@viktor.saenko6819:matrix.org@viktor.saenko6819:matrix.org

seems like this room is dead, still I want to ask something

what's the best sdr for playing with WSPR-like protocols? rx and tx

09:22:40
@zcbxn:darc.deNorbert DL8LAQYou can use any SDR-trx for WSPR!09:46:04

thanks, but what is the best price/perf-wise?
10:12:53
@zcbxn:darc.deNorbert DL8LAQI can‘t make a good advice. There are so many different SDR-Radios on the market, that I don‘t know of. I use some not so cheap radios.10:53:50

@z4non:matrix.orgz4nonhi all:) im planning on installing rtl-sdr into a lil briefcase that has 10" display and a pi4 - wanting to keep it lightweight and portable i figured i just make a hole for the rt-sdr v4 and place an angled sma adapter on the side of it; with a small "gsm-like" antenna pointing up on the right side..i can share pics if this peeks anyone's interest. I was just hoping someone could help me find what adapter and antenna i need. Coz i bought the diopolantenna taht came with the rtl-sdr v4 also - but the sma extender dat came with didnt help much since the sdr has sma-female. 16:53:39
@al9d:pikaviestin.fiAL9Dantenna depends on use case. but if you just want a short sma male-female jumper then something like this? https://www.amazon.com/DZS-Elec-Connecting-Frequency-Connector/dp/B06XVR6TV6/ref=sr_1_817:03:27
@al9d:pikaviestin.fiAL9DBUT it might be better, depending on various factors to just use a short USB cable to stick the sdr dongle's sma female out of the enclosure17:04:39
@z4non:matrix.orgz4nonOk thanks. I think i can use those sma extenders. And it would be easier to have it outside of the case/box indeed. I may do that if i dont find a nice small sma-male antenna i can use, i.e "plug n play". Use case btw is just FM recieveer out on camping, i guess that is shortwave, i could actually also need some help with setting my dongle up so it doesnt cause any interference. But i will check with local radio clubs also because of perhaps some legal restrictions, for which i will take whatever license is needed.17:10:17
@z4non:matrix.orgz4nonThis one is supposedly a sma-male? https://www.electrokit.com/antenn-gsm-sma17:11:40
@z4non:matrix.orgz4nonBut since i am clueless rly, i dont know if this antenna is good for my usage. 17:12:55
@z4non:matrix.orgz4non * This one is supposedly a sma-male? edit; if im not reading it wrong. https://www.electrokit.com/antenn-gsm-sma17:13:57
@al9d:pikaviestin.fiAL9Dit isn't really since it will be cut for a much shorter wavelength17:17:07
@al9d:pikaviestin.fiAL9Dare you in .se?17:17:20
@z4non:matrix.orgz4nonyes17:17:25
@al9d:pikaviestin.fiAL9DRTL-SDR is receive-only so no worries about interference or licenses there17:19:20
@z4non:matrix.orgz4nonoh ok nice to know:)17:19:34
@al9d:pikaviestin.fiAL9DI guess you don't want to use the included telescoping dipole because it is too big and awkward?17:21:46
