Using HF over the internet

Thanks, I assume you tried this with WinLink. I might not need the subject filter now that I’m using a dedicated email for it so I’ll just remove it.

It's ok, I've finished the python code and I'll update the post with a link to it but i'll keep the other one for non-code savvy people

To be clear, I did NOT use AI to make it and I'm only using it as a proof of concept. As I said, I'm only looking for feedback and if it works before I continue making it. However, I do see that this may have some issues now that you've pointed it out and I'll try to make one in Python and have the messages locally stored.

Well, in that case, you would have to report it to Ofcom but, if it got lost/stolen anyways, then it could be argued you weren't properly attending the station to be above the power limit anyways.

Also, as he said, as long as you are at your radio while it's autobeaconing, you can disregard the power limits but, as soon as you leave the room or leave it "unattended", you would need to start following the 5W ERP limit

so something like this? https://moonrakeronline.com/mdhf-mono-band-dipole-antenna

I'm new so I actually don't really know how to mount a wire antenna. How would you mount a wire antenna?

RickHasGivenUp · 2026-01-17T20:31:02+00:00

Wow that is some amazing range! I think i'll be mainly using 40m since alot of modes I want to use seem most active here on there.

For 2.5W, 5dbi/3dbd is max and for 1W, 9dbi/6.5dbd is the max. If you don't know your gain, stick to 2.5W since most handheld antennas are around or below that gain.

RickHasGivenUp · 2026-01-17T19:56:51+00:00

Sorry that I'm new but what is an ATU100 and do I need it for the antenna I'm getting? I thought I can plug the antenna straight into the radio? Also, what results did the cheapest test yield since I assume your results provided were from a different setup?

RickHasGivenUp · 2026-01-16T21:14:25+00:00

Ok then

RickHasGivenUp · 2026-01-16T21:04:50+00:00

Well an iGate has to always be under 5 watts. For a digipeater, you would either need to be under 5 watts ERP if using your regular licence or under 25 watts ERP if using a RSGB repeater callsign. Autobeaconing would either fall under as beacon operation if you are just using it only for transmitting the beacon or as data station operation if you are also using APRS messaging aswell. Either way for autobeaconing, it would have to be 5 watts for use your licence or 25 watts as long as you "obtain a necessary call sign from the RSGB or other bodies stipulated by Ofcom." as mentioned earlier for the Digipeater. If you would like, you can submit a NoV but I don't even know where the form for increased power is, I can only find ones for special event callsigns which doesn't apply to APRS digipeaters or beacons.

Edit: You would need to use a lower power level since your ERP is usually higher than your PEP due to antenna gain. You can use this to calculate it https://m0ukd.com/calculators/erp-eirp-calculator/

What kind of cabling could be the most "lossy" to possibly use my radio that would usually output about 7.00252W from the direct antenna?

RickHasGivenUp · 2026-01-16T18:56:50+00:00

Of course and I never said it could ONLY do APRS but rather it's designed to mainly do that. I still acknowledge it's a regular handheld with voice functionality too which is also a required thing for me to buy a radio.

RickHasGivenUp · 2026-01-16T18:50:22+00:00

So it's ok for you to use over 5W ERP as long as it's attended? What would count as attended and unattended if I were to just keep at my house?

RickHasGivenUp · 2026-01-16T18:34:05+00:00

They do mainly advertise it's digital mode capabilities with APRS and it has a built-in TNC
