Radio: it's not just a hobby, it's a way of life

Current Operating Frequency and Mode

OFF AIR for storms - just one more night - should be QRV Saturday night!

‘Good CW night’ on 630-meters as terrestrial and geomagnetic conditions continue at quiet levels; NO3M makes a push for QSO activity with Europe – who will step up and make it reality?; Noise improving in Oceania but now noisy in KH6 and JA; W5EST presents: ”A Slow Voice Phone Mode: What Emission Type?”

– Posted in: 630 Meter Daily Reports, 630 Meters

The details for November 1, 2016 can be viewed here.

The UTC amateur registration database is here.

HERE are a few mode-specific comments addressing where modes are located now and probably where they are best placed in the future

Curious about who is on the air making two-way QSO’s? Roger, VE7VV, is maintaining this list. If you complete QSO’s, be sure to let us know so he can add you to the active operator list.

It was mostly quiet in North America during the evening.  Overnight storms unexpectedly developed in my area of North Texas around 0500z and I had to scramble to get the station secured.    Strong storms were present over northern Japan and Oceania continues to experience storms but a few stations were active on Australia and New Zealand, making the best of a bad situation.  VK4YB expects improvements in the coming days.  K9FD on Molokai reported very high QRN from storms near the island.  Merv indicated that he would remain on the air as long as it was safe to do so.

The following stations provided reports of their two-way QSO’s as well as any additional activity that might have occurred during this session (this is not necessarily a complete list – only what was reported!):

Eric, NO3M, reported that it was a good CW night and he was not wrong.  He completed QSO’s with W1TAG and W3LPL for first time QSO’s followed by repeat QSO’s with K8TV, K4EJQ, K1RGO, and N9EGT.  Eric was also hearing W0RW but  he was unable to get Paul’s attention.  Eric also called CQ on JT9 at UK sunrise, listening in that direction for calls.  He posted on the RSGB-LF reflector so hopefully in coming days he can stir up some business.  This morning Eric reported VK4YB’s CQ on JT9 at 1136z at -27 dB S/N.  Eric indicated that he called Roger but was not heard.

Frank, W3LPL, completed CW QSO’s with K1RGO and NO3M.  Frank was heard briefly on peaks here but I suspect we will need a morning QSO for the most stable band conditions at least until we get deep into Winter.

Wayne, K9SLQ, reported a good night working two new states and a Canadian station.  He completed a CW QSO with K4EJQ and JT9 QSO’s with KC4SIT, W7IUV, VE3CIQ and AA1A.

Larry, W7IUV, completed  evening JT9 QSO’s with ZF1EJ and K9SLQ, both of which were new for Larry.  This morning he  worked K2BLA, who was worked for the second time on JT9.  Larry indicated that he heard a bit of CW but did not work anyone.  He is now at 28 initial QSO’s and running out of stations.  As W7IUV/W, Larry reported WSPR from VK4YB.

David, N1DAY, completed a JT9 QSO with VE3CIQ.  Overnight on WSPR he reported thirteen stations and received reports from 64 unique stations.

Neil, W0YSE, completed a JT9 QSO with VE7VV with signal levels ranging between -11 dB and -23 dB over just a few minutes of the QSO so QSB remains very high.  Overnight on WSPR Neil received reports from 37 unique stations, including new station, WB8SKP.   The following stations represent Neil’s best DX:

Al, K2BLA, completed a JT9 QSO with VE7SL, which was a new station and best DX for Al to date.  He also completed a JT9 QSO with W7IUV. Al indicates that this was a low noise session.  During his morning WSPR session, he reported eleven stations and was reported by 48 unique stations,  twelve of which were over 3000km in distance.  He also shared two-way WSPR reports with K9FD.

Activity at KB5NJD was limited to the evening and I spent a lot of time listening and documenting activity.  I completed a quick CW QSO with K4EJQ who was a good RST 589 at 0037z.  He reported me at RST 449.  It was a bit early for my signal but enjoyable nonetheless.  I also briefly heard W3LPL on CW on a peak and suspect we will have best success with a morning QSO.  Its good to see so much CW activity on the band.  I was QRT this morning after an unexpected storm arrived around local midnight and I had to quickly secure the station.

Paul, W0RW, called CQ on CW just moments after I QRT’ed for the night and was reported by NO3M but Paul never heard Eric.  Paul received email reports from Steve, AA7U, located in Arizona and Mark, KU7Z, located in Utah.  Neither station is able to transmit at this time but hopefully that will be resolved shortly.

Hideo, JH3XCU, submitted this summary of DX->JA Spots per Day from September 1, 2017  to  October 31, 2017.

