How long does it need to be? I have a shaft from a Collins radio that is very strong fiber with flats most of the length and a 3/16 diameter by 1/2 inch knob shaft on on end/ You could use a piece of

Anybody got a nice MS-7 that they would like to sell?? If so please advise shipped price to 49534 Thanks, Eric K8CCA

Justin- Looking at the T4XB from the back, starting from the left you have a small knob that is the vox delay control, then immediately to the right of that is the key jack, which is a 1/4" phone

Rocco, Together they make a fine pair. I use my TR7A and R7A all the time. For the cable, try this link: http://www.dl7maj.de/TR7-R7-cable.pdf This is covered in the manual but is easier to read on

You will need a keyer and it will need to have a grid block output that you just plug into the key jack. I have an MFJ-422E that I use. 73 de Mike, W1NR

hi Tom, what jack specifically do you use to connect the key, or keyer to on the back? I’m totally blind, so I may need some sihted assistance in order to figure that one out. Thanks, Justin-ai5os.

Justin- You will need an electronic keyer capable of keying the voltages associated with older tube rigs. I use an old Logikey, it has provision for keying modern solid state TX as well as old tube

FOlks, I’ve got a Drake B-line station, the TX4, and the R4b, I‘m assuming there is not a built-in keyer for the thing, so if I were to connect a set of paddles, what are the appropriate jacks

*** Looks like I *might* have fixed it. I popped the bottom shield off to look at signals on the parent board. Hmm... it works better with the bottom off. How could that be? Looking carefully at the

I have an MN-2700 that the Resistive knob broke off at the knob. So my obvious question is: NOW what??? hihi! I searched the archive and didn't find any info on how I might repair. On the tuner the

Hello All! So - yesterday I did a mostly complete alignment of my Ebay "INOP" TR7. To measure frequencies, I used an HP 5385A counter. I verified that it was accurate with a GPSDO ( GPS Disciplined

Yes you need interconnect cables, audio, rf and control. See the pictorial vies in your manual. K0GNW

Yes, the R7 can connect to the TR7. The instructions for that connection are in the R7 manual, This allows the R7 to use the same antenna connected to the TR7. Nice combo. Been using mine like that

Hi Everyone, I have a Drake TR7 station that I use from time to time. It's a great rig and I love it. I recently picked up an R7 and I was wondering if there is a way to use it with the TR7. I don't

Lyndon all the magic happens in the remote box. IT’s a shame, too, as when one becomes a silent key, the widow just wants that ugly tower taken down, and with it goes the remote switch that was

Hi to the group. For output power, 2/3rds times input power (67%) will be very close for tube final. And about 1/3 on an avg type meter saying a long "Five" in SSB. The O'scope is very good for PEP.

If anyone belongs to the Collins Collectors Assoc. their latest issue features an article on measuring RF power and how inaccurate it can be even with the best of equipment. Measuring power if you

You really need a monitor oscilloscope on your transmitter. I have an old Heathkit. You probably do have enough gain as Richard says, but you don't see it on regular meters (plate meter and

Something is wrong.? These rigsvwere intended to work from either dynamic or crystal mics or the sort designed for high impedance inputs like public address amplifiers.? The D-104 without amplifier

I saw several places with Drake stuff, TR-3, several 2-B, TR-6, Twins, tuners & more. I attached a pic with what I came home with. Dave KC3AM
