Thanks a million. Varactor. Many times working on vintage radios. Cold solder Joints.

Thanks for the PDF. I was always interested what's inside my favorite Desk Mic. My opinion best Communication Desk Microphone ever made. Curious: What is Q1 ? Looked at symbol charts. A field effect transistor ? Looks like 2N3219 ? ZN3219 ? Best John

Neglected to check LSB before starting a Re-Cap & Mods. I used it in my car for a few months AM. I received it with lower channel mods. 10,000uf Elna - PSU board. I changed out all the large caps to new Japanese. Played with the Audio. Decided to remove the resistor & reconnect the clipper...

Lot of good Info in your Posts. LSB not working on my Trc 457. USB AM Ok. Any clues you can suggest to me. Thanks in advance. Best John

Thanks, I never installed Adobe/Flash on IE. Forgot. I just open in Chrome ! Now to find an open source Utub down-loader . Might try the mod today on a Trc457. But maybe to morrow. Its time consuming a Re-Cap. Then removing an old lower channel mod. Reconnect the NB switch.Then installing a...

Ahh the 357 Post is just a black rectangle. Sooo. I am in the dark as to this "Fet" change. And which FET ? & to what later Fet Part #? The broad-banding mod I am aware of. R43-L4 & RC Mods .Okay how about an explanation. Shotky's ? Best

It is an old Post. I wanted to share a simple installation Mod for the receive. I had a Ureka moment when re-capping/repairing my CP2000B. The CPI Base/Mobile It uses the 8 pole SSB filter for both AM & SSB. The 858 Chassis uses 1 Monolithic 7.8MHZ crystal filter on AM & a 7.8 MHZ I...

Okay, Looked at the FC 347 schematic on CB Tricks. It appears that I have to add 6 x 22K resistors and two more leads to the cost effective FleaBay counter. This will cover USB and LSB. I found this Mod in an archive for installing an early version FC347 to a Cobra 139XLR...

Exactly ! That is why I am Buying 500 pcs Smiles. However; I did post somewhere a generic circuit using a pair of PNP low noise hygain transistors in parralel. Will try it eventually with 2 x 2sc1730L. If I run into issues. Will learn how to use "Spice" to model the circuit and give me the...

Well. I realized I confused a PNP version Data Sheet similar to BF763. BF763 has an NF of 5DB at 800MHZ. Most likely will not due. All that is left- is to investigate SMD PNP transistors that are of newer design. I have an opportyunity to get 500 pcs of 2sc1730L cheap. I will just buy it...

Yup. They can be set with offsets. They also require a case. If you are going to have them external. I used scraps of metal studs to make a quick case with Zippys. You can use tin Cans. Need to know where to hook it up. Value of coupling capacitor/resistor. Best John

I have a Uniden Washington base with a Digi-Scan. Noisy and susectible to Splash big time. Yes. What I am trying to do is find a transistor with low noise and high gain superior to the 2sc1730L in a TO-92 package if possible. Might not be. Now that you mention "8719" chassis. Today will...

Ah Ha Ha ! Okay. What about BF763 2GH Even higher gain ! 800 MHZ 3.9 DB NF 200 MHZ 2.3 DB NF Seems NF is going down as the frequency gets closer to 27MHZ frequency !!! 27MHZ ? Thanks for the reply. Any pointers in installing a frequency counter unto the 858 Chassis 2nd generation ?

Maybe "399" might be kind enouph to impart his experience and knowledge ! I have seen them on Ebay. Just missed out again on another one. Robyn 520D with counter installed. Couldn't afford to bid on it. Anyways I didn't like the way the Radio looked Not the digiscan. Just a frequency...

Well. The Truth is it became ShitShack. Corporate Geniuses decided to put one on every corner. They figured they could capitilize on the Brand fallowing offering over priced electronics. They moved away from the hobbyist and tried to become a "Specialty Retailer". Of "High End" items. I have...

Ok its been awhile. Im like a coiled Spring. Did you check them out these 1730's ? Best John

Looking for amplifier schematic . Parts list. Also if possible the impedance of the original ceramic element. Turner M+3. I have two. Both; the cartridges are beyond repair. Would like to rebuild them with other cartridges. Best John
