Also take a look at some pictures of the "inner" front panel and dial cord on my website at www.k9ew.net, under Projects, 525 PTO. You're right; the hardest part is getting started. Hope this helps.
The Allen wrenches are 0.050" and 0.060". I'll bet TenTec has them. 73, ed - k9ew On 10/21/06, JT Croteau <jt.w6fo@gmail.com> wrote: In my efforts to fix the dial indicator on my Argosy 525, I am hav
Hello Mats, If you're thinking of a CW Filter for the Argonaut 509, you might be interested in a Crystal Filter rather than an Audio Filter. I made an external crystal filter for my 509, and it works
Hi Doc, There's a small 4-pin accessory socket on the back apron of your 515. Without the 208A filter, you just insert a jumper plug that routes the audio back into the radio. With the 208A filter, r
Hello Mats, I just did a check on my 509, and I can adjust the RF Output power to all power levels you mention - by adjusting the Drive control. What you might need is a power meter that can measure
Don't forget that an attenuator will also be in the line for the Receive mode. A few db won't be noticeable, but 10db might be. 72/73, ed - k9ew Thank you indeed for all useful information. I should
Hi Giorgio, I have a couple of questions... 1) Have you called TenTec? They may be able to give you a very short list of things to check. 2) Does your PTO tune smoothly? 3) When you tune in a signal,
It's starting to sound like a mechanical problem with the PTO tuning as Jerry described earlier, and a rebuild may fix it. It's not expensive or difficult to do; it just takes some time. That's what
Just a detail... It would be better if you could run your RF into a dummy load so there'd be no radiation at all that could be getting back into the rig. If it were RF getting into the rig, you might
Hi Doc, This may be more than you're thinking of, but here's a thought... A few years ago, I decided that I wanted a single station speaker for the different rigs on my desk. At the time, there were
Backing off on the RF gain (not the IF gain) can minimize the excess signal power stored in the filter to make the thump. Unfortunately, there is no RF Gain control on the Argosy receivers. BUT... th
Hi Jerry, I think most frozen PTO's just need to be cleaned and re-lubricated rather than replacing parts. If you take a look at the N5FC website referenced in an earlier thread, you can do the clean

It's time to find a new home for many of the Boatanchors that I haven't used in quite a while and probably never will. Of course, I'll probably regret this once they're gone, but it seems like they d
The response was overwhelming... In less than 24hr, all boatanchors were spoken for. I will respond individually to everyone who emailed me, but I just wanted to say "Thanks" right now, and to let yo
Hi Russ, You will probably get several suggestions for relubricating your PTO, so I'll throw my two cents worth in the pile for you... First, I'd recommend rebuilding it, not just freeing up the hard
Hi Shawn, I was able to get the specified diodes, but had to go to two sources. One was Dan's Small Parts, and the other was Allied Electronics. There's some great information on PIN diodes on some o
I have an Argonaut V for sale (with fan and TCXO) that's in great shape, and has the latest upgrades (ver 1.08 SW, and mic audio). The fan has an ON/Off slide switch in case you don't want to listen
Hi Alan, I've use an external DSP filter with my Scout, and it does come in handy as you've described. I have an MFJ-784B, and I use it like an old Q-multiplier. It works great for any rig that doesn
