Free technical support If datasheett goes wrong, we will be ready and willing to help! I purchased 2SCs from this same broker a few years back with good results, so I did not hesitate to try him again.

2SC1972 Source?

It sounds just like when the bias is improperly set too low on an amplifier, yet I triple checked to make sure it is set correctly in this case.

Anyway, I installed a pair into the TS The radio makes full power on all bands, and the power control is right on the money from w. They did not work.

These two kinds of charge carriers are characteristic of the two kinds of doped semiconductor material. I suspect the low HFE may be causing poor linearity or poor slow RF switching, thus resulting in the distorted tx audio.

Anyone that gets the original parts from a vendor is extremely lucky. A voltage or current applied to one pair of the transistor’s terminals changes the current flowing through another pair of terminals. KV6OMay 26, And their buyer protection seems to be too good not to give them a try.

Mitsubishi Electric Corp. 2SC Datasheet.

Bipolar transistors are so named because their operation involves both electrons and holes. You must log in or sign up to reply here. The first batch worked fine. I contacted Eleflow, I sent them pictures as requested and still waiting to hear from them ages ago, I Emailed several times!

Region Macedonia Kosovo Global. Bias set up according to specs with vatasheet issues. He explained how difficult is to find genuine transistors these days.

I even increased the bias setting to see if there was any change. Thanks for all the suggestions. Telecommunication measuring equipment Cable and pipe tracing Cooper networks IT networks Optical networks Spectrum analysers more Equipment for testing of medical equipment.

Computer components Hardware Network Notebook-Battery.

Until I get this sorted I will never order from Eleflow again nor would I recommend them to anyone. All were within data sheet spec, but the s I received are all coming up low at around 2. They measured the hfe of the 2SCs so they send a matched pair – I see they do the same with 2SCs. The only advice I can give is try the rigs manufacturer.

Fluke, Mikroelektronika, Knipex and Logitech. The ones I have would not even fit in a TS their body being slightly bigger. The first batch I had from Eleflow worked just fine but not last lot. Collector – Emitter Voltage Vceo. There are tell tale signs, Writing darasheet 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.

Hopefully at least ONE set will be genuine! They appear to look like genuine Mitsubishi devices, although the labeling differs ever so slightly.

That is just gotta be a logical answer Roger. They were shipped back and I never got a refund, they claimed never received. Same for a few other RF devices I measured.
