The radio workshop Welcome to my radio workshop! Here I repair and service our stations and accessories. My business is at a hobby level as I have a regular job during the day so repairs and service are only accepted to the extent of time and desire. I also choose the type of repairs I undertake depending on the availability of service manuals and spare parts and costs associated with the repair. Old cb-radios should preferably stay at the owners home when the ravages of time and screw-happy novices often put the radio in a condition that is not worth repairing. You are always welcome to contact by using the contact form at the bottom of the page. You can also contact me if you repair/modify on a slightly simpler level yourself and need support. In that case, write your phone number in the contact form and I will call you when the opportunity arises. An IC-7300 on the repair bench Tips from the coach. If you do not have full control and the right instrument park, never open the station to repair, mod or "tune" it. Never go into hidden service menu to "trim" it. Don't touch anything that works! Use well-tuned antennas, preferably antennas in resonance or close to resonance. All contacts and connections in the antenna system must be well connected and with good contact. Make sure you have no RF currents back to the shack. In case of high mismatch in the antenna system, use an external tuner instead of the radio's built-in one. For long transmit cycle digital modes, do not run at full power. Do not build the radio in such a way that the radio's fan cannot get rid of the hot air from the station. When connecting power amplifiers, modems, microphones or other non-original peripherals, ensure that all connections are correctly configured. If the radio is not working as it should, do a factory reset before you decide to send it in for repair.
