Hi JJ, I have attached a PDF of K7QO's TT13xx Assembly Notes. It is 334 pages long; should have everything you need. On ALL: You won't receive the attachment but JJ is BCC direct; he will receive it.
OK on all, Jon. Good luck with getting the radio up and running. 73, Rick, DJ0IP (Nr. Frankfurt, Germany) May the Sunspots be with us! Thank you very much, Richard AG5M and Rick DJ0IP! I bought this
Yes, Mike 'was' selling a kit to build a replica 245 filter. I bought on 2 years ago and still haven't put mine together. Mike, WB8VGE SunLight Energy Systems The Heathkit Shop http://www.theheathkit
Hi Shawn, That is the 9 MHz SSB filter out of a Galaxy/HyGain R-1530 receiver. The Argonaut's 4-pole SSB filter was not centered exactly on 9.000 MHz. I think it is about 9001.5 kHz. The same filter
Hey guys, on this great 1st Day of April, 2022, I am proud to announce: That I have developed a new line of 'Cutting Edge' antennas that well improve the signal of our 10-Tecs so much that they will
GM Mike, I sent you the 311 instructions and schematic in a direct email since we can't post attachments here. 73 - Rick, DJ0IP (Nr. Frankfurt, Germany) May the Sunspots be with Us! --Original Messag
The Argonaut 515 had solid state T/R switching; no reed relay. The reed relay was only used in the 505. 73 - Rick, DJ0IP (Nr. Frankfurt, Germany) May the Sunspots be with Us! Thought i would mention
A company in Bulgaria is building and selling a modern version of the Argosy. It is called the RGO-ONE. It is a single conversion transceiver using 2 Xtal filters; a 2.4 kHz first filter followed by
Well lets say mitigated the fault. The cause of the fault can be eliminated . . . if I remember correctly . . . by raising the pin to ground of a 7808 regulator and inserting a small choke between th
I'm progressing. Here is an excerpt from an email from June 2005. "They have found a noise emission in the LF-band, centered around 300kHz, at the Orion output, although at low level (he stated below
DANG, I'M GETTING OLD! I found an exact description of the fault and fix . . . ON MY OWN WEBSITE. I can't even remember when I published this; must have been many years ago. See: https://www.dj0ip.de
Hello Dave, This sounds like a dirty potentiometer for the drive control. It is a 25k potentiometer. If possible, try to clean it with a spray. It is definitely NOT the T/R relay because the 509 does
I have had to use the external cap a few times. In my case, 500 pF (additional) was enough. It is necessary when you have a very short antenna on 160m or even 80m. In that case you strap it in, but y
Before you dig into the radio, if you haven't already done so, place a good RF choke between the radio and the coax. You can try the WIREMANN Model 8231: https://thewireman.com/product/balun-11-curre
I had a small problem arise with my 7300 about 3 months after I received it. Its output of the band info (used for switching bands automatically on my linear amp) stopped working. ICOM swapped the wh

I don't know what the preferred cord is, but mine broke just hours before CQWW DX contest started. Found some elastic band in my XYL's sewing box, tried it; it worked. Left it in. 73 - Rick, DJ0IP (N
Vic, The OCFD is prone to Common Mode Current (CMC) problems. If you have it over a metal roof and especially so close, expect lots of CMC issues and you will possible lose a band or two. I don't hav
I have puled pins and pushed them back in many times. I used a very tiny screw driver. I pushed it in from the side where the two parts mate and bent the tiny latch in towards the middle. Then I pull
