In aligning FM radios, having a means of producing a stable, accurate and clean signal in the FM band of frequencies is very useful. This applies to both modern receivers and tube radios, but obviously more so in the former.<br />I have been looking for (drooling over) a good solution for this, but the costs are usually higher than I can justify for the amount of use I'd be giving it.<br />I came across the ELV website in my search, and was pleased to find this option, which seemed to tick all the boxes: It was small, modern, very accurate, and most of all, reasonably priced. Here is the product link:<br /><a href="https://de.elv.com/elv-hq-stereo-ukw-pruefgenerator-mit-oled-display-sup3-komplettbausatz-143310" target="_blank" rel="nofollow">https://de.elv.com/elv-hq-stereo-ukw-pruefgenerator-mit-oled-display-sup3-komplettbausatz-143310</a><br />This unit comes as a kit that is almost completely pre-built as it uses SMD components. You basically need to put it together, and that too appealed to me. <br />I hope you enjoy this build video, and I'm sure you'll be seeing much more of the unit in operation in my future videos.<br />Enjoy.<br /><br />TimeStamps<br />00:00 ELV SUB3 FM stereo test generator with PC control via USB.<br />01:20 Device characteristics.<br />03:47 The build.<br />14:06 Operation.<br />16:00 PC software control.<br />21:50 Closing.<br /><br />You can now support the channel:<br /><a href="https://www.patreon.com/mcaldeira" target="_blank" rel="nofollow">https://www.patreon.com/mcaldeira</a><br /><a href="https://paypal.me/macaldeira" target="_blank" rel="nofollow">https://paypal.me/macaldeira</a><br /><br />#tuberadios #antiqueradio #radiorestoration<br /><br />______HUNDREDS OF OTHER VIDEOS TO CHOOSE FROM_____<br />DIY TEST GEAR: The title says it all:<br /><a href="https://www.youtube.com/watch?v=7buNHf6HoDw&list=PLy5M_tA9ux7KkjmWX0I0zNocg6NF33EfL" target="_blank" rel="nofollow">https://www.youtube.com/watch?v=7buNHf6HoDw&list=PLy5M_tA9ux7KkjmWX0I0zNocg6NF33EfL</a><br /><br />RESTORATION BUILDING BLOCKS: A series of videos showing detailed steps used the restoration process of tube equipment:<br /><a href="https://www.youtube.com/watch?v=7xvTGd4ysRE&list=PLy5M_tA9ux7JSYx8z2mw303vx287LHpzf" target="_blank" rel="nofollow">https://www.youtube.com/watch?v=7xvTGd4ysRE&list=PLy5M_tA9ux7JSYx8z2mw303vx287LHpzf</a><br /><br />HowTo's: Various videos on some simple techniques and projects:<br /><a href="https://www.youtube.com/watch?v=lgr-J_D6pSU&list=PLy5M_tA9ux7K3B77iUGyLPai3RIvJOrkO" target="_blank" rel="nofollow">https://www.youtube.com/watch?v=lgr-J_D6pSU&list=PLy5M_tA9ux7K3B77iUGyLPai3RIvJOrkO</a><br /><br />See also playlists on some other completed restoration projects.<br /><br />PHILIPS BX750A:<br /><a href="https://www.youtube.com/watch?v=i8U9Lteja5o&list=PLy5M_tA9ux7IG6XgctidGO0u0DeT3_CxF" target="_blank" rel="nofollow">https://www.youtube.com/watch?v=i8U9Lteja5o&list=PLy5M_tA9ux7IG6XgctidGO0u0DeT3_CxF</a><br /><br />TELEFUNKEN OPUS 2114:<br /><a href="https://www.youtube.com/watch?v=_HO2bjY5vuw&list=PLy5M_tA9ux7LhcZ9h9plfTFmjaM1mcifu" target="_blank" rel="nofollow">https://www.youtube.com/watch?v=_HO2bjY5vuw&list=PLy5M_tA9ux7LhcZ9h9plfTFmjaM1mcifu</a><br /><br />SABA UW-175-Z 3D:<br /><a href="https://www.youtube.com/watch?v=cca4i60ZLw4&list=PLy5M_tA9ux7IWL18nsrSf4RnjsuPjHC-p" target="_blank" rel="nofollow">https://www.youtube.com/watch?v=cca4i60ZLw4&list=PLy5M_tA9ux7IWL18nsrSf4RnjsuPjHC-p</a><br /><br />GRUNDIG 1070:<br /><a href="https://www.youtube.com/watch?v=i4J5l0fwhko&list=PLy5M_tA9ux7JgnyYPRWOK763aJ8bg3iCI" target="_blank" rel="nofollow">https://www.youtube.com/watch?v=i4J5l0fwhko&list=PLy5M_tA9ux7JgnyYPRWOK763aJ8bg3iCI</a><br /><br />SCHAUB-LORENZ GOLDY 58 type 3020:<br /><a href="https://www.youtube.com/watch?v=RSbt7qVed78&list=PLy5M_tA9ux7IBse5G--Kl89SPS9sATXfZ" target="_blank" rel="nofollow">https://www.youtube.com/watch?v=RSbt7qVed78&list=PLy5M_tA9ux7IBse5G--Kl89SPS9sATXfZ</a><br /><br />BUSH VHF64:<br /><a href="https://www.youtube.com/watch?v=U--6JymkQ1M&list=PLy5M_tA9ux7KsvN5M48cX6cxN4jSz0s3X" target="_blank" rel="nofollow">https://www.youtube.com/watch?v=U--6JymkQ1M&list=PLy5M_tA9ux7KsvN5M48cX6cxN4jSz0s3X</a><br /><br />GRUNDIG 3060A:<br /><a href="https://www.youtube.com/watch?v=7x2sK2GSYeE&list=PLy5M_tA9ux7L8e9h8lrHGREPqcgWO-YQm" target="_blank" rel="nofollow">https://www.youtube.com/watch?v=7x2sK2GSYeE&list=PLy5M_tA9ux7L8e9h8lrHGREPqcgWO-YQm</a><br /><br />TELEFUNKEN OPERETTE 8:<br /><a href="https://www.youtube.com/watch?v=5IsACM0mPzs&list=PLy5M_tA9ux7K3SXDv8Hu4uAyl1O7NE5dc" target="_blank" rel="nofollow">https://www.youtube.com/watch?v=5IsACM0mPzs&list=PLy5M_tA9ux7K3SXDv8Hu4uAyl1O7NE5dc</a><br /><br />GRAETZ SUPER 171W:<br /><a href="https://www.youtube.com/watch?v=MhG-CH0gqm4&lis" target="_blank" rel="nofollow">https://www.youtube.com/watch?v=MhG-CH0gqm4&lis</a><br />...<br /><a href="https://www.youtube.com/watch?v=gUmdCfA8EBw" target="_blank" rel="nofollow">https://www.youtube.com/watch?v=gUmdCfA8EBw</a>
