Ameco AC-1 CW QRP Transmitter and Homebrew Receiver

[N2RRAny]

Awesome vid! I'm inspired!

[K7AGE]

I used to have the AC-1 as a Novice back in the late 60s. I think I trashed it in the 70s sometime. Big mistake, these thing go for big bucks today. I really wished that you provided some narration to explain your station. K7AGE

This is the REAL amateur radio, aluminium and components can make something quite wonderful. A real achievement. Thank goodness someone still can do this. 73 M0VRK

@richardyingren Well said that man....

Nice set-up. Nothing gives the satisfaction like working someone on a home brew station you made!

Nice fist om. I have been a cw op for over 29 years now, and prefer straight key, but can use iambic as well as side swipers. CW forever!! 73''s Mac

Are you directly keying the cathode? If you are Dude, watch out! I suspect not because I hear a keying HV isolation relay that may also be doubling as a t/r relay. FB OM 73 DE WW2W Tony NYC

Constructive comments --or-- "Your Novice accent is showing":

1. NEVER tune up ON THE AIR, use a dummy load of some nature.

2. BEFORE TRANSMITTING, ALWAYS ask if a frequency is occupied by others. Simple sent QRL? a few times and LISTEN before transmitting.

3. CONGRATULATIONS on a very nice CW "fist" with well structured and sent CQ.

@w5lxg1

Some more "constructive" commentary:

Tuning up on the air is both a common practice and specifically allowed under Part 97 of the rules as a permitted type of one-way communication.

Many transmitters require adjustment with the antenna (not a dummy load) attached for a clean, chirp free signal.

This is a very nice looking and great sounding station.

That "Novice accent" comment is a cheap shot. Unless you meant that you are a Novice? Sorry, maybe I misunderstood.

are CW recievers only for morse code?

[SirPayne]

Nice rig. Would be cool if someone had answered to your call.

[GlobalAntennaWorks]

I wonder if you could tell me the output specifications of the power transformer on the AC-1.

Also if you know the specifications on the filter choke that would come in handy too.

Great video. I'd like to see another where you snag some sweet DX.

Hello and thanks for the comment! I have posted some useful links in the "more info" description for this video. There are many AC-1 replicas on the air. Visit these pages for more information on restoring an AC-1 or homebrewing your own version of one. 73, Jack WA6KYO

Tnx Colin! Stay tuned for some more QRP/Homebrew videos! 73, Jack

[mrjimbopalmer]

Nice setup. Is your homebrew receiver a regenerative type receiver?

[TechDemos]

Hi and tnx! My receiver is a simple direct conversion type with audio filters for added selectivity. It's basic, but actually works quite well and is extremely stable. I'll make a video of the receiver connected to a speaker when I get some time here. 73, Jack
