Re: Time to end the digital charade on 60M ? #JT65

That just brings up the issue of equipment frequency accuracy.  Not everyone has even 100 hz accuracy which is about the range one can copy an off frequency USB voice. . . And the limit for out of band signals (harmonics…splatter… everything) is 25 mW. for newer equipment. So I really wouldn’t expect everyone to net their transmissions unless they have a GPS disciplined reference or a working trusted reference.

HDSDR Homepage

By SDRPlay

The folks at HDSDR have released Version 2.75 – see www.hdsdr.de (This is compatible with both the RSP1 and RSP2)

The new version has the following features:

– more recording options
– support for 8bit sampling format – ideal for RTLSDR, halving RF recording size
– display level / clipping for RF and AF
– additive noise generator for hiding aliases
– Highpass Filter for AM/FM deactivatable – useful for slow digimodes
– configurable gain for I/Q output – useful for digimode decoding weak signals of SDRs with >16 Bit dynamic range
– Uniform “Calibration” dialog for Frequency/S-Meter/DC Removal/Channel Skew
– “Custom color palette” to customize colors of Waterfall/Spectrum and some more
– output soundcard no longer necessary (e.g. for recording or monitoring)
– support for 8k display resolution (7680×4320)
– some new keyboard shortcuts (see )
– extended ExtIO capabilities
– experimental transmit capability through ExtIO API interface
– many fixes and improvements

Meanwhile, Simon Brown is on track to release a new version of SDR Console V3 preview which will support the RSP2 early next week (January 9th/10th)

Cloud SDR have informed us that they have just released two programmes compatible with our SDRPlay devices :

The Cloud-SDR free client, a windows + Linux (to be released soon) client able to run locally SDRPlay RSP1 or RSP2 SDRs,
The Cloud-SDR streaming server (codenamed SDRNode) , a windows + Linux (to be released soon) multi-user configurable streaming server.
SDRNode is a commercial software product but an evaluation version is already available. Both software programmes can be downloaded from their store after registration.
Source code for the drivers are already released as open source software through the Cloud-SDR GitHub repository: https://github.com/cloud-sdr

ARRL - FCC Turns down 2 petitions

main@digitalradio.groups.io Integration <main@...>
 

Timeline Photos

By ARRL - the National Association for Amateur Radio

The #FCC has turned down two petitions filed in 2016, each seeking similar changes in the Part 97 Amateur Service rules. James Edwin Whedbee, N0ECN, of Gladstone, Missouri, had asked the Commission to amend the rules to reduce the number of Amateur Radio operator classes to Technician, General, and Amateur Extra by merging remaining Novice class licensees into the Technician class and all Advanced class licensees into the Amateur Extra class. In a somewhat related petition, Jeffrey H. Siegell, WB2YRL, of Burke, Virginia, had requested that the FCC grant Advanced class license holders Morse code operating privileges equivalent to those enjoyed by Amateur Extra class licensees. #ARRL #HamRadio http://ow.ly/kh5K307Kprd


60-meter band effective at 0000 EST on March 5, 2012

FYI
===
In November 2011, the Federal Communications Commission issued a Report and Order that substantially expanded Amateur Radio privileges on the 60-meter band. The new privileges will take effect at 0000 EST on March 5, 2012. The ARRL offers the following as a set of Recommended Operating Practices for these rules changes:

Amateurs are permitted to operate on five frequency channels, each having an effective bandwidth of 2.8 kHz.

http://www.arrl.org/60m-channel-allocation

The FCC grant followed a period of experimental operation on 5 MHz under the WA2XSY Part 5 license granted to ARRL. The channelized scheme is similar to the 5-MHz experimental operation under way in the United Kingdom.

The FCC  changed one frequency effective March 5, 2012 and now grants amateurs access to channels centered on 5332, 5348, 5358.5, 5373, and 5405 kHz. The last channel is common to the UK amateur 5-MHz experimental band plan.

Note: All frequencies / channels for voice are to use Upper Side Band

Jim,


Thanks for the references.  Indeed you are correct, the FCC said "may".  However, the first sentence is more restrictive I believe, stating that stations "may transmit ONLY on the five CENTER frequencies".  IDK, IANAL.

(h) 60 m band: (1) In the 5330.5-5406.4 kHz band (60 m band), amateur stationsmay transmit only on the five center frequencies specified in the table below. In order to meet this requirement, control operators of stations transmitting phone, data, and RTTY emissions (emission designators 2K80J3E, 2K80J2D, and 60H0J2B, respectively) may set the carrier frequency 1.5 kHz below the center frequency as specified in the table below.

It says "may" and not "shall" and there is a difference between "carrier" (set to 1.5khz below frequency and the modulation side bands. Bandwidth number for digital and RTTY modes is 2 khz for the "B" and "D" tho and not 2.8khz.  PSK31 specification leaves me a bit puzzled as it calls for the PSK31 and CW to be on the center of the channel. For everything else with a "published" mode, keep within the channel and avoid any "primary" user.

APRS Is An Active Digital Activity Too 01/05/17

WD8ARZ
 

There is still a lot of APRS being used too. Not just for tracking, but also for weather alerts and receiving local event information from base stations that transmit it. Have met a number of hams when on trips due to them calling me on the frequency listed in my APRS beacons that show up on their map display. My true location is off due to my truncating the last two digits of the Lat and Long data ......... helps prevent theft when I am out of the vehicle for a bit.
