Yep. that was my first.
Chill, I had one of those. It worked pretty well. If I remember correctly, it ate up batteries, though.
Here was my first, wish I remembered what I did with her?

Still have mine.
Is that a Regency H604? I had one of those in the early 1980s. I made a couple of mods to it.My 1st still in use everyday.
No that is the replacement of the 604. That is a hx650 amazing how well it still receives I take it apart every so often and blow out the dust.Is that a Regency H604? I had one of those in the early 1980s. I made a couple of mods to it.
I changed a 0.22uF cap to 1uF in the squelch circuit to lengthen the RC time constant to get rid of the tendency to chatter at the threshold. The cap value could be as high as 2.2uF without issues with scanning however it created an annoyingly long squelch tail. A 1uF cap worked well. The design used an MC3357 FM IF chip, IIRC.
My other complaint was low audio output compared to good Part 90 handheld radios. This was fixed by adding a 2.2uF cap between pins 1 and 8 on the LM386 audio amp chip to increase the audio amp's voltage gain. Adding a cap between pins 1 and 8 is straight from the LM386 datasheet.
I got a LOT of use out of my H604 during the early 1980s. I later replaced it with a Regency HX1000 scanner in 1985. I loved the HX1000, even with the few quirks that it had. I also improved the audio output from the HX1000 too.
You know you are an old time scanner listener when you remember the mods you did to your early scanners.

I remember the HX650 but I never owned one. The HX1000 was my first programmable handheld scanner and I haven't owned a "rock bound" handheld scanner since.No that is the replacement of the 604. That is a hx650 amazing how well it still receives I take it apart every so often and blow out the dust.
I never did buy one of these early models but I sure do remember drooling over the radio shack catalogs wishing I could afford one. But at the time I was a newlywed and needed my money for more important things.This was my first ever. . . and only had to buy 2 crystals and got everything in my county. Those were the days.

Milt I also enjoyed NOAA Weather Radio since getting my patrolman Pro 1 as seen above. I also enjoyed NOAA Weather Radio to use to test various antennas on VHF High.You bragged to everybody that you could get the weather 24/7 without TV or commercial radio.
Now, thanks to the internet, everybody can do that but NOAA weather radio will always have a place in my heart.
Yep I remember this radio. Nice unit but the antenna kept popping out but if I remember it also had an antenna that was just a thin black wire I would assume about 15 in Long that you can hang outside of your pocket. Very cool, the rubber duck always popped out of the plug.This was my first ever. . . and only had to buy 2 crystals and got everything in my county. Those were the days.

I bought a PRO-2 in 1969 with a 45.98 crystal for New Britain (CT) PD. That was almost 2 weeks' salary if I remember correctly!
