RX:Grundig Yacht Boy 80

Long wire end feed antenna (75ft L 33ft H..75sqmm Cu wire multistranded) RG6 cable ..with a splitter box circuit with T50-6 toroid at RX end 

Monitored Mode:J3E Class of emission(Amateur Stations)

All time mentioned  in Indian Standard Time(ist) and where possible in Coordinated Universal Time(utc) also.

Band Noise:There was heavy noise on the band from the morning,though I was copying VU2DBM comfortably on 7070kHz lsb also VU3INI with difficulty  prior to 0838ist(0308utc),from 0838ist, the noise went suddenly and after that excellent copy all around.

7070kHz lsb

Noise gone around 0838ist 

(0308utc)from 40mb.

From 0839ist onwards on 7070kHz lsb..

VU2DBM 59 with QSB sometime..VU3INI 54..VU3WTS 59...(went  on QRX )

VU2DBM VU3INI both from Guwahati,VU3WTS from Titabar

Joining 0855ist onwards VU3ZHD 54..

VU3HZD joining from Dumka ,Jharkhand

Also joined 0859ist(0329utc) ..VU3HZW 56 with QSB 

VU3HZW also from Guwahati

Also broke around 0846ist .. VU3HZT 55,from Naharlagun,Arunachal Pradesh but perhaps not copied by others.

0903ist..onwards VU3HZW..58.QSB ..VU3INI...56..with slight 

0907ist VU3ZHD 54..VU2DBM still 59 

QSO going on..

To quick review..

VU2DBM 59 VU3WTS 59 VU3INI 54 VU3ZHD 54 VU3HZW 58 56..

VU2DBM VU3INI VU3HZW on air on 7070kHz lsb @0918ist ..(0348utc)

VU2DBM was on air with his 30 year old Yaesu FT747 GX but today there was no sharp tone in his signal and with excellent audio quality and I thought he was using  his Icom IC 7300 with different settings but later he declared on air he was indeed using his FT747 GX.

Here is the audio link recorded around 0839ist :

Another audio link recorded around 0905ist:

https://app.box.com/s/7tvlrp22yfs8osv0ytnxaujliq7gehlq

The audio recording quality may be so good due to my not so good quality recording device.

More reports,observations etc soon.

Monitor's Note On Morning 40mb Noise QRN or QRM?

From time to time on 40mb band in the morning , I hear heavy noise and it is sometime difficult to copy any stations.Take the case of March 16th.

40mb and was noisy here right from the morning on nothing audible as such due to heavy noise..and there was no electric  energy Mains  supply from the APDCL..Electric Energy Provider ..from early  morning due to breaking of electric post.....but still noise washeavy..that means it was band noise not electric...noise..QRM and it was QRN .I  also disconnected our inverter  and ...total electric silence..still..the band was noisy on 40mb.I was finding it difficult to copy on 7070kHz lsb VU3HZW from Guwahati and VU3HZT from Naharlagun, Arunachal Pradesh earlier in the morning.But on 10MHz  14MHz ..& 15MHz bands...little noise ..and on broadcasting bands even medium wave bands, I was copying broadcasting stations comfortably.

One thing also came to my notice in the evening,sometime  even inverters , lights etc on I can copy 40mb amateur stations comfortably.

So, it is now clear to me beyond doubt the noise now on 40mb in the morning is band noise ..atmospheric ..

For new comers to this hobby , QRN means a short term to describe natural noise like band noise atmospheric noise like lightning ,solar stroms etc  and QRM means man made noise radio frequency interference  ..(noise) generated consumer electronics goods ,powerlines etc.

Special Log on 20mb which I like to share ..
