However, on SSB I am hearing distortion on my transmitted signals. I even increased the bias setting to see if there was any change. They did not work. A transistor is a semiconductor device used to amplify and switch electronic signals and electrical power. Because the controlled output power can be higher than the controlling input power, a transistor can amplify a signal.

I’ve got some ‘duff’ ones from Eleflow just like Cliff did for a TS – mine won’t fit!!!!! And their buyer protection seems to be too good not to give them a try.

K2CBMay 26, Sadly, it’s not just the TS dataxheet are used in, there are many other rigs as well, I am certain if you come across any NEW ones they will be fake or vatasheet call them what you will I no longer work on TS’s needing 2SC’s replaced. I still have them and the packet here I purchased 2SCs from this same broker a few years back with good results, so I did not hesitate to try him again.

Fortunately my payments were quickly and fully refunded in both cases. Fluke, Mikroelektronika, Knipex and Logitech. A small current entering the base is amplified to produce a large collector and emitter current.


The last thing I can come up with is Eleflow. Same for a few other RF devices I measured. I am pretty sure a have a spare pair.

He explained how difficult is to find genuine transistors these days. Weazle66 is listed on their site as being an authorised distributer on E-Bay.

Collector – Base Voltage Vcbo. Comments 0 Write your comment. But I’ve seen that over the years with other Mitsubishi devices, such as the and devices.

Region Macedonia Kosovo Global. G3YROMay 26, They were shipped back and I never got a refund, they claimed never received.

So even though they look authentic in almost all aspects, I am now suspecting that they also may be knockoffs, albeit much better done than the Chinese AliExpress junk Any 2cs1972, comments, or suggestions? The first batch worked fine.

There are tell tale signs, Writing easily smudged off, lead out thinner than usual, very shiny metal tabs that look different, the gains on the ones I have is 85 way on the high side I reckon. All 6 I received measure an HFE of 2. That is just gotta be a logical answer Roger.


K2CBApr 26, These two kinds of charge carriers are characteristic of the two kinds of doped semiconductor material. NPN is one of the two types of bipolar transistors, consisting of a layer of P-doped semiconductor the “base” between two N-doped layers.

Anyway, I installed a pair into the TS Until I get this sorted I will never order from Eleflow again nor would I recommend them to anyone. Lettering easily smudged as if wet.

The radio makes full power on all bands, and the power control is right on the money from w.

In contrast, unipolar transistors such as the field-effect transistors have only one kind of charge carrier. The bias pot was pretty much within spec ma before I performed the adjustment.

A gain of 2 sounds pretty bad to me, I would estimate a gain of around 30 might be typical on the best of devices, this could be the answer to the distortion at low power. Next, I decided to perform an HFE gain test on the devices received. G4COEApr 27, datasgeet Equipment for testing of medical equipment. As I said my Eleflow devices these ‘have’ the hallmarks of fakes or very datassheet copies.
