#145MHz
For the curious, this is my #ISS #SSTV setup. RX: A homebrew 145Mhz Moxon and an Icom ID-51. Decode: Lenovo Thinkpad running #Ubuntu Linux and QSSTV software

Playing with the new SDRPlay. 137Mhz on a 145Mhz antenna, no preamp, and it received quite a nice image. #NOAA #satellite #niceweather #hamradio

Vysielacka s rozsahom na 145mhz, dobra antena, výhľad. Alebo niekde na webu sa tiez da počúvať

Those dual band walkie talkies 145MHz/430MHz work great outdoors and on hilltops. There may be repeaters in your area to help extend range...

The #Baofeng UV-5R mini is a nice looking handheld #radio #transceiver but the stock #antenna is worthless on #2m #145MHz
This Retevis RHD-701 works much better.

Need to drop it from 146mhz into satellite band 145mhz

I found most of them in amateur.txt. Orbitron says they are all on 145MHz. Where do you find the frequencies?

SatNOGS地上局向けに, 430MHz帯用に続いて144MHz帯(2mバンド)用のQFHアンテナを製作いたしました!📡🛰
LiteVNAによる測定では, 共振周波数は139MHzと若干低めとなっていますが, SWRが2以下の帯域は135MHz~145MHzとなっており受信用アンテナとして比較的良好な特性を得られています.
また, スミスチャート上の軌跡より円偏波アンテナの特徴である複素共振特性を有していることも伺えます.

145Mhzと言うのは呼び出しに使う周波数ですw

Meine #iaru 145MHz-Contest-Teilnahme von heute. Mit 40W und guten Bedingungen in 5 Stunden* 38 Verbingungen geschafft. Und, sehr crazy: eine davon bis nach England, 817 km weit!
Insgesamt 8 Länder, 20 Großfelder und ein Schnitt von 246km/QSO.

*davon ca. 3,5 […]

Raspberry Pi transmitting 145MHz SSTV with GPIO PWM on a Raspberry Pi at the @G3KMI Stand at the SUSU Bunfight today!
