Ten tec triton iv modifications
This device has been installed and proven effective in a great many older rigs. From the K4DPK Web Page for the VFO Stabilizer circa 1/2011ĭPK VFO Stabilizer.Greatly reduces drift in conventional VFOs and PTOs. We discovered some other things we have in common, which made for Phil having a good understanding of the trials and tribulations I've been through in the past few years. It was such a pleasure and happenstance to run into Phil. Phil is also a fan of AM, and told me that in addition to rebuilding some Hallicrafter receivers, he's building up a kilowatt rig for AM. It turns out Phil's hamshack is predominantly Ten Tec! He's got nearly every major beast of Ten Tec's represented there. I gave Phil a call on the land line, and had a great chat with him. Phil is still making this device, which will be of interest to anyone with a vintage VFO on their hands. Apparently these have been made for many years, and I've got one of the old ones. Rather than re-phrase what it's about, I've excerpted the information Phil had posted on the web. Some Googling rapidly revealed the PCB to be Phil, K4DPK's VFO stabilizer circuit. I removed the PCB and found the callsign K4DPK on the foil side of the board (which hadn't been visible to the individual that sold me the rig).

There was a wire running into the main tuning capacitor chamber, and thought "wow, that's an interesting add-on".

When I received the rig - and fortunately the Ten Tec manual (not included with the radio, and not findable on the 'net), I found an extra board inside (as had been described in the eBay entry). Dial pointer hangs (gets stuck) at extreme left.Some noise on band select gang switches.Humm on AF filter option board (in CW1 and CW2 settings) - bad decoupler cap?.Added cork feet/shims/insulators to back power supply fin so fin doesn't touch the surface the Triton II is placed on.Test with 12a 12V switching power supply.Acquire manual from Ten Tec (couldn't find it on the net will post it here soon).Clean out dust inside, but note this unit was very clean as received.
