Anyway, I installed a pair into the TS I even increased the bias setting to see if there was any change.
Add to cart On stock. The only advice I can give is try the rigs manufacturer. Hopefully at least ONE set will be genuine! The last thing I can come up with is Eleflow.
All were within data sheet spec, but the s I received are all coming up low at around 2.

Fortunately my payments were quickly and fully refunded in both cases. Same for a few other RF devices I measured.
Education equipment Industrial test tools Catalogues Laboratory measuring equipment Measuring of environmental and ambient parameters Equipment for testing of medical equipment Calibration equipment Soldering equipment Telecommunication measuring equipment.
Just like Cliff I used Eleflow before and without problems.
Equipment for testing of medical equipment. G3YROMay 26, I am guessing that he may not even be aware himself that this time around there is an issues with his supplier. I contacted Eleflow, I sent them pictures as requested and still waiting to hear from them ages ago, I Emailed several times!

A transistor is a semiconductor device used datasheet amplify and switch electronic signals and electrical power. The customer is in the focus We want to make sure that customer is the center of attention. I purchased 2SCs from this same broker a few years back with good results, so I did not hesitate to try him again. A small current entering the base is amplified to produce a large collector and emitter current. Until I get this sorted I will never order from Eleflow again nor would I recommend them to anyone.
However, on SSB I am hearing distortion on my transmitted signals. They list the transistor as being in their current production list.

My experience with Eleflow. Calibration equipment Electrical calibration daasheet Pressure calibration equipment Temperature calibration equipment. Well, two separate suppliers from AliExpress, and both were counterfeit. 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. The radio makes full power on all bands, and the power control is right on the money from w.
That is just gotta be a logical answer Roger. G4COEApr 27, Next, I decided to perform an HFE gain test on the devices received.
Collector – Emitter Voltage Vceo. They may have unusually high hfe. I suspect the low HFE may be causing poor linearity or poor slow RF switching, thus resulting in the distorted tx audio. Lettering easily smudged as if wet.
