Remote your shack, how do you do it? |

Hi
as a keen VHF operator, I am often frustrated by the good openings happening while I am at work. . . maybe you have had similar frustrations, maybe you could add your input to this thread.
What really sparked this up to 'frenzy' level was the opening on 50 MHz across the south pole last December, I would have to come to work knowing that some time mid morning there would be most probably be an opening and I would be at work. Arrrgh
Okay, so my work involves me spending a lot of time in front of a PC, with the occasional slow time where I have to wait for other processes to finish, step one how do I get to connect to my Shack PC from work? For me this step involved creating a free account with TeamViewer which allows me to install their software on the work PC and the home PC. I can then as needed connect to the home PC.
To control the rig, it is connected to the Shack PC via either a mix of USB and serial data, so the WSJT-X and FLdigi software has control over the rig. So now I can at least run JT65, WSPR or FT8 from remote (even from the teamviewer app on my phone).
Next step, how do I control the rotator, hmmm this step has caused me a lot of headaches as to what to use, I eventually settled on an EA4TX rotator controller that plugs up to a USB port on the PC and can be controled a number of different ways.
Okay, I can QSY, change modes, turn the antennas but how do I turn on the 50MHz amp? enter a little box called a RLY-8 purchased from an ebay seller (seller Id is: IOT-HUB) here in Australia just recently for $110. It has an ethernet port and a USB port and can control 8 different devices via its isolated relays. I have not connected this to my system as yet as I am working on the best way to switch the 50MHz amp, 144 MHz amp and a few other accessories in the shack but my initial testing looks good (no birdies found on the bands from this box).

9:1 OR 4:1 ?? |

I am about to put up a Dipole antenna but unsure what Balun would best suit.
I can only place a wire up that is 88' in length.
At the centre it will be 33' and the ends drop down to 20'.
The Antenna will be fed with 450 Open Wire which will be 33' to the ground where the Balun will sit.
The run back to the shack will be around 40' where I will use LMR195 to the Tuner.
I have purchased a 9:1 but now wondering wether it should have been a 4:1 ??

Got an email today that says it came from my email account but originates from 90.165.54.92 with subject "XXXXXX@XXXXX.XXX is hacked". I am aware of others who have received the same email over the last month or so, maybe from a different IP, but I didn't personally see those messages. Funnily enough, no trace of it exists in my Sent items - simply because the email address was spoofed for the purpose of this email....

Hello!
My nickname in darknet is delainey77.
I hacked this mailbox more than six months ago, through it I infected your operating system with a virus (trojan) created by me and have been monitoring you for a long time.
If you don't belive me please check 'from address' in your header, you will see that I sent you an email from your mailbox.
Even if you changed the password after that - it does not matter, my virus intercepted all the caching data on your computer
and automatically saved access for me.
I have access to all your accounts, social networks, email, browsing history.
Accordingly, I have the data of all your contacts, files from your computer, photos and videos.
I was most struck by the intimate content sites that you occasionally visit.
You have a very wild imagination, I tell you!
During your pastime and entertainment there, I took screenshot through the camera of your device, synchronizing with what you are watching.
Oh my god! You are so funny and excited!
I think that you do not want all your contacts to get these files, right?
If you are of the same opinion, then I think that $543 is quite a fair price to destroy the dirt I created.
Send the above amount on my BTC wallet (bitcoin): 19D67Tgb3neJiTHd8pZDEBYmUn2qSjxEeB
As soon as the above amount is received, I guarantee that the data will be deleted, I do not need it.
Otherwise, these files and history of visiting sites will get all your contacts from your device.
Also, I'll send to everyone your contact access to your email and access logs, I have carefully saved it!
Since reading this letter you have 50 hours!
After your reading this message, I'll receive an automatic notification that you have seen the letter.
I hope I taught you a good lesson.
Do not be so nonchalant, please visit only to proven resources, and don't enter your passwords anywhere!
Good luck!
"
To the would-be scammer : sorry, it isn't going to work !!!
To others : ignore and delete !!!

G'Day To All,
My scenario is as follows:
The back yard only allows me to string out a 88' Dipole.
The dipole centre is 33' while the ends come down to 20'.
From the feed-point is a 33' length of 450 Twin Lead to ground level where it enters a 9:1 Balun, then 40' of 50 ohm low loss back to a tuner.
I particularly like operating on 160 & 80.
At 160, the Impedance at the balun will be 270 ohms, not a big drama, but on 80 the impedance falls to 50 ohms.
Will the signal on 80 be greatly affected do you believe?

Peggy Sue Gerron, ex-K5PSG, SK
ARRL reports Peggy Sue Gerron, ex-K5PSG, of Lubbock, Texas, who inspired singer Buddy Hollys 1957 rockabilly hit Peggy Sue, died on October 1. She was 78
First licensed in 2004 as KE 5 AKW, she later obtained the vanity call K 5 PSG. Her license expired in 2014, and K5PSG has since been reissued.
Peggy Sue went to high school with Buddy Holly and later married The Crickets drummer, Jerry Allison. As rock n roll history has it, Holly originally titled the song Cindy Lou, but Allison convinced the singer to change the tunes name to Peggy Sue.
After Hollys death in 1959, Peggy Sue toured with The Crickets after the band got back together. Over the years, she made public and media appearances all over the country.
She said her participation in the 2004 W 5 B special event in Lubbock commemorating Holly, helped inspire her Amateur Radio aspirations.
You can do TV specials, and you can be interviewed by the very best DJs, she said, but there is nothing like the feeling of putting your finger down, and transmitting your call sign, and having somebody answer back.
