WX:Clear Sky,good morning sunshine,cool

General Observation on Noise etc On The Band:
No motor boat type etc noise observed today morning as such,not a signal station heard upto 0722 Hr IST,not much activity.

7050kHz lsb The Hembel Belgaum Net  0722-0740 Hr:
It was from 0722 Hr IST onwards very weak signals of amateurs checking calls could be heard but rather very weak to copy here.Around 0724 Hr IST onwards heard breaking call of VU2RZA strong signal,VU3FTP, and around 0727 Hr IST call of VU2JGI
0729Hr VU2RZA 59 VU2PMY very weak to copy etc
0731Hr VU2KOC back as net controller weak signal, several breaking calls made including VU2JGI 58
0732Hr VU2RZA 59 again as usual the case here 
0735Hr VU2JF 59 VU2KOC fair signal 54,VU2RRX weak
0736Hr VU2JGI 56 VU2KOC 54 53 signal going down further

7130kHz lsb Rajkot Net  0742-0753Hr:
Heard CQ of VU2SMN with fair to weak signal,QRM from non-ham stations(?) were there in unknown language heard  with weak to fair strength on the frequency,
0746Hr VU2OO breaking,VU2JF 59,perhaps VU2OO OM Guptaji from Gune could not copy VU2JF from Rajkot,A41LD no copy 
0751 Hr Heard VU2JF 59 this time copied A41LD weak for briefly signal going up & down

7065kHz lsb Delhi Net 0810-0813Hr
0811Hr 9N1CA 59 VU2DED moderately strong perfect copy i.e. 55 VU2OO weak 
VU2PZA no copy VU2YK no copy  

7145kHz lsb Eastern India Net(?):0814-0846Hr:
9N1CA Om Arun Singh from Near Pokhra Nepal gave Calls on the frequency
0825Hr onwards:
VU3OKT ,OM Dipak Chakraborty from Kolkata,weak (53),9N1CA 59 on average sometimes with QSB sometimes,VU3BTP 59 ,Handle Harsha from Bokaro Steel City on average,later VU2OWB,Handle Avijit from Khaspur West Bengal  joined ..59 signal strength
0835Hr for two minutes or so on 7145kHz on AM Mode
 i.e. A3E class of emission:
9N1CA  & VU2OWB went to AM mode to check reception quality on their respective location.I could copy both the station.9N1CA  copied perfectly but VU2OWB with slight break in transmission..audio clipping type( might be due to PTT problem)-might slight distortion might be there as pointed out by 9N1CA.VU3OKT also  joined on AM mode as breaker you could say I only heard once giving his report to VU2OWB.
It was a good experiment to check reception quality in AM Mode also from time to time.
Later they returned to J3E mode of transmission.
Later,VU3WTS,OB Bimalendu Chutia from Titabar,Assam a friend of mine  gave  call on that frequency but there was  no response.
Monitor's Note:
Its my pleasure to share my experience of listening to A3E mode of transmission of amateurs.
First time I heard amateurs operating on A3E class of emission i.e. AM mode between Late VU2RCH from Nagaon(Assam) & VU3YPB OM Paresh Brahma from Guwahati on 7070kHz .The reception was noisy weak copy of VU2RCH as far as I could remember.One and half years back VU3TQF,OB Ravi Boro from Guwahati gave transmission on AM mode on 40mb to check his home built transreceiver.After that VU3OIP ,Sultan Saleh Ahmed from Barpeta Town,so far my nearest active station also tested reception on AM mode from his newly bought Yaesu FT450D with me.Also a few years back two senior amateurs of India  also tested reception with each other on 40mb in the morning on AM mode.I heard their QSO.And today morning ... another occasion to tune into AM transmission by amateurs on 40mb!!

I am still in monitoring / listening mode because I transceiver is not yet ready.I may be on air within this year or so.

More such reports/observations etc soon.
