Re: C-4 Creativity
I’m pretty sure that they all came with one switched 240V duplex receptacle.? I have used mine for 35 years — I’ve owned it for far longer than the original owner, as I found some 1970 date codes inside it! I did try the rotor controller and it does work with Hy-Gain type rotators. I’ve never used the phone patch. The meter, power controller and antenna switch I have used always.? One neat thing with the unit is the rig control/select. There are three positions marked, but you can control (if I remember) up to 8 rigs but need to wire in anything beyond 3. I use it to switch my keyer and L7 amongst my B-Line, TR-4Cw, TR7 and Elecraft K3 (amp only). I could switch audio and mic but have fun having different mics on the Drakes. ?Still, the mics take up space, so I’ve considered having one mic socket somewhere on the desk and just picking a mic.? BTW, that antenna switch handles 1500W just fine! 73, Steve Wedge, W1ES/4 Time flies like an arrow.? Fruit flies like a banana.

Re: C-4 Creativity
开云体育Tom:Congratulations on getting the C-4.? It's a nice addition to the 4-line station.? I find that the stations accessories that Drake offered with the 4-line and the 7-line is a big part of what made these stations so special. Not sure if the 10 minute reminder to state your callsign is valid anymore - it never was up here in VE-land anyways.? At one time it was 30 minutes and at the beginning and end of a QSO. Phone patches are pretty useless these days, but I still use the clock on one of the C-4's and the wattmeter and the accessory switch to select speakers.? I have used the antenna switch too, though not at the moment.? That will happen again, possibly even this summer as there will be some major changes.? I also want to try hooking up a Hy-Gain rotator to that control, just for fun too, as have never done that.? I just acquired a free Hy-Gain Tailtwister control box with a blown meter so this is a good time to try that out!? I'll probably throw in a Brake Delay system which I am hoping will get around the issue of the absence of a brake release switch on the C-4.? Need to check that out further, though I think at least one individual on here said they were using the C-4 with a later Hy-Gain rotator without issue. And yes...I use the powerbar.? I have one C-4/powerbar controlling the power to the 5/7-line desk and one to a 4C and 4B line desk.? You can see these on my qrz page.? The 4-line desk is actually using a home made "powerbar-on-steroids" I made 15 years ago or so to control 220VAC to a Collins 30L-1/30S-1 and KWS-1, in addition to an L-4B.? There were plenty of extra outlets as well.? Making your own powerbar is not hard, requiring a good 220VAC contactor-style relay, a small 110VAC relay as the latch (if the contactor does not have a spare set of contacts), and a bunch of barrier strips, all built into a big Home Depot junction box.? I have pics and schematics if needed/interested.? One of the hardest parts to find is simply the 3 pin C-J connector that plugs into the back of the C-4! If you have the Drake powerbar, it is worth checking the wiring.? I found that one of mine had the neutrals and the hot leads backwards on the 110 VAC plugs! 73 Peter VE7PS On 2021-04-13 2:32 p.m., Tom wd8cqb

Re: C-4 Creativity
开云体育I too have a C-4. It’s without the power strip of course. I’m never going to use it so if someone is interested contact me at W5SUM at Comcast dot net.Ron W5SUM On Apr 13, 2021, at 4:32 PM, Tom wd8cqb <wd8cqb@...> wrote:

Re: R4A how effective?
AC9PA
开云体育?Hello Ten Tec had a NB board that was a optional on the Scout . Have seen it used in a R4C . Worked better than stock but not great.? ? Have also seen R4B with tx filters installed it worked but didn’t compare it to anything .Hihi? ? As far as audio filters used up at 50k hey you could play with it !? ?I type probably 100 words why not to but deleted it Hihi? ? If I had a R4B which had noise outside of house and I couldn’t fix the problem. I would and do use two antennas and change phase on them . ?MFJ and DX Engineering make a box for that . It works better than any NB I have ever used but it mainly only works on one noise ?that you tune out.? ?Don’t chop up the Drake Hihi just add some modern accessories!?

Re: 7-Pin Tube Base?
Just one but please don't go looking for them just yet.

I have an ancient VTVM (made by TIC - Technology Instrument Corporation) that used a 6AL5 for the HV rectifier. Due to the HV value, they designed it with both diodes in series (with balancing resistors across each); however, even at that, the ratings for each diode is very marginal - if not exceeding the ratings. I found that after a warmup, the HV was dropping from about 330V to 30V! I suspected the 6AL5 and substituted two 1N4007s. That worked and am thinking of using a tube base instead of wiring that under the panel. The designers eventually replaced the 6AL5 with a 6X4 and I may retrofit my unit with that but just haven't decided yet. I don't relish the idea of slamming HV to the amplifier tubes before they have a chance to warm up so not sure I want to go with the solid-state diodes. If I decide to go with the diodes, I may ask again but was just putting out feelers for now. Thanks so much for the reply. Thanks, Barry - N4BUQ ----- Original Message -----

Re: 7-Pin Tube Base?
BTW, the ones I had looked a little bit like the one shown about 1/3 of the way down this page:

Those only have a single hole to solder whereas the ones I used to have had a small ring on each pin at the top which made attaching components just a bit easier - especially if multiple components needed to be connected to a single pin. Thanks, Barry - N4BUQ ----- Original Message -----

7-Pin Tube Base?
Anyone know of a source for miniature 7-pin tube bases? I'm looking for the type that has a way to solder components to the top side and has the pins to insert into a 7-pin miniature socket. I think I used to have a few of them but I think I let them get away and now am not finding them very available, if at all.
Thanks, Barry - N4BUQ |

Re: r4b revival
Ron K0IDX
I'm thinking the problem is with T3/ switch contacts/ associated components.? The switch is clean but will check rotor contact.? Then I'm thinking of pulling v8, leaving d14 disconnected and with radio powered down look for resonance pin 5 to ground at the LO -? about 5mhz.? Does this seem a reasonable thing to do?? v8 showing no cathode current (v drop across resistor) says its not oscillating correct ?? ? Thanks for any thoughts on this. -ron

Re: DIN connectors
I'll add that a larger tip with more thermal mass will get the job done quicker.
