That's great, Carlos. Hope you really enjoy your Argo6! 73, Rick, DJ0IP (Nr. Frankfurt, Germany) Hi Rick, Success. I have been away for almost the entire week due to work commitments (I'm very fortun
It's not normal for the Eagle to do that. What firmware revision are you running on the Eagle? 73 Rick, DJ0IP (currently on-site @ WRTC-2018) Folks, I ran my Eagle for about 16 hours straight in the
I recommend upgrading to 2.003. 73, Rick, DJ0IP (Nr. Frankfurt, Germany) Rick, I didn't think so either. Firmware is 2.001. It has the AT and the 300 Hz filter. 73 Mike It's not normal for the Eagle
Roger that! Especially if you mainly work CW. The 2.003 helps more on SSB. If you have an old computer running XP, the update is a cake-walk. Win-7 works pretty good, but a lot of people had difficul
Well don't expect too much from a single conversion 9 MHz radio these days. 14 or 15 people might buy one but the other 5000 hams want an SDR radio. Good Xtal filters cost $100 each and you need at l
GM Ron, The problem is, if you don't cater to the vast majority of "everyone" - i.e., the guys wanting SDR in this case, you won't be in business 5 years from now. The company I work(ed) for has been
I concur fully with Bob. In my opinion, these are the most versatile tuners ever built. Forget Johnson Viking, Palstar, and all the rest. The ARRL Labs has tested a slew of tuners in the past 20 year
LIKE 73, Rick, DJ0IP (Nr. Frankfurt, Germany) Oh....on a side note, My Omni VI Plus, with an SDRPlay does almost all of the same stuff, covers much more frequency, allows 4 or 5 different software fl
Long forgotten, and today I stumbled upon my old notes and even a choke for fixing the problem. I have uploaded this MOD to my web site: http://www.dj0ip.de/ten-tec-stuff/orion-acom-fix/ I couldn't f
Roger Carl; actually I thought it might have been you. I just couldn't remember. See you in about 4 weeks. 73, Rick, DJ0IP (Nr. Frankfurt, Germany) Hi Rick, That was me. But I no longer have the Acom
Do you not have a schematic, Shawn? If not, you can download it here: www.dj0ip.de/ten-tec-stuff/omni-a-d-manual/ It's not very difficult to determine which transistors are the finals. They're pasted
GM Scott, I believe your tuner must be a 238, not a 238A. The "A", the dial and dial cord was replaced by a turns counter, and it is identical to the 238-B, except for the color of the enclosure. In
Speaking of restringing, mine once died just a few hours into CQWW DX contest. I found some elastic band in my XYL sewing box. Not sure what she uses it for but it worked FB in my 238. 73, Rick, DJ0I
In mint shape, the going price is about $300. However in the meantime, many are not exactly in mint shape anymore. 73, Rick, DJ0IP (Nr. Frankfurt, Germany) Ouch! I think I saw a 238 sell on eHam in A
That Cap issue is only a problem with high power. I have never run more than 750w with mine and usually only about 500w. I did purchase the caps (in Russia/ebay) but never bothered to install them be
Malcolm, Here in GERMANY we use a cleaner called "Kontakt WL". It is actually just a rinse. For really gummed up Contacts, we apply "Kontakt 60" (cleanser) and let it sit for about 15 minutes. The we
Hi Guys and Gals, I took advantage of the Easter Holiday to do some work on my web site. Here are a few pages that might interest you: * New RF Choke Design: Maxwell House RF Choke <http://www.dj0ip.
Good question, Bob, I did the cutting edge antennas more than a year ago, over a period of a few months. The Maxwell House Choke idea came to me as I was recently describing the Maxwell vs. Guanella
Bill, I have lots of Ten-Tec manuals and schematics but I don't have the KR-645. If you get anything on it, please forward to me. Tnx. 73, Rick, DJ0IP (Nr. Frankfurt, Germany) Need a schematic and bo