Hideo also provided this link detailing DX -> JA decode totals and DX -> JA S/N peaks for the session, as reported on the Japanese language 472 kHz website.

Roger, VK4YB, indicated that “QRN was moderate, but should get better over next few days. Perhaps the chance of 2 way JT9 QSOs. Tonight JT9 heard by 7, best Eric, NO3M, WSPR heard by 21, best Ken, SWL/K9.”  Roger received WSPR reports from KL7L, KR6LA, KR7O, SWL/K9, VE6JY, VE6XH, W6SFH and W7IUV/W. He shared two-way reports with K9FD and VE7CA.

Ken, SWL/K9, reported that his overnight WSPR listen session resulted in 24 reports of K9FD, best at -24db S/N and one report for VK4YB at -28db S/N.

Robert, KR7O, indicated that he decoded VK4YB for the first time beginning at 1142Z at -22 dB S/N followed by a later report down to -20 dB S/N.  In all, Robert decoded Roger thirteen times between 1142 and 1248z.  He also reported ZF1EJ five times, best at -26 dB S/N.

Ken, K5DNL, reported that he is testing a small amplifier at 42-watts TPO in a transmit-only capacity until he can complete the receive relay.  On WSPR overnight, Ken received reports from 83 unique stations including EA8BFK, K9FD and ZF1EJ.

Rick, W7RNB, operated WSPR only during this session, reporting eight stations and receiving reports from 35 unique stations.  Rick’s unique report details can be viewed here.

Dave, N4DB, reported that he decoded fifteen WSPR stations including his best DX, ZF1EJ.  Dave indicated that he decoded no Pacific Northwest stations during this session.

Doug, K4LY, reported “Quiet and good high latitude prop to EU. Just repositioned my amplified KAZ to favor NE and decoded first TA of season, powerhouse F5WK plus 20 others inc K9FD. + W0YSE.”

Mike, WA3TTS, reported that he decoded twenty WSPR stations including G8HUH and F5WK for his first trans-Atlantic reports of the season.  He also submitted the following highlights of his best DX for the session:

“K9FD   27 spots, -18 best @ 0734, min -25 @ 0906 & 1028, fairly even distribution.
F5WK  11 spots,  -24 best @ 0540, min -30 @ 0516 & 0534.
G8HUH  4 spots, -23 best @ 0550, min -25 @ 0600.
W0YSE  3 spots,  -25 best @ 0718, min -29 @ 1044.
W7RNB 6 spots, -24 best @ 1030,  min -27 @ 1116.
ZJ1EJ    28 spots, -10 best @ 0732, min -23 @ 0550.”

Eden, ZF1EJ, completed a very nice transcontinental JT9 QSO with Larry, W7IUV (screen capture previously presented).  Eden was also active this morning and reported VE7SL at -12 dB S/N but I don’t believe that they completed another QSO.  On WSPR overnight, Eden reported nine stations and he received reports from 46 unique stations.  He shared two-way reports with K9FD.

ZF1EJ session WSPR activity


Laurence, KL7L, reported a number of JT9 signals overnight (screen capture posted earlier) and called CQ for a bit this morning on the approach to sunrise.  He and W7IUV are trying to sync up the openings so that they can complete a QSO.  As Laurence put it, they were “two ships passing in the night” this morning as the ionic fog continues to impact band conditions at high latitudes.  Overnight with WSPR, Laurence reported eight stations including VK4YB and he received reports from sixteen unique stations  including JA1PKG/2 so there has been some improvements. He shared two-way WSPR reports with K9FD, KR6LA, VE7CA, W0YSE and W7RNB.  Select DX report details can be viewed here.

KL7L session WSPR activity


Merv, K9FD, reported high noise from nearby storms so he remained on WSPR through the night, providing reports for sixteen stations. He shared two-way WSPR reports with VK4YB, ZF1EJ and KL7L. Merv received WSPR reports from 53 unique stations including JA1NQI, JA1PKG/2, JH3XCU, VK2XGJ, VK3ALZ, VK7TW, KL7KY and ZL2AFP.  DX report details can be viewed here.

Jim, W5EST, presents, “A Slow Voice Phone Mode: What Emission Type?”:

“In the year 2000, a slow voice mode of a DK8KW-DF6NM experiment slowed down a human speech frequency band 300Hz-3kHz by a factor of 10 to a frequency band 30-300Hz.  By upconverting to 800Hz +/- 150Hz, one could send via a conventional SSB 630m TX and receive with CW filter bandwidth, on 2200m.  The reception process reversed the steps to recover speech. (Endnote*)

As to permitted voice modes now, use your best informed judgment and stay compliant with all governing radio rules in your country. Today’s post considers whether slow voice SSB is some J,(1,2,3 or X), E phone mode that would be permitted in the USA.

