Antennas / Re: Linked Dipole
« Last post by CPR on June 25, 2018, 08:33:45 AM »
I was out in the field this weekend. Setting up the linked dipole I realized it picks up much more noise than my endfed random wire. The wire is at S1 max, the dipole at S4 sometimes 5. A lot of QRM. I tried to make a contact but there was this damn contest on all bands, no one responded as everyone were cq contest. Very disappointing.
Although I somehow prefer the linked dipole because its resonant without a tuner, I am quite sad because of the QRM.

You f--ker, LOL! Well done.

Maybe I should get a similar case for my BitX40 still in its plastic box and not spend $100, but if I get some extra $ why not...

Since then I have installed the USB cable between the Arduino Nano and the rear IO board, and also fitted the S-Meter sensor, and enabled it in the (KD8CEC 1.08) firmware, although it seems like it's going to take a bit of tweaking to get the bar graph levels 'right'.

You just might make me spend my money Andy, tempting...

It's Alive!!!

Check out the FB album and keep an eye on my YT channel. The video compilation is being rendered as I type. Can't TX yet until after next week (hopefully when I pass my intermediate exam) as I've modified the basic kit somewhat.

Really pleased with it so far.

Well I saw the video.. It looks like a toaster or oldschool radio. If you got that used I should get some radioactive testing probes to check the geigermuller tube if its still working.
You can try to convert röntgen to sieverts using this: https://www.unitjuggler.com/equivalentdose-umwandeln-von-rem-nach-Sv.html
0.5 Röntgen is 5 mili Sieverts. Thats pretty high. I am not sure if the unit you have shows those readings in unit per hour or what?

Reviving an old topic...
I got myself a TerraP+ geiger counter. They seem to be pretty good, in Ukraine and Japan they are beeing used a lot. I live near a nuclear power plant (30km), so that's a wise investment IMO. Once or twice a week I measure the gamma dose. Actually I made a video once about radiation 101, trying to solve some mysteries about it:

Anyway, I dont think TEOTWAWKI will ever happen. The government will establish law sooner or later. IMO prepping is just about to fill the time gap of lawlessness until it is functioning again.

You defiantly will not regret learning morse code. It’s not like buying a computer interface to run FT8 and after a few contacts getting bored of it and regretting the purchase. Learning morse code is a lot more rewarding and even if you eventually bore of it, it will always be useful. It’s not a product, it’s a skill.

I agree that digital modes like FT8 have limited usefulness to the preppers but that’s not their target users. On the other hand, FSQ was designed specifically for emergency comms. Modes like FSQ and Olivia are very handy to the emergency communicator. FSQ can even send messages while the receiving station doesn’t have an operator present at the radio.  They perform better than CW. They can send faster and in worse conditions. Their only downside is that they require a computer. This adds weight, complexity, points of failure, and power requirements. If you can afford the additional weight and power requirements they are a good way to go.

I have an IC-706 in my suburban and am setting up a mobile station that can run digital on all HF bands. This mobile station will be able to run digital modes for extended periods of time until I run out of gas. Then the foldable 22 watt panel will allow me to run the station for short intervals.

Code: [Select]
This thread got me thinking though, when was the last time I even heard a QRP station?
Do you do much CW? I’m in the El Paso area and I have regular QSOs with QRPers on CW. I’d estimate that ¼ - ⅓ of my CW QSOs are with someone running QRP.

I was referring to QRP on SSB, I don't do any CW yet but it is on my serious to do list this coming off season (HVAC Contractor).  I will probably go ahead and get MRP40 just to play around until I can become proficient with CW.  The digital modes such as FT-8 are neat for testing antennas but I really don't see them being useful as much as CW in SHTF.
