The GD-2015S has been amazing for me, incredibly weak spurs, okay-ish built-in stereo encoder and audio processor, but the reason I got it was because of the MPX input and it DELIVERS - Amazing sound quality and RDS with Stereo Tool/Omnia.9 PTN and Native Instruments Komplete Audio 1 Sound Card. I asked the seller to center it on 101 MHz and with a good-matched antenna, I was able to get 21W of output power on 101.0

Optimod pc1100 it for streaming mostly the Optimod 5500 would be better for you its rack mount but its fm version which means it has stereo generator and clipping clipping is the loudness for fm which the pc1100 does have or look if the still have the orban optimod 5501e which is a soundcard like the 1100 but designed for fm with that final clipper

I just went down the same street you did with this project. You have done a good job here! Do you happen to have any spectrum or oscilloscope captures of the actual stereo generator? I would love to see your results. I know this is an old project for you but it is so exactly what I am working on right now! Hope to hear from you, would love to compare notes.

Please do an update!!! If you could, experiment with the pre emphasis on narrowband 3khz. Curious how it does with that.

Hey man! Was wondering if you had a discord server?

I've watched this like five times and I zone out about 8-10 minutes in. I think you just waffled a bit too much. 30 watter with the QN8066? Which was that?

I'd be interested if you can make this perform better? I use this transmitter and run it for hours at a time. I've never heard any station bleeding. my antenna is a 5/8 wave 70 ft off ground with about 14 mile radius to the outer fringe. So any tweaking would be awesome to do. Always appreciate your videos thank you.

Awesome

Hey Spectraman. Have you had the opportunity to review and test the Fmuser FU-15B transmitter? would you have any info on the chip used in that unit? I see it on aliexpress. I'm also curious of the GD-2015 15 W transmitter on that site. It states "QN Chip" but not specific.

Esde usa o qn8066 sera

hello ,i need to know how many milli or micro hanry must be the coil? and can i use my 7 meters building to stand up the antenna? i have a powerless am transmitter, but need to build a linear on MW thanks 👃🏼

was this bought from aliexpress?

😮😮😮qn8066

do you know if exist a PCB with a QN8007 to be easy buy and get? on ebay maybe? or aliexpres¿

A linear power supply with heavy transformer maybe

Phase lock loop. PLL for people that dont know VCO voltage control oscillator. What about stereo encoder. .? Guess its included.

I'M SHOWING THIS TO DUMBROWSKI

I experimented a bit with MW antennas. When I grounded one ray of antenna - efficiency decreases.The counterweights must be next to the ground - but they must not contacting with ground: you will have losses.

Hi please can I discuss this with you

😮esse integrado ao lado do qn8027 e memoria ..

You did a very good in depth reverse engineering job I’m a old ham guy that has gone rouge LOL yes the eBay ones stay away from. We have a Camel RF from a guy in California that imported the Warner style transmitters puts better parts in that are known to give problems and tests for hours on a dummy load before shipping them out we have the 150 watt rack unit been running it for close to 10 years with no problems and is clean FM audio and does not drift ! The site has disappeared that we got it from was about $1200.00 back then . Do a spot on antennas we have about the last dominator from Norwalk electronics before they went out of business . It’s. .94 wave .

Awesome, I'm really happy that you're back! I'm planning on building an autonomous rig using a tiny car fm transmitter that actually has the QN8007 and a small 7w amplifier.

Yoooo welcome back!

Love your videos. Please make more.

Is it ok to just handle a 200 Watt RF transmitter (like your health)? You mean like those parts are from cellular base stations?

这种发射机都是卖假药的在用

regarding posting videos - don't sweat it pal. just remember, for every lifelong passion someone has, there was a small moment something caught their eye and they never looked away. it's hard to comprehend, but even someone as small as a little video here and there could profoundly impact someone.

glad to see you are back! please continue making videos about this FM transmitters and related stuff.

FINALLY BACK !!! ive been waiting for ages !!!! Dont leave us thslong.Can you test a PCS-Electronics SE version transmitter ?

Glad to see u back!!!

Glad to see you back. Next time you're gone that long, I at least expect a postcard. Interesting video, appreciate it

Hello, back in the 80,when the socialist f. Miterrand free the fm band we used MRF 317 for 100w amp. We couple two 100w with *ceramic microstrip couplers " too i was young but i remember these transistor produce sound during tuning the amp.

ATC100B ceramic capacitance, the use rd15 because heave to much used ones in bages :)

Hello sir, This is really a great video. Thank you

Maby the BLF if overdriven and makes this garbage on spectrum.

Couldn’t believe it when I saw your name in the video title. Welcome back! Your material is always interesting and well presented. Thanks for posting!

In two days I wanted to order the GD-2015S that you showed in the video, I thought it was good but what issues apart from the low power did you have with it? Is your unit defective or are all of them shipped this way? Should I order it or no?

Hey, great to see you back!! ( : Glad you're still pursuing this stuff! Thanks for sharing.

What about the current draw?

I haven't seen you for a long time. Regards

Dear master idol sir, do you have facebook page or fb account to messenger sir???

What is the operating frequency range and driving poeer input. The circuit diagram if you have not shown it in the video please. Ap2kd.

Good to see another video, thanks! - Hope all is OK!

This BLF177 was produced in week 42 of 1999. So it's been here a while :)

I am delighted you're back. Please can you include the indepth circuit diagram of the module ?

Glad you’re back!

Today I bought a new version of this transmitter on Aliexpress and it has IC BH1414K. With delivery to Russia it cost less than $100 in rubles. I will wait impatiently to receive it.

Very interesting Fm transmitters presentation . What could be happen if i use one of this Qn8007 transmitter in texas...with about 30 w..can i have issue with Fcc?

do you heave qn8007 exciter ? do you run RDS on it?

Radio master is so overvalued and rumors is not good about clear signal..
