Reverse Beacon Network surprises

 Last weekend I took part in the WAE DX CW contest and most of the time when I calling "CQ contest" on my second monitor I have the RBN or reverse beacon network up and running. The main reason for doing this to see where my signal is reaching and if it is targeting in the case of the WAE contest Europe. Now and then I see my signal has been spotted in both interesting places and far away places. This contest was no different, on Sunday morning I was spotted in New Zealand by ZL3X multiple times from 4dB to 11dB, VY0ERC in Eureka in Nunavut at 7dB and finally 5W1SA in Samoa at 8dB. Nice to know my 100 watts are getting out there!

Magic Band Summer Season



This summer’s Sporadic-E season has pretty much wound-down once again. As E seasons go, this one ranked right up there with the worst of them but this comes with some provisos.

Over the past several years, my only interest has focused on Europe and Asia, looking for any DXCC entities that I have not yet worked and I tend to ignore most domestic openings unless the MUF appears to be climbing into the range of 2m.

There were several openings from here in British Columbia to most regions of the US and Canada, so many would likely disagree that it was a poorer season than normal!
 

Unlike last year when we had several good days to Europe over a two-week period, this year’s fireworks were pretty much confined to June 12, when the somewhat unstable polar-path to Europe jumped from country to country for several hours. In spite of making 62 contacts to Europe, only one new country was worked when 9H1TX in Malta replied to one of my CQs! Other than him, there were no other signals being heard at the time but after our QSO, his fellow countryman, 9H1TX, also appeared ... so it was exciting to find two rare 9H1s in the 6m log! For about 4 minutes, the only two signals in my FT8 waterfall were both CQers from Malta! Note the power and antenna being used by 9H1LO ... it doesn't take much when the magic appears, albeit momentarily.
 


 
Last summer’s E season was not as heavily influenced by the active Sun, unlike this summer’s constant stream of solar flares keeping the polar regions anything but calm and quiet … a seeming requirement for good transpolar Es on 50MHz from the west coast.
 
Last year produced 8 new DXCC entities and in most cases, like this year, signals were strong enough for CW but almost all DX prefers the few db advantage offered by the FT8 mode. Exchanges can be made MUCH more quickly on CW than the snail-pace of FT8. The addition of 9H1 brings my 6m DXCC confirmed total to 109.
 












If Cycle 25 continues to grow as it has been (in small spurts), it’s difficult to predict if there will be any long haul F2 propagation in the late fall or not. In previous cycles we’ve needed to see some steady flux values in the 200 or higher range for several days in a row … at least for us here in VE7 land.
 
If the F2 MUF does indeed manage to manifest itself, we should expect to see early morning openings to the New England / NY regions with blowtorch signal levels before seeing the path crawl down the eastern seaboard then possibly into the Caribbean and South America. Later in the afternoon, expect signals from Japan and the far East for several hours up until sunset, once again at bone-crushing signal levels. There are few things in ham radio more exciting than experiencing 6m F2 and hearing the level of signal strengths that can be reached when operating near the edge of the MUF.
 
If not this fall then hopefully in 2024 for sure … but as of now, it’s anyone’s guess as to if or when the rare winter magic will appear once again!

Question for those who use Blogger.


 

Good afternoon fellow Bloggers, I have been having an issue for some time now and have just ignored it. The time has come to see if something is up at my end or if others using Blogger have this same issue. I have searched the internet and the Blogger site regarding the issue. There has been advice but nothing has worked.


The issue is I want to add a blog to my blog list and I attempt this as follows:
1. I visit the home page of the blog I want to follow and copy the URL. 


2. In my blog I go to (Blogger blog) and click on Layout. 


3. In the layout I have a gadget called "Blogs I follow" and I click on edit. 


4. This shows me all the blogs I follow and when I scroll to the end of the list I am given an option to "add a new item" 


5. I click on "add new item" paste the blog URL on the line called "blog URL" and click continue. 


In the past when I did this the name of the blog I want to follow would populate in the line above the blog URL and then ask me again if I wanted to save it. I clicked yes and it was done. For some time now I add the URL of the blog I want to follow and click save and the message I get is "Could not detect a feed" I do have the option to click ok but I am informed that I can still click "ok" but if I do the time and date will not be shown....whatever that is. So I click anyway the complete URL is shown but now the only option I have is to cancel it and I am not given the option to save it. Not sure why this is happening.

What is unique about THIS particular QSO party?

Olivia is the digital (HF) protocol developed at the end of 2003 by Pawel Jalocha. This is the 20th Year Anniversary QSO party by the Olivia Digital DXers Club (we’re on Clublog).

ABOUT OLIVIA DIGITAL MODE ON HF

Below are suggested frequencies on which can be found Olivia signals (note: Olivia is a weak-signal mode, NOT a low-power mode). While it is easy to spot a STRONG Olivia signal anywhere on the waterfall, by using these suggested calling frequencies at least once and a while, you will enable us to find your signal when the signal is too weak to hear and too faint to see on the waterfall.

Olivia can do well with weak signals. Yes, our suggested 8 tone with 250 Hz bandwidth results in slow transmissions. But it is one of the better settings when attempting to decode very weak signals. Once you make contact, you can move up or down a bit, away from the calling frequency, and then change to 16/500 to make the conversation go faster. But, on a calling frequency, it is advisable to configure operations in such a way as to increase the likelihood that you will find and decode that weak signal.

In the following list, CENTER is where you place the center of the software’s cursor, and click to select that center frequency on the waterfall. If you use the DIAL frequency from this list, then click 1500 Hz offset up the waterfall (1500 Hz to the RIGHT of the LEFT side of the waterfall, if your waterfall is oriented horizontally with the lowest frequency on the left). This results in the software and transceiver being correctly tuned for the CENTER frequency.

The listing shows CENTER, then DIAL, then the number of tones and the bandwidth.

 CENTER        DIAL         Tones/Bandwidth (Notes)

1.8390 MHz    1.8375 MHz   8/250 (ITU Region 1, etc.; Primary International)
1.8270 MHz    1.8255 MHz   8/250 (ITU Region 2; Secondary)
3.5830 MHz    3.5815 MHz   8/250
7.0400 MHz    7.0385 MHz   8/250 (ITU Region 2, etc., Primary International)
7.0730 MHz    7.0715 MHz   8/250 (Secondary)
10.1430 MHz   10.1415 MHz   8/250
10.1440 MHz   10.1425 MHz  16/1000 (Potential - be mindful of other stations)
14.0730 MHz   14.0715 MHz   8/250
14.1075 MHz   14.1060 MHz  32/1000
18.0990 MHz   18.0975 MHz   8/250
21.0730 MHz   21.0715 MHz   8/250
24.9230 MHz   24.9215 MHz   8/250
28.1230 MHz   28.1215 MHz   8/250

REMEMBER THAT IF YOU USE THE DIAL FREQUENCY (THE SECOND FREQUENCY PER ROW), SET YOUR WATERFALL CENTER AT 1500 Hz)

ALSO: If your software is able to decode/encode the Reed-Solomon Identification signals (RSID), please turn on both received and transmit RSID. An example is shown in the following video, which demonstrates enabling RSID in a popular software suite: https://www.youtube.com/watch?v=lBIacwD9nNM

Please share this everywhere possible, as part of our effort to rekindle the love for our conversational mode, Olivia.
