Looking for a reasonable microwave kit

QUESTION

Been pondering getting into the microwave scene here in California… in normal times I’d go hit one of the clubs for more info, but figured I’d ask the Reddit crew first for suggestions on a reasonable microwave kits… I’m a midrange builder, I’d be buying in pairs to test/have someone to op with. I’m open on bands since I don’t have any experience above 1.2ghz (I’ve done a bunch of 1.2) it’s all uncharted to me.

Any thoughts?

Hey what band are you most interested in? Depends mostly on the activity in your region.

1.2 GHz can be received with some cheap SDR receivers, building a yagi is relatively easy. Also transmission is doable, e.g. with a PlutoSDR, but you need to take care of transmit amplification filtering and T/R switching. I did my only 23cm QSO that way.

More common is using a transverter, for instance http://q5signal.com/index.php?route=product/category&path=69

Lots of ideas here http://f1chf.free.fr/F5DQK

Another excellent resource is http://www.w1ghz.org

edit: 3cm is also an interesting band, I'm using a downeast microwave transverter that you cannot apparently buy anymore, but W1GHZ has excellent projects that are more recent. More mechanical work to get good performance (dish antenna mount and feed)

HSMM, also called broadband hamnet, is kinda bubbling along here. it uses Linksys access points and external dish antennas to link several nodes. I am also seeing some interesting activity with LoRa, which is “long range” mesh nets in the 900 MHz band. LoRa transceivers are interfaced to a computer running an app, powered by an 18650 battery, and can be gotten for $30/node. Check out YT with that search term. “Ham Radio Crash Course” josh is doing some stuff. My son in law knows this dude and he says Josh is the real deal. (Edit: fix autocorrect idiocy)
