[digitalradio] Yet Another New Solar Cycle 24 Sunspot Group
Posted Sunday November 15, 2009 at http://www.wcflunatall.com/nz4o4.htm Yesterday yet another solar cycle 24 sunspot group emerged, this time in the NE quadrant of the Sun near N29E35. As of yet it has not received a number by SIDC Belgium or NOAA/SWPC. If numbered by NOAA/SWPC it would receive #11031. This new sunspot group pushed the solar flux index (SFI) to 75.9 yesterday and could push the SFI above 80 in coming days. This would raise the maximum usable frequency (MUF) of the F layer high enough to improve propagation conditions on 20, 17 and 15 meters. Under the very old method of counting sunspots SIDC Belgium gave the sunspot group a number of 11. But in reality only one simple sunspot actually emerged. The solar cycle 24 sunspot group that emerged on Friday November 13, 2009 that received SIDC Belgium Catania #25 and located in the SW quadrant of the Sun has faded, with it's remnant Plage currently setting around the west limb of the Sun. It did not receive #11031 by NOAA/SWPC. Also yesterday old solar cycle 24 sunspot group #11029 rose above the east limb of the Sun but is only a large Plage with no sunspots. Last month #11029 made it's debut as the largest and most active sunspot group in fledgling solar cycle 24. 73 GUD DX, Thomas F.

I'll take a listen for you Steinar, However, the frequency that you have chosen is not one of the ones authorised in the UK, so I will not be able to reply of course. I wonder why you chose 5.350MHz? I believe that 5.290MHz MHz is authorised in Norway as I have heard LA stations having SSB contacts when I have been monitoring GB3RAL and the other UK beacons. There is some WSPR activity below the CW beacons and I am seeing G0KTN on 5.288.685MHz and PA3ABK is monitoring as well, according to the WSPRnet map at http://wsprnet.org/drupal/wsprnet/map My own transmissions using WSPR in MEPT_JT mode are currently running on 5.288.700MHz. I'll shut WSPR down in a moment or two and will then run WSJT7 to listen on 5.350MHz for JT65A. Dave (G0DJA)

Re: [digitalradio] JT65A Beacon on 60m
Hi Dave In Norway the band 5260 - 5410 kHz is now open for general Amateur Radio use. The band is not channelized. The allocation is secondary and power is limited to 100 watts. To avoid conflicts with other country's channels the Norwegian Radio Relay League (NRRL) has decided that we shall use: CW: 5305 - 5315 kHz QRP: 5335 kHz All mode: 5335 - 5340 kHz Digital: 5350 - 5360 kHz USB: 5375 - 5394 kHz Norwegian HAM's will only use the channels in QSO with HAM's outside Norway. 73 de LA5VNA Steinar http://folk.uio.no/tomvs/la4ln/Worldwide%2060%20m%20frequency%20chart_v8.pdf Dave Ackrill wrote: Steinar Aanesland wrote: Hi all I am running a 5W JT65A beacon at 5350 Khz + 1270Hz USB this evening.