In USA, consult Part 97 at §97.305(c) “Authorized Emission Types” and §97.307(f):  https://www.ecfr.gov/cgi-bin/text-idx?SID=0285acb39fb91da4d46bff0dc2f1067b&mc=true&node=pt47.5.97&rgn=div5

§97.305 Authorized emission types.

…(c) A station may transmit the following emission types on the frequencies indicated, as authorized to the control operator, subject to the standards specified in §97.307(f) of this part.

§97.307 Emission standards.

…(f) The following standards and limitations apply to transmissions on the frequencies specified in §97.305(c) of this part.

(1) No angle-modulated emission may have a modulation index greater than 1 at the highest modulation frequency.

(2) No non-phone emission shall exceed the bandwidth of a communications quality phone emission of the same modulation type. The total bandwidth of an independent sideband emission (having B as the first symbol), or a multiplexed image and phone emission, shall not exceed that of a communications quality A3E emission.

(3) Only a RTTY or data emission using a specified digital code listed in §97.309(a) of this part may be transmitted. The symbol rate must not exceed 300 bauds, or for frequency-shift keying, the frequency shift between mark and space must not exceed 1 kHz.

Regarding the definition of “Phone,” consider USA’s rule 97.3(c)(5).

§97.3::… (c) …Refer to §2.201 of the FCC Rules, Emission, modulation and transmission characteristics, for information on emission type designators….

(5) Phone. Speech and other sound emissions having designators with A, C, D, F, G, H, J or R as the first symbol; 1, 2, 3 or X as the second symbol; E as the third symbol. Also speech emissions having B or F as the first symbol; 7, 8 or 9 as the second symbol; E as the third symbol. MCW for the purpose of performing the station identification procedure, or for providing telegraphy practice interspersed with speech. Incidental tones for the purpose of selective calling or alerting or to control the level of a demodulated signal may also be considered phone.

§2.201Emission, modulation, and transmission characteristics.

The following system of designating emission, modulation, and transmission characteristics shall be employed.

(a) Emissions are designated according to their classification and their necessary bandwidth.

(b) Three symbols are used to describe the basic characteristics of emissions. Emissions are classified and symbolized according to the following characteristics:

     (1) First symbol—type of modulation of the main carrier;

     (2) Second symbol—nature of signal(s) modulating the main carrier;

     (3) Third symbol—type of information to be transmitted.

Note to paragraph (b): Two additional symbols for the classification of emissions may be added for a more complete description of an emission. See Appendix 1, Sub-Section IIB of the ITU Radio Regulations for the specifications of these fourth and fifth symbols. Use of these symbols is not required by the Commission.

(c) First Symbol—types of modulation of the main carrier:…

     (2) Emission in which the main carrier is amplitude-modulated…—Single-sideband, suppressed carrier

(d) Second Symbol—nature of signal(s) modulating the main carrier:…

     (4) A single channel containing analogue information

(e) Third Symbol—type of information to be transmitted:…

     (6) Telephony…

§2.202 Bandwidths.<JH Note: 2.202 tells how to designate bandwidths.>

For ITU emission designators, go to https://www.itu.int/en/history/Pages/RadioRegulationsA.aspx?reg=1.43 (scroll down 2/3 to list of PDFs. Click on PDF of Radio Regulations, edition of 2016 (Volume 2) and scroll to its pp. 4-5.)

       J:  Single-sideband with suppressed carrier

       1:  A single channel containing quantized or digital information without the use of a modulating sub-carrier

       2:  A single channel containing quantized or digital information with the use of a modulating sub-carrier

       3: One channel containing analog information

       X: Cases not otherwise covered

       E: Telephony

For some ITU definitions, see Radio Regulations, edition of 2016 (Volume 1) p.18, 19.

1.123 telephony: A form of telecommunication primarily intended for the exchange of information in the form of speech (CS 1017).

1.140 single-sideband emission: An amplitude modulated emission with one sideband only. 

OK, now for a bit of commentary. Since the slow-voice processed speech is sent single-sideband LSB or USB it’s J,___, E emission. The middle designators 1, 2, 3, and X are all authorized types of emissions (J1E, J2E, J3E, JXE) for 630m and 2200m. So I think the slow voice mode of the DK8KW-DF6NM experiment is permitted to us in the USA.  If you see things differently on this topic, do e-mail and tell us why. Regarding station identification, the FCC rule at §97.119 “Station Identification” spells that out.
