Thank you for this wonderful series on the ARC 5. It's too bad RUclips wasn't available in the mid 50's when I was 12 years old and acquired my first receiver. Best regards, 73, de Mick - WB4LSS
Back in the late 60's when i was a ham i used and arc5 . I just restore old radios now but Im 67 years old now and have two ARC 5's I am playing with this is a great series all the information i have forgotten over the years. Cheap and dirty bfo that's great.
Enjoying your channel immensely, and your videos on the ARC-5 sets are invaluable. Just discovered you, and am having a blast catching up on all your videos. These videos are a great asset, thank you so much.
Yes Doug, I was moving too fast with this video to get into the details and explain the circuits. You have a GRC-9. Nice radio and one with a wide bandwidth! Any of the methods shown would work but I would go for a 455 or 456 kHz ceramic resonator or filter and sneak it in between the mixer and first IF stage.
I've really enjoyed your videos about the commands sets. I really like the respect that you show the old rigs. I have a couple of transmitters that were given to me years ago (1979). One is 3-4 Mhz and the other is 4-5.3 Mhz according to the dial face. They were in bad shape when I got them and at the time I didn't have the free time it would take to clean them up and evaluate them. I'm glad that I kept them. 73 NE5U
Great series on the Command sets. I put a crystal filter in a spare IF transformer and it really works well. I bought a 2832 KHz crystal from Mouser for about a dollar. It does make a for a nice cw receiver. Thanks for sharing your clever idea.
Great video. I love the xtal filter info and i'm going to look thru my stash for 2830 kHz rocks. A few decades back I tried another way to use a crystal: as a cathode bypass. Didn't work at all, I think because the cathode resistor was too low a value and so undid the crystal's effect; I thought maybe a choke in series with the cathode resistor would solve this, but never got around to trying it.
Thanks for this video. I have a similar project I've wanted to improve the selectivity. A GRC/9Y back pack receiver transmitter. You presented a lot of information here quickly. Can you direct me where to find more information on Q multipliers and crystal filters for vintage circuits. I enjoyed the series. Great job.
I'm working on a command receiver right now, the Navy equivalent of the R-25 (1.5-3 Mc). Strangely enough or maybe this is normal, there does not appear to be a limit to how far you can spin the dial, it will keep going while the variable stays in place. Which is not good to do. Is there a limit in how far you can spin the dial? I'm wondering if someone has removed this to get a few extra Kc out of the receiver.
Hi, Love the videos, really informative. Have an BC453, 150Khz-> 550Khz, what needs to be changed convert to 3Mhz->6Mhz, is it do-able? Regards Peter G8WGD (UK)
Peter, it is doable because the command sets are similar and some parts are common. But to do it you would first start with a 3-6 MHz Command set as a a donor. But if you had a 3-6 MHz command set why would you want to convert the 150-550 kHz job in the first place? I would just use a simple crystal external converter and tune the command set as an IF.

This is a great series! Thank you for the time & effort you've put into this.
Hi Mike,
thanks for your efforts and presentation of another v.good video about the command sets. I'm enjoying and learning lots.

Great job, really enjoyed it. The crystal filter is a great idea.
Thanks!
