- Hi. This is my first real tabletop shortwave / communications receiver.
It's a Yaesu FRG 7700.
It was manufactured in 1980 ( checked the serial number ). Which means it's 40 years old!
I got it for 1000SEK ( around 100usd / 100 euro / 90 pounds )
In this video I am mainly going through the main parts of the radio and performance.
Tomorrow I will hopefully buy the FRA 7700.
I can say that it's mostly better than the PL 660 overall.
Sorry for the text and my bad editing.
Here's the specifications.

I bought my FRG7700 when they first came out. I'll still using it.
Congratulations on the FRG7700. I have had mine for about 10 years now. I love this radio. Mine had a defective chip which made it jump frequencies but it was repaired and alignment and re-capped by Graham in the UK (radiochruncher). Now she's Dxing like never before. 73s Brian
Signal Hunter awesome!
You will enjoy using the 7700. I had one once & spent many pleasurable hours DX'ing.
Perfect old radio detected!
Yeah! I actually sold this and eventually bought a broken Kenwood TS-850, which I restored which is way, way more useful as an amateur radio operator, since it both transmits and receives. However it has got problems now and I don’t really know what the problem is, it creates a bunch of internal pops and crackles, almost as if a distant thunderstorm would be around.

@@sa6kod154 this is weird 🤔
Congratulations! 73 and good DX!
Thanks. This will be used a lot.
У меня такой же приемник, но принимает очень много радиостанций. Короткие волны и средние очень четко . Отличный приемник, у меня было много , но этот лучший. Принимает на кусок медной провода 0.3 мм. метров пять, прибитый к потолку .Украина .Киев.
73 from Mexico!
Thanks! 73 from west of Sweden!
Nice! Jätte bra video! Vad redigerade du videon i för något program?
Jag körde med ett program som vi använder i skolan. Väldigt simpelt, ej många funktioner. Men fungerar som en början. Nu är ju inte det här en slags blender fast den fungerar för simpla grejer. T.ex att klippa och lägga till text på sina videos.
Programmet är webbaserat och heter wevideo. wevideo.com
Ok. Tusen tack!
