A feature production by the Hammared Ham! A cool little Tube QRP transmitter sent to me by N0XE (Jim), built by AF7RP (John). a 3watt CW special. Crystal frequency selected 7.115Mhz. The band was a bit rough, my receiver was drifting, however I was able to make many contacts all over the country! Big fun, yes it takes work but the result is well worth it. I plan to shoot more of these type videos soon. Listen on my standby frequency, maybe you will be the next heard on KZfaq! 73's de n6tlu.From the builder This is the magazine I originally used to build my first 6AQ5 tx.

Neat stuff! I have a bunch of QRP stuff; Heathkit, Ten-Tec, MFJ, and some of the newer QCX radios; a lot of fun. But then too, I do operate QRO when required. CU on 7.115. 73, de Karl, KO8S, Warren, MI

WOW! I'm really impressed with the distance you are getting on 3 watts. The bell is a great idea. Good to see the hammered ham again.

When I was 14 and my parents had no extra money I had to build my first ham radio some 40 years ago. 12AT7 feeding into 6L6. All from old TV sets. Thanks for the retro.

Great! I just bought a NC-183, and it's working. the Prior silent Key owner used it for CW only, and that is what I plan to use it for this fall, as I start learning CW. I have only been a Ham for a year, got into the Hobby at age 58, I am a General, but I admitt, I'm as Green as they come in Amatuer radio, but I like the old stuff and want to learn Cw. Enjoyed your ;video much, I think I will be asking you questions for sure, hopefully on the air. My transmitter will be a 1948 Wolf Special Transmitter, 80 and 40M,

Thank Terry for doing this. I think the tone on TX is due to the drift of the RX and probably some small front end overload as when I used it here the tone always sounded very good with no chirp or whoop but of course the quality of crystal also plays a big part in that, all the best to you and the family and stay safe Thanks again!! 73 Jim N0XE

From Leo: Fun memory. I remember building a similar transmitter in about 1968 from a plan in the ARRL handbook. Mine did not use a 6aq5 . It was an octal socket tube, built breadboard style on a piece of 2 x 10 board with terminal strips . Ran on a folded dipole stapled to the rafters inside the attic. Luckily the house was 35 feet long so I could full wave 20 meters if I folded. Flat key days.

@mrradio2187 3 жыл бұрын

I constructed the single tube CW xmtr in 1975 from the schematic in the 70'ish ARRL handbook, I think the tube was a 6AQ5 but I'm not sure. What I do remember was having a lot of fun working stations all over the US on 40 meters with just a dipole and my Hammarlund HQ-170 rcvr. I remember the rig had a clean note and at that time band propagation was good so 599 signal reports were plentiful.

Back in the day that was the way it was, you tuned your ear for the cw note you wanted to work and still you could copy adjacent signals at the same time with some practice. It was kind of like a party line except everybody was rockbound and a few kc off of each other. Great fun!

My Hammarlund from the 1950s has 500Hz selectivity. Before the days of crystal receivers. Also the original regen receivers could tune very sharply albeit with slightly wider skirts.

I once did a station in oaklahoma with 100 mw going into 3 element Wilson 10-11 meters. I don't remember the frequency or band, just know it was SSB. In all fairness I was using 40 watts for the initial contact. Decided to see if I do with less than a watt.

Not trying to be negative, just curious - you're using a crystal, yet you have chirp. Power supply issue? Unstable parts in the oscillator? Thoughts? Cool video and enjoyed seeing that old homebrew get the job done.

Hello, The chirp was mostly generated by my receiver drift and input overload. The TX note itself is fine

@timthompson468 3 жыл бұрын

That’s pretty cool. Is an FCC license required at that power level? I assume so. I have the Radiotelephone Operator’s license, but I don’t remember if that allows me to do ham transmissions. As I recall a different license is required for hams. I’ve been trying to learn Morse code, but it’s harder than I thought. I memorized all the alphabet codes, but I can’t write down the letters fast enough to keep up with code at a reasonable speed. I like your idea of videos with CW “conversations.” That would be a useful Morse code study aid for me.

@waynethompson8416 3 жыл бұрын

I think you may already know that the requirement to show proficiency in CW to get an Amateur Radio license was dropped, but if you didn't know, now you do. Something that made a lot of sense to me concerning learning how to copy CW was to NOT listen for every letter and try to write it down. The reasoning is that it is like expecting someone to spell every word they speak as they talk to you when you do that. Instead, you learn entire words. I wish you the very best in earning your license!!! 73! WB4RHA By the way, Tim, check out my website www.qsl.net/wb4rha Let me know what you think of it.

I'm pretty sure you can use any frequency at power levels 100 milliwatts and below. That is to allow for RF signal generators and so forth that might "leak" a bit into the environment. I had an RF signal generator that had a modulation input. Connected to a long wire antenna it had a range of about one city block :-) There's special ways to write letters that use fewer strokes. a "K" for instance is sometimes just "
