Bought one of these and took it out today, made a random wire antenna with 16g speaker wire onsite. Used my telescoping mast and made a 211 mile contact on 40m with it, my signal was 5x9. Very impressed with it so far!

Hi matey. I have produced a video how to get the external microphone to work. It's in my playlist. It's a matter of swopping a couple of wires over inside microphone. Cheers from old George PS I don't think it's for cat control but firmware update only.

Great Vid. Just curious... Did you change the volume to 11 for a particular reason other than to make it louder? Such as a nod to something in the past?

Receive audio was actually quite decent. Would be interested to see an A to B comparison with another HF radio on RX.

Hooked mine up in my kitchen today on a whim, ran the coax cable out my back door and literally tossed my homemade speaker wire random antenna out in the yard only putting the end of it up on a table umbrella on my back deck, probably 8 feet above ground level. Turned it on and heard a lighthouse on the air activation from Lake Michigan, put out my call and he came back, I had to repeat my call 4 or 5 times phonetically for him to get it all, but he did get it. Amazing for such a mediocre attempt at erecting a simple homemade antenna. Heard many other stations across the band even from europe. These things are amazing. 5 watts, imagine if I had the antenna set up favorably??

how do you measure SWR on the radio?

@PhilRookemusic-educator 3 ай бұрын

Great video thanks - I just ordered one of these - $27 AUD. I thought to myself, "I've got nothing to lose for $27" but your video has given me great confidence to experiment with TX audio and see what it can do. As you said - a great little radio to put in the backpack with a simple long wire and you can throw it in a tree and try for a few contacts.

@valetech8751 Ай бұрын

which one exactly did you buy for 27 AUD?

@PhilRookemusic-educator Ай бұрын

@@valetech8751 It was advertised on Banggood for $27 AUD which I thought was odd. They showed the radio and described the radio but I only received the microphone and very oddly a travel adaptor for the power supply which I also did not receive. I only lost $27 AUD but lesson learned. If I do fork out $200 AUD, it won;t be with Banggood, I'll found a more reputable supplier.

@pauls8456 Жыл бұрын

How big is the battery, how much current does it require to operate, what was the non distorting power output on each band, how much does it weigh, and the all important qu - what is the chance that the one I buy will be anything like the one you bought?

Do you know what the UART port is for? Can you grab the IQ and use SDR software?

@DavidLopez-bz4rj Жыл бұрын

No 160 meters, doesnt have filters... Pa Bias Min = 0 Tx drive at least 4 with internal mic. Pa Bias Max depends on voltage on Irf510, never over 2.7. Use the best SWR, or power will go down. UART works with TTL, program firmware with USBisp oR USBasp or Arduino programmer. I/Q can be taken from chip to use it as an SDR

@Centar1964 5 ай бұрын

I have it, works perfect for digital modes and CW but the TX voice quality suffers on SSB from distortion. Audio from speaker is good. I use it for FT8 and JS8CALL and have made hundreds of contacts up to 7000 kms away with nothing more than a random wire and tuner. Backlight off option doesn't work (backlight always on) and there is no charge or battery level indicators and the included mic is garbage. Battery life is long (big battery). You can select 160 and 6 meters but they don't work. There is 9 working bands not 8. Power is best on 40 and 20 meters (10 watts) and it doesn't get warm. It does get warm on frequencies higher than 14 mhz and power output drops significantly.

@RosssRoyce Жыл бұрын

Why people say “seek you 40” when those who listen will obviously will be tuned to the 40m??? It’s not like some harmonic will transmit them to the 80m and the 20m as well so he’d only want response from the 40m listeners. I find ridiculous, unless I’m missing something?

@4youian Жыл бұрын

I guess it's to extend the call. Also some people say ...and listening. Well you just called CQ, what else would you be doing? If i want to extend the call i just say my callsign a couple of extra times. Which is more useful if conditions are poor.

@jiriculak6115 Жыл бұрын

Nope. Often CQ on 7100 results in 2nd harmonics on 14200! So it’s just a habit from old times when harmonic suppression wasn’t at its best. 73

@MarkPentler Жыл бұрын

Anyone tuning has more chance of seeing your signal or hearing your voice the longer your CQ call is. So it's just to give something else to say, really.

We used to run 4 or more radios on field days, people calling out the band was helpful when you have multiple bands going on at once, also it gives you something to say to make the transmission longer.