Re: [digitalradio] JT65A Beacon on 60m
Hello Steinar, I left my transceiver on duty and that is what I got (QTH near Paris). I used Multipsk without KVASD (to avoid false detections) so the minimum S/N was -24 dB (hard decision) instead of -26 dB (soft decision). Your signal was very weak (-20 to -25 dB) but still decodable in JT65. 73 Patrick Here it is: 12:20 4 -22 3 -0018 LA5VNA/B 12:22 9 -20 3 -0018 LA5VNA/B 12:44 4 -22 4 -0015 LA5VNA/B 12:46 5 -23 4 -0015 LA5VNA/B 13:16 5 -24 1 -0012 LA5VNA/B 13:34 3 -23 3 -0012 LA5VNA/B 13:36 5 -21 3 -0012 LA5VNA/B 13:40 4 -22 3 -0012 LA5VNA/B 13:48 1 -23 3 -0012 LA5VNA/B 13:50 6 -22 3 -0012 LA5VNA/B 13:52 5 -23 3 -0012 LA5VNA/B 13:54 3 -24 3 -0012 LA5VNA/B 13:58 5 -22 3 -0012 LA5VNA/B 14:02 6 -21 4 -0012 LA5VNA/B 14:04 3 -23 4 -0012 LA5VNA/B 14:06 4 -23 4 -0012 LA5VNA/B 14:08 9 -23 4 -0012 LA5VNA/B 14:10 6 -23 4 -0012 LA5VNA/B 14:12 6 -21 4 -0012 LA5VNA/B 14:14 6 -20 4 -0012 LA5VNA/B 14:16 6 -20 4 -0012 LA5VNA/B 14:18 8 -19 5 -0012 LA5VNA/B 14:20 3 -24 4 -0010 LA5VNA/B 14:22 7 -23 5 -0012 LA5VNA/B 14:24 5 -24 5 -0012 LA5VNA/B 14:26 7 -23 5 -0012 LA5VNA/B 14:30 4 -22 5 -0010 LA5VNA/B 14:32 9 -22 5 -0010 LA5VNA/B 14:38 4 -24 5 -0012 LA5VNA/B 14:40 4 -25 5 -0012 LA5VNA/B 14:42 3 -22 5 -0010 LA5VNA/B 14:44 3 -21 6 -0012 LA5VNA/B 14:54 5 -22 6 -0012 LA5VNA/B 14:56 7 -24 6 -0011 LA5VNA/B 14:58 3 -22 6 -0010 LA5VNA/B 15:00 3 -20 6 -0010 LA5VNA/B 15:02 4 -24 6 -0011 LA5VNA/B 15:08 5 -24 6 -0011 LA5VNA/B 15:10 3 -22 6 -0010 LA5VNA/B 15:14 5 -23 6 -0010 LA5VNA/B 15:16 4 -23 7 -0010 LA5VNA/B 15:26 6 -21 7 -0010 LA5VNA/B 15:28 4 -26 7 -0010 LA5VNA/B 15:30 7 -22 7 -0010 LA5VNA/B 15:34 4 -23 8 -0010 LA5VNA/B 15:36 10 -20 8 -0010 LA5VNA/B 15:38 7 -25 8 -0010 LA5VNA/B 15:40 9 -22 8 -0010 LA5VNA/B 15:46 5 -20 8 -0010 LA5VNA/B 15:48 5 -20 9 -0010 LA5VNA/B 15:50 4 -20 9 -0010 LA5VNA/B - Original Message - From: Dave Ackrill dave.g0...@tiscali.co.uk To: digitalradio@yahoogroups.com Sent: Sunday, November 15, 2009 5:15 PM Subject: Re: [digitalradio] JT65A Beacon on 60m Steinar Aanesland wrote: Hi all I am running a 5W JT65A beacon at 5350 Khz + 1270Hz USB this evening.

[digitalradio] Digital on 2M FM: Audio settings ?
Hmmm. Well I thought it would be simple enough to transmit digital modes on 2M FM but one issue I just ran in to is the ALC is very high and my usual method of lowering it has no effect. I also lowered the mic gain but that had no impact. Something simple I am not taking in to account when using FM ? Andy K3UK

Re: [digitalradio] Digital on 2M FM: Audio settings ?
I would guess, that setting the audio on the low side would be preferable. In the packet days, we used to set out deviation to 3.0 - 3.5 KHz as it assured us of never over deviating. As long as we got at least 10 dB quieting in the rx'er, we experienced fewer retries. philw de ka1gmn On Sun, Nov 15, 2009 at 7:15 PM, Andy obrien k3uka...@gmail.com wrote: That's what I am guessing...not much of an FM operator On Sun, Nov 15, 2009 at 8:12 PM, Phil Williams ka1...@gmail.com wrote: Doesn't the ALC behave differenty when runnning FM? philw de ka1gmn On Sun, Nov 15, 2009 at 6:55 PM, Andy obrien k3uka...@gmail.com wrote: Hmmm.

RE: [digitalradio] Digital on 2M FM: Audio settings ?
The carrier has a constant level on FM, so the ALC doesn't mean much. If you want to monitor the drive level you would need to monitor the deviation. If you could monitor the transmitter, that would probably work.

Re: [digitalradio] Digital on 2M FM: Audio settings ?
Andy, I believe you have a Kenwood TS2K(?). If so, there is a way to control the digital mode audio level on FM. If you're feeding the audio through the microphone connector, menu 41 has a low, medium and high setting. If your using the 13 pin DIN plug, the audio input can be adjusted via menu # 50. Tony -K2MO
