Recently added to my shack. Hallicrafters SX-100 which I currently have paired up with a Drake TR-4 as the transmitter. Searching for a suitable transmitter. I purchased a Ranger which needs some TLC, a good friend of mine will take a look at it and see if it can be revived. So for now the TR-4 does the trick. I use it on the RCVE mode, it transmits and mutes the SX-100 and supplies the antenna feed to the SX-100.
