Monitor's First Note

On Band Condition:

Slightly noisy and later noise from 0649ist(0119utc onwards)..the rainfall noise with burning effect slightly higher level on 40mb..but later in the morning from 0856ist(0326utc) onwards,the noise mentioned gone all of a sudden..later monitored with little noise.I am not sure  and also slightly confused whether it was band noise or noise due to powerline of our Mains AC  Power supply Company or else.But I am sure its source is  not in our house or in our campus.

7050kHz lsb
0649ist(0119utc onwards) 

VU2RZA relatively  weak signal than other mornings with noise, heard a few breaker calls..could not copy..

0656ist onwards signal strength of VU2RZA improved vastly..59..but weakening of signal later..as QSO in progress  ..no copy of VU2JF VU2OOO  53 43 with QSB YL Rani from Guna.. XYL of  OM VU2OO

Monitor's Second Note:

Earlier before 0856ist, I heard VU3XBP& VU2YPB's signal strength(QSA) was strong I could copy with noise,even VU3HZT was copied but not as strong ..I copied VU3ZRI & & VU3HZW  with difficulty,VU3OKB with noise somehow. But from 0856ist the noise vanished and....I could listen with little noise..( as I read in my school days..little a little the little...in English Grammer..Hi Hi)

0856 to 0918ist (0326 to 0348utc)

VU3HZT 59 from Naharlagun ..VU3XBP VU2YPB both 59 VU3INI 58 VU3ZRI 56 VU3HZW 58 .

Here is the audio clip recorded at around 0917ist(0347utc) on 7070kHz lsb :

Monitor's Third  Note:

Earlier VU3HZW heard  with very sharp tone ..difficult to copy..later improved tone...with slight distortion..but no problem in  copying..Except VU3HZT all stations were from Guwahati Assam...India..My place ,Abhayapuri(NL56hi)...107km approx. Aerial distance....from Guwahati...and Naharlagun is approximately 313.1km approx. away aerially from my place 

VU3HZT OM Vijay Sonam from Naharlagun is the only active amateur station(on HF) now in ,Arunachal Pradesh.

More reports,observations etc soon.
