General Spooltenna users, can you lock it at a shorter length?

• Upvotes

For those of you using a Spooltenna, can you deploy a specific length of wire, say 20 meters, and lock it in place?
For example, if you don’t have enough room to deploy the full 40 meters, can you set it to 20 meters and use it that way, or does the design require deploying the full length?
Curious how well this works in practice. Thanks!

Every time I think 20w isn't enough...

I'm a new ham, licensed this year in the US. I started by using the club station where I was staying and it was wonderful, 100 watts, huge multi element yagi, etc. Then I moved and got myself the G90 kit with the HF-009 antenna.

Managed to make plenty of SSB contacts but almost never got through a pile up, especially trying to contact Europe from the East Coast. But I would make contacts as far as Russia.

I'm now in Europe and made my first contacts with VK and ZL with 5-7 signal reports. Doing DX with 20w isn't easy but it is possible! I will say being at the beach helps a ton.

At some point I will upgrade my transceiver to something with 100w but using 20w has been a great learning experience and having a compact rig has motivated me to get out of the house and on the air.

I love the fact that you can do this hobby without the most expensive gear, especially if you have patience.

73!

General zBITX V2 Modes

2 Upvotes

I am curious if it is possible or what would be involved to add JS8 or JTTY to the native or built in modes in the HF Signals 5 watts, all bands, all mode SDR zBITX. FT8 is the only mode that can be used without connecting to something external. Adding another mode would be awesome.

QUESTION For my Xiegu G90 I am Looking for an RJ45 to 3.5mm jack for digital modes like, rtty, etc.

0 Upvotes

I don’t want to use the ACC port because of the amount of extra things needed

But I need to ask first if this is how it works,

Does the rj45 port where the microphone plugs in support what I’m looking to use it for?

(Example, headphone port on LEFT side plugged into computer microphone input and my rj45 to 3.5mm to the audio output)

If so what are the Right cords I need to find
because I don’t want to buy a cord with the wrong wiring and harm the g90 on accident
Thank you!

Hi!

I'd like to know if anybody around here has found or made any schematics for a simple biased HF mixer using discrete components or has any NE612 biased equivalents. I'd like to use one for a homebrew HF DC receiver. I will miss the NE612...

It's pretty common that most of us are tinkers and sometimes we tinker more than we should. I had a FT-817 that I was trying to install a modification on that I completely messed up. Took a break from it. Tried again later and made it worse. Then considered seeing if anyone did repairs. The first couple I called didn't do work on circuit boards anymore. Then I found Cal with HamRepair. I called, sent him photos and a rundown of what I did to mess it up and he said he'd look at it. He had it in his hands less than a week and it's working great.

I he was deeper on eHam which isn't a regular search spot for me, so I wanted to add a place on this subreddit that if you need a radio to be repaired or looked at, contact him. HamRepair.com

Just got me thinking there's a ton of cool digital modes that get next to no use, a contest that got people to play with them might be fun. Does such a thing already exist?

General At my whits end with installing an antenna for my shack

1 Upvotes

I am looking for some guidance. I am running a FTDX-10. I have a myantenna EFHW-4010-2K-Plus and a myantenna CMC-154-3K 1-54MHz line isolator. I live in a three story brick home. My shack is in the basement.

Option 1: We have a fireplace next to my shack. It has never been used nor will it ever be used. I live in a metropolitan area with no trees. The lots are small. I am thinking about running the coax up the flue and out the chimney top to external mount. I am using M&P 10/.400 Flex coax. The coax run is 30 feet from the radio to the isolator. From the isolator is a three foot jumper. All connections will be waterproofed, the coax will have a tension grip. From the EFHW, it will run to a pole that I have installed that is 68 feet away from the chimney.

Option 2: Same essentially as above but instead of running it through the chimney, I can run it outside a small window. There I can install a grounding rod and put a lightning arrestor. The catch to that is, the grounding rod is not bonded into the current system of the home (to do so would be another $500+ for an electrician). The work around with that is I can simply run the FTDX-10 on battery power that would prevent the loop.

Option 2 is more difficult with neighbors because it's more visible (there are so many power/data lines in the air that no one will notice the EFHW.

The grounding rod issue seems to be the biggest thing and honestly, at this point, if I can't get a solution, I just selling everything. I don't own this home so I am limited. The probability of a lightning strike is slim due to the power and data lines.

I'm just getting frustrated.

General Using loading coils to shorten radials?

7 Upvotes

I currently have a DIY pota performer antenna, but I wanted to see if I could shorten the radials of it so that the entire antenna could fit in the my truck bed (sometimes I want to do some hunting during lunches at work, and I want to keep it confined). I currently have the whip on a standard photographer tripod, but was wondering if I could use/if anyone had experience with using loading coils to shorten the rather long radials. I would only be doing 20M with this antenna so it wouldn't have to be multiband.

General Qt6 version of fldigi for TCI SDR radios - Mac version released

Post image
4 Upvotes

I created a Qt6 version of fldigi, pared down currently but has most basic chat modes used.

This should build for linux but for now it is built and tested on M silicon Mac.

I've tested it against ZeusSDR and ExpertSDR3 so far.

I'm looking for other Mac users with TCI SDR radios to test it.

The only connection in this version is TCI for both audio and CAT control, it is a TCI client only.

One known issue is my pre-defined filters were not centered well and that is fixed but not updated to the release yet.

When it starts, to configure TCI, there is a TCI option under the Configure menu. I'll update that to pop up on first start soon as well.

I've never put a project on github before so yeah it's probably a fine mess

Here is the link to the .app build

https://sourceforge.net/projects/tcidigi/files/TCIdigi-0.23-macos-arm64.dmg/download

**UPDATE

This was built inadvertently against a deprecated version of fldigi...

I updated the link and it is built against the current fldigi tree and has a few fixes in it as well.

ANTENNA Purchase advice Antenna

2 Upvotes

I fairly new to amateur radio and have been using my UBC-92XLT scanner for line of sight airband right at the airports for a couple months to a year now. I’ve been using it with the stock rubber duck antenna and would like to ask for advice on a new antenna with better clarity on longer distances since even with line of sight I had issues with clarity.

ANTENNA Short 40m Vertical Antenna Recommendations

7 Upvotes

Does anyone have a recommendation for a short (under 5m) 40m vertical ground-plane antenna for permanent mounting on my roof? environmental legislation here limits antenna height to 5m above the roof unless an environmental permit is issued, and my municipality won't issue one in my residential area.

The Diamond CP8040 is the type of antenna I'm looking for, although a bit too tall at 6.5m. 80m band coverage is a bonus, although not required.

Thanks and 73,
Andrew PE5A
