I used this radio as a manpacked (3 guys) or in a landrover mobile till 1980 in the Royal Netherlands Marine Corps. Still got 3 of them. Regards PA5TH Tom

Great video Helge once again! I was lucky enough to purchase one of these from a radio fair in Finland. It came with the same full setup which you have on this video. From my own experience I might add that before firing up this please check the power supply and especially the hefty rubber power cable before connecting any voltages. Open up the MIL connectors on both ends and see the condition of the wiring insulation. My cable was pulversed from inside causing a potentially bad day. Luckily no over voltage to the 1.5 V heater line this time. Better put a couple of thick diodes to the 1.5V line before continuing. A living piace of radio history!

Love to see videos of this type. A lot of current day electronics techs. have no idea of how pre solid state components work. The radio gear was built to last forever at least physically. Capacitors especially electrolytic, wax paper were the weak links in the chain. Hats off to you sir for keeping this gear alive.

Bring back memories, I operated AN/GRC 106 when I was younger in the military. The problem then all 4 batteries were out of juice after 5 mins. Thanks for this very interesting video.

Leuke herinneringen aan deze AN/GRC-9. Heb deze set gehad in de jaren 90 (dacht de Telefunken uitvoering). Leuke verbindingen mee gemaakt door Europa, in morse cw en am. Was mijn eerste transceiver als amateur, en eerste verbinding mee gemaakt in morse. De meeste radio amateurs beginnen op 2 mtr. 145 mHz. Ook in am erg goed, amateur hier in buurt dacht dat ik met 100watt uitzond (15watt am). Jammer dat ik hem verkocht heb. Zat een typische geur aan wanneer je hem openmaakte.

I used to have the WW2 version, a BC1306. I had it mounted on my WW2 jeep! Nice to see it in operation!

Helge, like all of your videos this one is excellent; I have a GRC-10 set, good for 54-70Mhz.

Rod Moore typing...I carried one of these Angry 9 radios up and down many hills in Korea in 1951. We were a small group, 5 to 6 of us, spotting targets for Naval Gunfire, for the 1st, 2nd and 3 rd battalions of the First Marine Regiment. Have always been curious of the weight of the radio, I was just a grunt but could keep up with our Naval officer as we walked the hills looking for targets to radio back to the ship. Thirty to forty pounds?

Excellent Video!! Very Interesting indeed. I am a BIT OLD SCHOOL myself so I like video's like this. It is so good to see this OLD MILITARY RADIO find new life in the HAM RADIO HOBBY.. I will try to watch for future video's.

Thanks for showing. It must have brought back some old memories for you, I hope they were good memories.

Congratulations for the video. I have excellent memories of this RTX, because I made a connection of about 400 kilometers with 4 watts in AM.

Thank you Helge, in the '80s GRC9 thoug not used was still in the inventory of the Italian Army and I was trained on it as a young corporal of the Signal Corp, now I wish I had one to recall those times when I was much younger hi! 73 de IK5QLO

I also had training in this in 1976. Interesting to hear that you used this right up to the 80s.

I was trained on it in 1981, in the French army. We had the last ones, they were replaced shortly after with modern solid state radios. My sergeant told me therevwere used in Lebanon by French Army (under UN command) and there were heavily jammed by the Israelis. At this time, there were not sensitive and accurate, compared to modern radios. Edit : it is a radio "made in France" that is used here, btw.

Just got a 24 volt DY-105 for mine.And have a 60 amp 24 volt power supply coming next week hopefully get it on the air soon.Jim KB1PFL

Wau ... so much effort to get this into work ;) good job ! and super to see that it is still working.

Thanks for this Video! I´ve got the receiver, now I know how to trim it for max Sensitivity and Frequency accurance. So good.

I made qso in AM with this GRC9 over 800km. During daytime (late afternoon). Using the long-wire-antenna-setup as mentioned in the military manual. I have been told that it was possible to make contact over very long distances using CW. (Belgium to Kongo) 73's

Thanks for the interesting comment. I had training on this in my military service. AM mode on this is not very good on this receiver. 800 km is certainly possible, but not easy. Well done. CW is better.

@@LA6NCA I listened to the "opposite" (French) station using SSB (CW-mode) on the receiver-part, while I was transmitting in AM. He received me using his receiver in SSB and told me that I was readable quite well. My carrier was quite stable for such an "oldtimer" using VFO. I did not use the original mike but a self-made adapter plus a normal PTT-mike. I tested in the 80m-band. 73's

Excellent video, if the cover is latched to the radio set and the rubber gaskets are good. It will float in water. Mine I never tryed, but the gn-58 hand crank generator is cool!

Thank you infom 👍

Var det AN/PRC-77 vi brukte i kystartilleriet på slutten av 80-tallet, mon tro? Denne AN/GRC-9 er et mye større, tyngre og mer komplisert beist. Den har kanskje en mye kraftigere sender, og var neppe vanlig å ha med på patrulje med laget.

Ja du har rett. Denne stasjonen ble benyttet i KO i brigaden og bataljoner. Den ble også benyttet av fjernoppklarings folkene. Den kunne bli fraktet på pulk eller hest.

The cells in the bias battery aren't rechargable ones as far as i know. Not officially at least, lol. I replaced mine with some button cells i had sitting around. The original ones i removed from the little holder. They were very leaky.

Nice demonstration! Thanks.

Fantastic video! some one know a frequency to transmit in Am with this radios for example? I am too a collector to military radios I would like to transmit with my BC.375 for example and receive with my BC-312

I bought an Alco steam generator this morning, January 2023. It was last used 30 years ago & exhibited in a museum setting by the owner. The museum exhibition closed about 3 years ago. My hope is to get the boiler tested asap & then back in use. My B2 Spyset battery can then be charged & all put to use. I knew of this Alco for20 years or so & now I have it. I hope to demonstrate it charging Spyset batteries 🤞

Kann man damit Musik machen wenn man Reverb oder Delay über Klinke anschließt und irgendwie Sampels da durch schickt? Einen Klangfärbungseffekt den man nur durch so ein Gerät erziehlt um verzerrte Geräusche zu kreieren?

Yes, there are very special sounds, so it is possible.

What type of spray is he using to clean/lubricate? Is it an oil or an electronic connector cleaner? Thanks. Cheers!

Dear fellow Helge. I was looking for information about German army telecommunications at «D-day» when I visited your website. All I have to say is that: I was really impressed! Please accept my congratulations for the excellent work you have done, but also for your deep knowledge and dedication! Exploring your page I found yet another impressive piece of information for me. The "Fu MB 4" by Rohde & Schwarz codenamed Samos. (!!!???) Since I am a resident of the island of Samos, (Eastern Aegean sea), this information impressed me but also made me wonder... So I would ask you if you know why Fu MB 4 was given the code name «Samos», to write me a few words... Thank you for your time. Best regards from Samos. 73 de SV8CYV Vassilis

Igjen en fin video Helge. Gleder meg til neste. Når du skal gå mere i detalj må du få med at det er en bryter på mottakeren som må stilles avhengig av om du skal bruke høyttaler eller hodetelefon. 73 de LA5MT.

Interesant at se de gamle sendere og modtagere, bliver sjovt at se mere om dem 73 fra OZ3ACW😊

Her gik jeg og troede at GRC9 var en CW station. Jeg glæder mig til næste video fra dig. Best 73 fra OZ7NQ, Niels

Den fungerer selvfølgelig best på CW. På AM er mottakeren veldig bred. Den er det også på CW, men man hører signalet bedre.

Price??
