9N7AA Nepal News 7 December 2023

Just back from a resort at the edge of Kathmandu valley but much higher, with a clear shot from 270-90 degrees, and far enough not to suffer from the crazy man made noise I have in KTM - keep the fingers crossed. I am renting a bungalow over the winter period and the German owner kindly allowed me to install antennas for the season. The place is not that far from my home, but it takes 2-3 hours to get there due to traffic and road condition up in the hills.

Spent the whole day today building verticals of different shapes and all seem good, but was not able to test the noise/QRM as the guesthouse was still fully occupied this weekend. Will be back next week on Friday for two nights and then selected weekends until end of February, if no surprise with the local QRM.

160 & 80m wire vertical & inv L are installed on an 18m SpiderBeam pole and tuned fine, while the 40m wire, also attached to the same pole, just doesn't load properly. Will build a separate fiberglass pole supported wire vertical next week instead.

Hope all the stars align and finally allow for some decent low band runs!

9N7AA Nepal News 25 November 2022

Last week I finally installed an 80/160 quarter-wave sloper, stretching over two adjacent land plots and a bundle of power and optical cables. I have the neighbours’ permission to keep the antenna up till end of March. Both bands tuned very well, but there is a lot of RF in the shack and my ears must be lighting up during the TX. The initial operating results are very discouraging, though. Not only is the RX a problem, which I have expected, it seems that I don’t reach out either and the FT8 reports from nearby Asian stations are in the range of -15 to -20.

I was monitoring my transmissions remotely at home/S53R and on 80m I was barely decodable on a phased verticals array on a hilltop location, while not a beep was heard, or even a trace seen on 160m FT8 just before the 9N sunrise. QRM is plain and simple – out of this world! Nothing new and very little I can do about it. Only with the use of DXE NCC-2 I managed to “extract” a couple of stations on 80m. They were mostly from Asia with just two from EU, bordering Asia as a matter of fact. More tests are needed and the upcoming CQWW CW will be a good reference. Stay tuned.

On the other hand, higher bands (17-6m) are surprisingly good with substantially less QRM. Please note that 60m is not permitted in Nepal.

9N7AA News For the 2nd time, an attempt at activating 80/160m outside of Kathmandu didn’t really work. Got to the Turtle Hill (1,810m asl) early on Friday and with the help of Nabin, 9N2NK, the 40-30 antenna was up and tuned about half an hour before the sunset. 80 and 160 was to follow Saturday morning, depending on the noise. Initial check, still during the daylight, had shown the noise on 60/40/30 was surprisingly low, around S2-3 without attenuator engaged on the radio. But the moment sun went behind the ridge, noise started to raise sharply. At that point I blamed the large flood lights at the resort which were all switched ON for a bachelor’s party. I run some CW on 30 and 40m with mixed results, slightly better compared to my QTH in Kathmandu, but still a struggle with most of the signals buried deep in the hhhhrrrrrrrssssshhhhh. Very familiar sound - feels like pulling a coffee grinder over my ears. Something I’m very much used to from operating my station at home in the city. The party ended around 1 AM and I went to switch off all LED lights in the compound. To my big surprise, there was absolutely no improvement! I stayed on 40 and 30 for most of the night, freezing my rear end off without electrical heating if I wanted running the amp. The resort only has two shabby 15A power lines. The village on Turtle Hill is very small, with only 5-6 houses along with the resort, hence I don’t believe the noise is generated locally. This made me think of a different noise source – Kathmandu! It starts just a kilometer away as the crow flies, although it sits at a 500m lower altitude. From the hilltop all one can see is a huge sea of lights and a deep hum from the big city. After two nearly equal experiences I am now convinced, this is the case. Looking at the noise levels on 160-30m, best on 30m at S8-9 and progressively worse on lower bands, this makes any location on the Kathmandu Valley Ring pretty much hopeless for serious DX-ing and contesting. I faced exactly the same situation last year a bit further to the East, beefed up with a nearby HV X-former sparking. Something any future DX-pedition to Nepal should consider very seriously. If the low bands and night operation are the target, then Kathmandu Valley is just NOT an option. There is also no space for any beverages due to very steep and complex terrain. Low lands in the Terai region would be better, but it is heavily populated. Last but not least, it’s the man-made interference that threatens our hobby today more than anything else!
