From Monitor's Desk Special Monitoring Observation On 20mb

 My Listening/Monitoring  Pleasure  But Others................
A few recent  Observations on 20mb reception here at my place, Abhayapuri(Assam)(India) via both long wire end fed & later with dual bander 40mb/20mb  Inverted V with one:one balun at the centre feed with RG58 co-axial cable approx 33ft ht..North South  40mb East West 20mb..RIG used Yaseu FT 891




40/20 MB Dual Bander Centre Feed Inverted V Dipole Antenna  With A Pulley Support

From.September ,2024 onwards ...Short distance reception has been unprecedented improvement  on 20mb ..I can copy VU3OIP from Barpeta..with  HIS cobweb ...etc  just around 33km approx..aerially . from Guwahati 107-109km aerially ..even VU2DBM WITH YAGI ..& VU3HZW ...with homebrewed Inverted, OM  VU3DUK  with his Diamond WD330s..perhaps.Believe it or not during morning period, during this autumn-winter, I heard VU2DBM in the morning loud and clear on 20mb in the morning during 0800-1000ist approx.He was in QSO with 9N1CA from Nepal  several days as far as I could recall on 14200/14195kHz usb.And even S21 stations on 20mb loud and clear.Many QSOs in the morning were heard on 20mb amongst West Bengal based amateur stations on 20mb too.Sometimes S21 station joined them specially S21RW from Khulna.I heard him loud and clear on 20mb.

Earlier only SK VU2RCH from Nagaon ...aerially perhaps 139,km approx ± a few kms away from my place,and with his horizontal dipole  WAS the station I heard on 20mb from Assam with satisfactory signal .twice only perhaps during 2017..no Guwahati based heard.on 20mb. And in fact later when VU2DBM Installed his multiband yagi (20mb 15mb etc )...then I could hear sometimes his signal with very very weak signal strength here at my location on 20mb specially in the evening.Later when VU3INI became active  on 20mb perhaps in 2022-23 I heard VU3INI on 20mb with his EFHW antenna twice with good strong reception on 20mb.I heard several rounds of QSO between 9N1CA & S21RW too in the morning on 20mb.Both of them heard loud and clear here.I am sorry I misplaced my monitoring log details notes in loose sheets somewhere and my laziness also to blame for such delay in sharing such interesting observations on the 20mb band.As per my general views plus my long time observations plus monitoring observations, 20mb is long distance communication band and also the best time of operation in our area is the afternoon to evening.But this winter season, it is an exception.Let us observe the behaviour of 20mb  in coming autumn-winter and also in the spring-summer seasons.

More observations/radio news/monitoring reports etc from time to time.
