Quick repair today as I got back home late Friday and heading out early Monday so no time really but just needed a dab of solder on the antenna so239 connector and a new Rx amplifier transistor. This seems to be one of the original mrf455 DX250’s that folks love. Beyond those small fixes, has spec output and clean modulation.
Have quite a few hams here in Vegas and close by that are always interested in these because they only need a 20-30 amp supply, smaller foot print and these days , work excellent on those SDR low RF output transceivers like the Xiegu 90.
If anyone needs Texas Star parts besides the RF transistors, let me know as I have most caps, resistors and relays. The ones that have bad RF finals, typically there’s more wrong and one needs to start testing all passive components for OEM specs, my opinion of course. Use of high quality and tight on tolerance of parts, these TS will last a long while for you.
