The old Hallicrafters TO keyer with its mercury wetted relay will key anything, even high current together with high standoff voltage if you install the right RC snubber. The Nye Viking ESK-001 is kind of hard to find but it features both neg and pos (switchable from the rear panel) 300V transistor switches, making it one of the few transistor keyers that can easily handle both cathode keying and grid-block (like the Drakes). I have both a TO and the ESK-001. Be careful of the modern IC keyers on the market. Many of them do not handle neg keying and their max voltage is typically under 50V. You could always build a HV interface circuit if you wished. I did and use it with my low voltage keyers.

Re: [drakelist] An Introduction a question about keyer for T-4XB
Garey Barrell [EMAIL PROTECTED] made an utterance to the drakelist gang -- Steve - The DX-20, like many of the small transmitters of its type, is cathode keyed. What this means is that while the voltage across a key is positive related to ground, the open key voltage can be several hundred volts, and the full cathode current of the oscillator and final have to pass through the keying device. Definitely a place where a KEYSALL or similar is going to be required for most modern keyers. The HA-1 will handle it, with the appropriate snubber network. The Idiom Press keyers will not SAFELY key this transmitter without an interface. 73, Garey - K4OAH Glen Allen, VA Drake 2-B, 4-B C-Line Service Supplement CDs www.k4oah.com Steve Berg wrote: Steve Berg [EMAIL PROTECTED] made an utterance to the drakelist gang -- I appreciate the information this thread has produced.

Re: [drakelist] Drake Nets
Good afternoon. I'm new to the list. I've had a T4XB and an R4B sitting on my workshop shelf for way too long and have decided to bring it back to life. Don't have a lot of experience with Drake, but do have 40 plus years in the hobby and an electronics background, though I haven't done a lot of electronics work recently. So - I'm starting with the T4XB. It works, but power output is low. Here's what I get (into dummy load, tuned for max power out, per manual): Po = 70 W Ip = 200 mA Vp = 690 V Bias = -55 V (70mA resting current) Looks to me like I need new finals. Am I missing anything? Want to be certain. Also, can someone recommend a reliable source for 6JB6's? Thanks 73, Wayne N1WR Lusby, MD

RE: [drakelist] An Introduction a question about keyer for T-4XB
Duane Calvin [EMAIL PROTECTED] made an utterance to the drakelist gang -- Frankly, for some things, like calling CQ if you don't do it with an programmed keyer, iambic is much more efficient. Squeezing off an A for example is easier for me than hitting thumb then index, even though they seem like very similar motions. C's and Q's are much easier. I don't use iambic very often, but I practiced the CQ sequence because I do it manually when mobile, and it makes calling much easier. Most of the rest of the time, because I learned on a bug, I tend to slap the paddle more as if it were a single lever. I've found dual paddle keys to be better built, more available, and easier to use than the few single paddle ones that are available, and they work as well with either mode.

Re: [drakelist] L7 Capacitors Needed
Dennis Monticelli [EMAIL PROTECTED] made an utterance to the drakelist gang -- Another option is to use a transmitting ceramic capacitor of the doorknob variety. The smaller ones are typically rated at 5KV and built to handle much higher current ripple than a typical bypass cap. Their RF qualities are excellent. I mention this because these small doorknob caps are often found in junk boxes and at hamfests selling for very reasonable prices. There may be somebody on the net with something in the 500 to 1000pF range or if you ask some friends a unit may turn up. If I were you I would replace both bypass caps with a single transmitting cap in the 1000 to 5000pF range...basically whichever value you find. A single doorknob will probably outperform two paralleled discs. I noted in my L7 schematic that Drake also used two in parallel to do plate blocking from the PA tubes to the output network. Clearly, Drake was shaving nickels buy using a single part type multiple times to lower purchasing costs. Two HV discs cost a lot less than a single small doorknob anyway.

Re: [drakelist] An Introduction a question about keyer for T-4XB
Dennis Monticelli [EMAIL PROTECTED] made an utterance to the drakelist gang -- Hi Steve, I dug out my schematic and it actually takes a few components. My recollection was only of the inductor. Basically you place a series LC circuit in the secondary of T2 to filter out the harmonics from the sawtooth before they reach the speaker. I first elected to lower the freq of the sidetone down to 750Hz because that was more to my preference. I simply placed 160pF across C8 to accomplish this. The series LC filter is then made resonant at 750Hz. I used a 31mH torriod in series with 1.33uF of capacitance (formed by a 1uF in parallel with 0.33uF). Other LC combinations of 750Hz resonance will work as long as you are mindful of the series R of the inductor, which determines the Q. If the inductor is too lossy, the tone won't be as pure. Correspondinly if the Q is quite high then then you may have to tweak either the oscillator or resonator capacitor to match up the resonance to the oscillator. I have probably made it sound harder than it really is. The mod worked first time for me using an inductor out of my junk box. I think the Q fell between 5 and 10.

I have a Tick keyer that just uses a single CMOS PIC controller and I find I can use it just fine pretending it is non-iambic. I agree with you regarding the memoryless TO keyer. It is unforgiving. On the plus side it will teach you to send better code :-) It comes out of the closet at my QTH only during the vintage contests. I did do a simple mod to turn the raspy sidetone into a nice sine wave. It only took one additional component.

I had to drag out the manual and check it out. I used to be able to send good code with my W9TO keyer but bought a new Nye keyer in the mid-1980s along with a Bencher Iambic key. I never learned how to use iambic mode and don't care about it. However, I did become accustomed to the dot and dash memory and now I can hardly send without it -- especially below 25 wpm or so.. So, the TO keyer is not getting much use anymore. (But it looks *so* good with the Drake 4-Line!) The Nye and the CMOS-4 both have dot / dash memory and the memory function works even with a non-iambic key. With an iambic key connected to the CMOS-4, I don't find *any* mode that is not iambic capable. What V mode are you using? Are you running V9 with no dot/dash memory? And, more generally, what is the difference between Curtis, Accukeyer and Logikey modes? I've tried the various modes now and other than dot and dash memory options I don't see much difference. Man, I've been pounding brass since '65 and I've got a lot to learn! 73, -Doug, W7KF -- Submissions:[EMAIL PROTECTED] Unsubscribe:[EMAIL PROTECTED] - unsubscribe drakelist in body Hopelessly Lost:[EMAIL PROTECTED] - help in body of message Zerobeat Web Page: www.zerobeat.net - sponsored by www.tlchost.net -- -- Submissions:[EMAIL PROTECTED] Unsubscribe:[EMAIL PROTECTED] - unsubscribe drakelist in body Hopelessly Lost:[EMAIL PROTECTED] - help in body of message Zerobeat Web Page: www.zerobeat.net - sponsored by www.tlchost.net -- -- Submissions:[EMAIL PROTECTED] Unsubscribe:[EMAIL PROTECTED] - unsubscribe drakelist in body Hopelessly Lost:[EMAIL PROTECTED] - help in body of message Zerobeat Web Page: www.zerobeat.net - sponsored by www.tlchost.net --
