You have un internet chassis to hold 8xAA, 3x18650, etc.

Also you can use a little Li-Po cell.

Here you are some pics of my Rig with lipo 5000mA and 3x18650

Morse Code / Re: Yaesu CW Filters
« on: July 13, 2018, 03:12:17 AM »
Yes, You got the right about It.
In fact, when I sold my 817, I bought a VHF rig plus the Elecraft because I want both bands.

With 817 you have all-in-one multi propose.

Anyway, if you become a cw fanatic, You need a high level performance rig than 817.
That's what its all about when getting a radio for preparedness. It's good for establishing contacts with low power drain, key factor. It's small, lightweight and ultraportable, but you still have HF VHF and UHF and all the modes you can wish for.

817 is a swiss army knife, has all but no good in nothing.

If you are not a ultra fan of CW, perhaps 817 runs fine for your propuse but in my case, the 99.9% of HF QSO are CW mode, I want more performance, selectivity and tools to make posible better contacts.

Please tell us more. I am considering selling my two years old and unused FT817ND.

Why do you consider it not a good platform for Morse code (CW)?

I bought for my 817 a 455khz filtre CW.
Works great and makes the rig runs well on cw Mode.

However 817/818 is not a good plattform for morse Code, in fact, I sold it and get a Elecraft K2.

Antennas / Re: Linked Dipole
« on: June 27, 2018, 08:36:12 AM »
Low noise in Rx maybe indicatethe antenna doesn't work properly, loops antennas is another concept, but dipoles and verticals yes, loud noise (S3-S4) could be fine.

Congrats for balun and linked dipole, It is a Big deal in the mountain.

I have one for 40/20m and works really well without swr

Never thought of that haha. The noise is really irritating. But it could be it was so noisy because of the global contest ongoing? (king of spain contest)

Antennas / Re: MFJ 971 vs LDG Z-817
« on: June 08, 2018, 01:31:21 PM »
LDG 817 is cheap (compared with Elecraft T1, p.e), is lightweight, fits perfect over the rig.

And for quick tunning, the best way is a auto tunner.

I like and enjoyed so much with Z-Match, transmatch and all manual tunners, but un this case, for 817, primary option Will be the LDG.

I am a big fan of MFJ tunners, I have two models and I ownered about four or five more.

Get the LDG atu for 817, Is the better choice.

I used a lot of tunners with the 817 but the best is the LDG

Technical Corner / Re: Modding MTR4b for 13.8 volts..... possible ?

You need a voltage regulator or a step down.

Example:

The problem is found a good variable Air capacitor at low price.

Do you have YouTube automatic subtitles turned on for language conversion? Assuming YouTube does that?

YT allows subtitles in the same lenguaje of the video.

Very nice. I did buy a spool of that yellow wire from SotaBeams, very light indeed. I wish they put a BNC connector on that PCB. SotaBeams has some cool stuff, like QRPGuys, very light for SOTA. I understood quite a bit of the Spanish; lots of words similar to French!

Gil.
Tnx Gil. Perhaps if I speak in catalŠn lenguage you are going to understand better.

Yes, QRPGUYS and Sotabeams make good and cheap gear for mountain radio.

Decathlon has fishing rods called "traveler" more compact than others. There is in 3,4,5 and 6m. 14,99Ä.

The last piece os too much thin, I retired It.

Spiderbeam HD 12m is a fabulous Rod for portable, not for hiking.

50$ for a stainless stick with a screw thread is quite cheeky
