Recommended study material? in c/amateur_radio@sh.itjust.works
[–] martin77@sh.itjust.works 2 points 1 week ago

Since you say you are US based you have 2 options

  • Simply passing in which case you can use hamstudy and associate answers to questions you don't understand.
  • Study, learn and understand the material : refer to the W4EEY channel on YouTube. Best content for the US licence.
Boost for reddit has now truly 100% died. Hello Lemmy! in c/boostforlemmy@lemmy.world

I bought Boost for Lemmy on day 1 and come once in a while but let's be honest people haven't migrated off Reddit (and likely never will ) so outside of a few very specific subs there is barely anything for me to read over here...

Raspberry Pi 5 – Raspberry Pi in c/amateur_radio@sh.itjust.works
[–] martin77@sh.itjust.works 2 points 2 years ago

Considering the price increase and unless you really need the GPIO I don't know why you would pick this over a second hand 1L form factor PC... I love raspberry pi but since I picked up an m720q with an i5-9500t and 64 Gb of Ram that can run very intensive tasks such as a 16 slices CW/FT8/WSPR plus WebSDR and several others in Windows 11 and Linux VM or Container under proxmox they have become a very tough sell. Not to mention the way the Raspberry pi foundation treated the maker community during COVID.

It still works great: all you have to do is to create a dummy community on Reddit and set it private.

I didn't see any ad and actually had to search for the option to pay. Finally found it and was happy to 125 THB to support the developer.

Does drywall eat signals? in c/amateur_radio@sh.itjust.works

Yes any obstacle will affect performance. Indoor antennas especially when using a compromise antenna like yours and QRP power is never a very fun exercise.

Si OP peut trouver quelqu'un pour lui ramener un T480 des états unis alors qu'il n'hésite pas : j'ai acheté un T480 il y a quelques moins pour 180 USD et il y en a des centaines a ce prix là sur eBay.

I usually try to support the local association wherever I leave. I have been a member of the REF in France, the DARC in Germany, the SARTS in Singapore and now RATS in Thailand. I don't really care for what they offer ( indeed I don't even applied for a reciprocal Thai callsign) but it's more so they have the funds to support and lobby for our bands. They are the voice of our hobby against telcos who are willing to pay billions in fees for our frequencies especially in the SHF and up landscape. If no one defends those bands, we can say bye bye to anything above 70cm within a couple of years.

With over 600 members c/amateur_radio isn't a small community. There is however very little traffic and even less engagement. What kind of content are you actually looking for here ?

Using DAB / DAB+ to check propagation with Welle.io (sh.itjust.works)

With DAB and DAB+ now widely available in Europe it's really easy to leverage it to check propagation. Every couple of hours I run a quick scan accross all of the multiplexer to see the ones I pick up. DAB / DAB+ in Europe operates mostly on VHF Band III between 173-230 MHz making it a good indicator about the propagation on 2m. I use welle.io as a software with an RTL-SDR v3 screen and a simple home made vertical dipole cut for 2m and that's plenty to catch stations about 200 Km away on a daily basis.
