More One Way


Sunday, August 2, 2020

One way today

Around 15:30z today I was able to get some "flags" in Europe on 6m.  After trying off/on all morning.  I would guess that these flags are probably Meteor Scatter assisted, folks in EU said they were single decode events...at least some of them.

Still it's worth noting that they occurred since it's August now.  Likely nearing the end of 2020 Es season (hard to believe how fast it went this year).

"Boing"

If you are using "VAC" by the same name found here: https://vac.muzychenko.net/en/download.htm
Please READ what it says on that page about the Trial version YOU are using (well if this pertains to you).

If you are using VOX to key your radio (or using Remote Ham Radio [in this specific case]) and you happen to notice your are Transmitting every 5-6 seconds - STOP!

If you are using the "VAC" noted above, after 30 seconds it will begin to emit in a female voice the word "Boing".  If you are using FT8 it will do this while you are sending FT8 *AND* while you are in the Receive sequence at least 2 times "Boing" <5 sec> "Boing".

Most folks this happens to didn't read the warning on the download page, and or are not even aware that they're using the "Trial" version.  They are normally shocked that this is Them, and tend NOT to believe it.  LOL what can I say....humans...go figure.

Anyway...the way to STOP this is to PAY for your version (see the URL above!) OR use a truly free version made by someone else.  There are several free virtual audio cable software.

In this case I bring it up because several of us in the Maine and Nova Scotia have spotted this occurring from the FN65, or FN64 area and very strong.  It also coincided with the time that WA9PIE showed up on Remote Ham Radio this morning.  It stopped around 12:42 UTC.

Here's video of how this looks on the Receiving side here.



A follow up to this Mike emailed me back and kindly thanked me for letting him know about this.  It's nice when we hams are able to communicate effectively, and cooperatively to resolve a mutual problem.  So Thank you Mike for that!

W4HLR/b

Please notice the beacon I'm pointing to first in this video, this is what a 'typical' CW beacon looks like regarding signal quality and bandwidth required.

Then notice W4HLR/b using about 1968 Hz :(

2x "WOS" LFA Stack Update

About a week or so after I put up the two "WOS" LFA's I decided to add 'switching' so that I could have "TOP ONLY" antenna, "BOTH IN PHASE" and "BOTH OUT OF PHASE".  I also moved the "delay line" (1/2 wave length of coax) from the Bottom antenna to the top for the "BOP" (both of of phase).  

SWR for TOP only remains 1.00:1 (I'm still shocked by that)
SWR for BOTH through the power divider I built is 1.2:1 "BIP"
SWR for BOTH in "BOP" is about 1.15:1

SWR does not change when I turn the top antenna and the bottom remains fixed.  

The "BIP" mode (both antennas in phase) works excellent thus far.  There haven't been enough openings to EU to really fully test any of them yet.  

I have noticed in "BIP" the noise drops enough to notice.  1 to 2.5 dB
In "BOP" noise seems to remain about the same as "TOP" only...when the band isn't open.  Just using Baby Monitors to test with.  Not really a good test since I think "BOP" ("UpTilt") really likely only shows a major improvement when the band is open, and signals are coming from High Angles.  But I don't have enough experience with it yet to know.

Last night when I had OH, SM, LA and TF in here "BIP" made the difference.  Without it things pretty much dropped out.  This seems to matter most when in my testing so far when signals are quiet weak.  making the difference between decoding and or hearing the DX vs. NOT.  

I'll need more time with this setup but so far results are really encouraging.
