wrote: --- In digitalradio@yahoogroups.com, Dave Corio [EMAIL PROTECTED] wrote: Unfortunately, that still puts it out of reach of us Generals.

[digitalradio] 40M DV bandplan
Yep, I should have thought about the folks that are restricted to General class, I used to hate it when people did that to me! So, I'm going to try 7238 which seems clear of broadcast band QRM. Rick's point about SNR on a band like 80M at night is well taken, so I'll give up on 80M but will try 7238 until 0200 tonight. By the way, as Rick suggests the text message transmitted in the ACQ.txt filerequire less of an SNR than DV. I made a .txt file (called r.txt) for returning to stations that I hear after my ACQ. I have it up and running so that I can simply change the call sign and SNR report, save it, and transmit it as a picture. I have included it below so that you can steal and personalize. Andy K3UK -- KV9U , Good evening . Your report is SNR=7.1 Name here is Andy and the location if Fredonia New York (FN02hk) about 45 miles South West of Buffalo, NY.. Running 100 watts here in to a dipole. So, how copy ? If SNR is above a 9.0, we may want to switch to Digital Voice. Back to you de Andy K3UK. Andy K3UK __._,_.___ Need a Digital mode QSO?

Re: [digitalradio] Re: 80M DV freq
I am using just the computer's built in sound card. I am not sure if it is possible to make this work when switching back and forth since wouldn't you have to switch the recording input from line to mike when going from receive to transmit? Not been able to get any mike response so have to be doing something wrong. Not hearing a peep out of the computer speakers either. So maybe I am doing this completely wrong. I am picking up KT2Q, Tony's text message with around 5 db S/N on 7238. The signal is about S5 on my 756 Pro 2 meter which means I am receiving about a 12 uV signal which would be very useable for SSB and way more than necessary for many of the regular digital modes. Not sure how useful DV will be and even then I suspect the main niche would be as a substitute for ESSB operation due to the expected coming restriction of bandwidths on HF frequencies. On the other hand, based on the fact that the text messaging seems pretty good, and very fast and accurate, why wouldn't this type of mode work as a higher speed version of a SCAMP type ARQ digital mode? With the slowest robust mode, what kind of S/N ratio can it work down to for just sending data? 73, Rick, KV9U Dave Corio wrote: I believe you put the program into TX Voice and adjust your mic input to get a good green (not red) waveform on the WinDRM window.

Tony KT2Q wrote: The nighttime QRN on 40 meters is still high so DV is hard to do on this band with S-9 static crashes unless signals are well above the noise. Hi Tony, The HFpack DV group has very good luck using the AOR units on 40 meters. Most of the operation is single-hop NVIS around the western USA in the two hours just before local sunset. The S/N is very good, even for QRP stations, and there is very little broadcast QRM in The West at that time of day. The same is true on 80 meters, except the best times are shortly after local sunset and in the morning before 10AM local time. Later at night, when the bands go long, the tropical lightning storms make the S/N worse. Sadly, we can't use DV on 60 meters... that would be a great band for DV.

[digitalradio] Re: Digital Voice: Some thoughts after one week.
--- In digitalradio@yahoogroups.com, Andrew O'Brien [EMAIL PROTECTED] wrote: I have been QRV on digital voice ,using WinDRM, and thought I would offer some rookie/newbie random thoughts. 1. This mode's performance may appear counter-intuitive for most digital mode operators. By that I mean, we associate digital modes like PSK31, Olivia, MT63, etc, with the ability to communicate under weak signal conditions. To be able to communicate when SSB analog voice signals are not reliable. It is the opposite with Digital Voice , as manifested in WinDRM. Perfectly copyable CW and traditional SSB voice signals do not translate in to enough signal to maintain the digital voice transmissions. e.g. my analog QSO today with Gerhard OE3GBB was about a 449 RST. That is; Readable with practically no difficulty, Fair signals . However, I had to focus my brain quite a bit to pick his voice out between the QRM. When we switched to DV, the audio was stunning in quality (better than FM on 2M) but I only copied about 40% of what he sent, the rest was just silence. So, I am not sure what use this communication method has if we need good signals rather than fair or weak signals. If one can copy a person fair to well with SSB analog, why do we need to switch to DV voice? 2. The software (WinDRM) is very well designed and fairly easy to figure out. The ability to have the software switch Mic/Line In settings in the sound mixer is very useful. The waterfall and other tuning display indicators are extremely well thought out. 3. There is something odd about copying HF signals with good audio fidelity. My old ham brain is so used to Donald Duck under water SSB audio that hearing a DV signal does not sound like real radio. It IS real radio because it is sent/received via radio waves , but it feels like you are on Echolink , IRLP, or Skype!. 4. It is exiting to be on air with just the few that are active. If you expect to hear LOTS of DRM signals, you'll be disappointed. Activity is less than Hell or MT63! 5. WinDRM shows that DV can be done well without expensive outboard hardware devices (AOR). It works with a fairly low CPU PC. I think we are in the Betamax-VHS era for amateur radio digital voice, with several incompatible DV modes. Andy K3UK Andy, I've had some of the same thoughts. Much of the attraction of Ham radio to a lot of people is the ability to work long distances. CW still lives and PSK31 has been widely accepted because of this. It was quite a thrill when I worked someone in Russia with PSK31 who was using a homebrew rig with 5 watts output. PSK31 has opened Ham radio to a lot of people who can't put up a big antenna or run high power. When I first tried analog SSTV a few months ago I thought about how primitive it was compared to digital communications today. However when I tried HamPal it was very disappointing to find out how difficult it was to receive a picture even with an S9 signal. The picture quality is stunning but the success rate is so low that it will never replace analog SSTV. I had hoped that DV would be able to improve the quality of communication over analog voice in conditions when analog voice was marginal. It seems that if we could trade some of the voice quality for better weak signal performance it would be much more attractive to many hams. With SSTV, weak signal performance could easily be improved by reducing picture resolution and reducing the data rate. That is a little more difficult to do with voice since voice communications must be in real time - we can't just slow the data rate down to fit the channel conditions. I work in cellular communications and know that good voice quality can be maintained with a data rate of 8k bps. It seems reasonable that useable voice quality can be produced with half that data rate. Are there any communications engineers in this group that can give us some idea whether a useable quality digitized voice can be sent over a 2.5 KHz wide HF channel with SNR comparable to or less than what is required for analog voice?

Hi Bonnie, The HFpack DV group has very good luck using the AOR units on 40 meters. Most of the operation is single-hop NVIS around the western USA in the two hours just before local sunset. Understand completely. It's amazing what you can do with low noise and a little power; especially single-hop NVIS. Would love to hear a recording of an HFPack AOR decode!

Hi Tony, The HFpack DV group has very good luck using the AOR units on 40 meters. Most of the operation is single-hop NVIS around the western USA in the two hours just before local sunset. The S/N is very good, even for QRP stations, and there is very little broadcast QRM in The West at that time of day. The same is true on 80 meters, except the best times are shortly after local sunset and in the morning before 10AM local time. Later at night, when the bands go long, the tropical lightning storms make the S/N worse. Sadly, we can't use DV on 60 meters... that would be a great band for DV. I can hear commercial and government stations using DV on 5MHz every day. Bonnie KQ6XA Need a Digital mode QSO?
