Just put the 2m LPF unit into a nice Eddystone Diecast box. used RG-402/U for the Input and Output connections to N-Sockets. This also includes a Harmonic Filter that allows all Harmonics to a 50R Load instead of them being seen as High Return Losses by the Amp.

The fully populated QSK boards from W7RY, Bare boards from Jim in the US, and all parts bought from UK. These will add QSK capability to the TL-922's an Improved Bias supply via a TIP147 and a Supply to allow the use of LED's to replace the Bulbs for indicators and Meter Light's. Also the Bias is fully adjustable to so Bias can be set on Valves for the Correct value for the Valves in the amp. Handy when going from Old to New Valves.

Yaesu FT-840 brought in with a problem of radio would flash on the display and it would lose all RX and TX and Audio. A test of the DC supply rails showed the problem 5v DC Rail was low with 4.5v DC showing on Output, Cause Low Input voltage from 13.8v Rail showing only 6v!. Replaced Resistor that is shown that someone had put in. Should have been a 8.2OHM NOT the 22OHM they used!!!! One replaced it sorted ALL the problems out with rig. Gave the rig a thorough cleaning, removed all k***s and front panel and washed them to get rid of grime so I could test radio correctly as quite a few of the buttons wouldn't work when pressed. Owner thought it was a different rig after the Clean and polish.

Icom IC 251E 2m MultiMode dropped off to the Workshop with a problem Power ON/OFF Switch. Corrected that problem and then onto the test bench for a quick check, Good TX power AND as can be seen a nice RX result too which is down to the fact the radio has a MuTek Frontend fitted. Good Little rig to say how old she is. Owner well happy and ready to use now on UKAC nights on 2m SSB.

Kenwood TS-850SAT in for test and repair. Found Dry Joints on the CAR board so reworked all the PCB with Hot Air Rework Station and there was also a Pair of faulty Driver Transistors, which was replaced with a nice new set of 2SC3133 that I had left in stock. Radio now back with owner and full 100w output and a very happy chappy.
