I finally got a genuine 2sc1266 driver for the Emperor..replaced the 330ohm and the 47ohm that is parrelel with the driver choke.. the 477 is not soldered on yet.. I removed the bias bridge, adjusted the driver bias pot to 50mA, and it stays steady..put back the bridge. At SSB mode no...

Nomad, heres what I have..

Hi guys! the 2510 ssb is working great, was overgained..thks.. Now got this problem..no PTT from a Easy Digi board..serial usb cable is fine, sends 5 volts to the board everyday..but the PTT is not working..I see 2.3k ohms between PTT and PTT ground when I press Test PTT..the mic TX pin shows 6...

Hi! long time no see lol.. got a nice 2510 pretty cheap..monitoring on another radio,AM tx sounds perfect...but SSB is like clipping real bad and my dmm at current mode is showing crazy draws at SSB with a 1khz signal.. MRF 477 is going, right?

I have 2 TRC-449 that had the same issue..very weak RX..you can stick whatever you got osci, generator, whatever and its a bitch to trace back.. These had that typical scratchy RX that triggers me its a filter problem.. And that was it was! C10, a ceramic cap besides T3, was split open..This cap...

its made with soft steel brake line, and the radial are soft metal from the beach chair..each leg is 2.5 long and 8 turns of insulated copper wire, the rest is left hanging.. its 1.2 from Ch. 1 to 27.495

This radio was found at a garage sale..Channel display was flickering, some Deoxit fixed that..otherwise this radio is walking legal at 4/12 watts and it seems it was never tinkered..but compared to my Teaberry Ranger T and the TS-450, its quite soft at receive..Public Address output is very...

I got this radio for a trade.. TX and RX are ok.. But it has a weird problem. the display overbrightens, lighting a bit segments that are not in use..its like the backlight is too strong.. is this like that or is there a way to correct this?

on my bench..the mosfets are replaced and upto now its TX per specs..But I was itching to measure voltage but didnt dare to..usually these radios are calibrated by measuring current draw at the DC..anybody would happen to know voltages on the fets?

Finally did this one! was a trade for tiny mobile cb.. This bad boy was a wreck..blown power supply, blown final, RX upto ch 32.. Fixed all that, replaced the 4 amp PS trans for a 10 amp rate and a new final.. 5.5 deadkey swinging upto 19 pep.. The handset needs a new cable, it causing feedback...

The Emperors are on hold until I get new drivers and finals.. Im working with a TRC451 which was given to me and it was really messed up..so far I have fixed the RX section pretty much accurate possible with no osc, just a sdr and a TinySa as a signal generator.. this radio has a missing choke...

Hi.. I installed only the driver 2166 which is new, and tested current on the test points..it goes from 0.30 to 1.3 and I stopped there, was getting to hot...all trimpots are adjusted accordingly by the service manual..any suggestions?

Good afternoon..Ive been using a chinese sdr radio with a short AV line and a 101k cap..it this safe or what would you recommend me? its sniffs TX signals ok but doesnt pickup IF like a 17mhz RX crystal signal at test points..I also have a TinySa but I only use it as a signal generator, becuase...

Im currently testing a 5010..it doesnt barely TX so I removed final and driver..I measured voltage at the driver base and its not stable, jumps around from 0 to 8v..traced backed to the predriver, removed it and same thing at the base pad..I furthered down to the 2 transistors right before the 3...

Hi all.. Due to the lack of MRF477, Im reading that the 1945 is a drop in substitute.. Is there anything to adjust on a hr2600? thks!

Hello.. I recently got a Teaberry Ranger T..this radio had its final and driver missing and I installed the pair from a TRC451.. This radio is a charm receiving..it pickups signals where my SDR928 doesnt! My problem is theres a low crackle and pop sound on CB and PA mode..I replaced several caps...

Looking if anybody can share a copy..Sams credit card system doesnt recognize my bank card..Sear Roadtalker 40 SSB , the old one , which has a 40 marked center knob no LED display..
