Did not get on the air today, as I spent most of the time adding additional metering to the 139XLR to better understand what's going on in its circuitry. And, I removed two earlier mods that have shown to be overkill. Then I added a ferrite toroid choke to the antenna input of my Quad6PRO in...

Turned on the Q6 PRO. Heard Dr. Dx out of Tx. Shouted out to him and his reply was covered up by noise. Then heard 7787 out of Washington state calling for me. Hooked up for a nice two minute QSO. Propagation was strong enough for him to get over the Q6's noise. Notice that I was using Receive...

I was in the shop working on my 139XLR, and monitoring 37LSB on my quad 6 pro. I could hear stations in there, but they were covered up by the 3-5 S-units of noise that this rig generates. Turned to 39LSB , and recorded a few seconds, note that I had the Receive DNR, NB, and the Hi-Cut all on...

Hey K9FON - A question about the "no receive" problem. Is there no receive in both AM and SSB ?? You said you have receive with loud stations. I would check the receive protection diodes (D64/65) . These are on the solder side of the board and were added as a fix post-production. 1N914...

Just viewed the propagation this morning. Showing lots of DX into the southern parts of South America: Argentina, Paraguay, Uraguay, Chile, and Brazil. Mostly Iono-scatter and Trans-Equatorial Propagation. Nada into Colombia. I am going to get online around 10 AM and try and change that. Let's...

HEY K9FON - You ask a generic question, you get a generic answer. You want specific things to check, but you don't provide us with any specific things you've done to diagnose the problem. "No receive" covers a wide spectrum of possible problems. Chris (Nomad) posted a reply that he thought...

Had that happen too. Always have the wife film whenever I open something. A picture is worth a 1000 . . . J.J. 399

I was aware for the need for some attenuation. So I added a 4.7Kohm 5W resistor in series with the hot side of the Q6's Ext spkr out. Didn't want to blow my Koss or Audo-technica Phones. Same attenuation scheme used on some variations of the 858SSb chassis (not the 139XLR though). Reduces the...

All of my other rigs have Zero noise floor. Kenwood TS430S, Cobra 139XLR, Cobra 148GTL-Dx, SBE Console IV. No noise with no signal even at full volume. Quad6 shows 3-4S units and has lots of static and popping noises, even with DNR. I ran it on a car battery just to make certain it wasn't supply...

I totally dislike the receive on my AT6666PRO !!

Gonna hit the airwaves (37LSB) about 4:30 or so this afternoon. Let's hook up.. J.J. 399

Tried the Koss headphones off of my desktop. Worked fine. Awaiting the 'phones I ordered from Amazon. 73. - J.J. 399

My thought too. Made a stereo to mono adapter. Radio didn't like it. two 8-ohms in parallel over-loaded the audio chip. J.J. 399

looks like what I need. Did an Amazon search. Didn't see those. Gracias Amigo. - J.J.

I want to buy a set of MONAURAL 8-Ohm headphones to use on my AT6666PRO. Needs to have a 1/8" (3.5mm) plug. Stereo phones won't work. I have a set. Looked at DX Engineering, and others, but no mono phones. Suggestions ?? J.J. 399

I bought the 900 PRO for my wife Luz's mobile. I had an old Superstar 360 fm in it, but it looked dorky. Too big !! The 900PRO is a better fit. Took the 360fm and put it on her base in place of the Superscope 640 she was running. Worked out perfect when she couldn't get home because of the...

Me neither

Is there a site that monitors 37LSB and streams it live ?? I've never heard my station and want to know how I sound J.J. 399

FB - Glad you had a successful procedure . Heal fast. Hope to catch you on the air. 37 LSB after noon today. 73. - J J. 399

I got on Channel 37L about 2:30 in the afternoon and heard nothing but static. Called CQ-Dx and was surprised when 7250 Lake Havasu AZ came booming back. Amazing because he wasn't even moving the needle off the peg. . We finished up and RG101 , Jack in the Shack, on the big Island Hawaii gave me...
