Re: [Drakelist] Sherwood mods
What an interesting selection of replies, I am not into drilling holes in equipment at all, so all the mods will be reversable, some are just common sense like changing out caps and the power board, however I do keep all the 'bits' just in case I wish to sell the radio, but this one is a keeper. I have had a great deal of focusing on my collection recently and am only keeping a select few items that I enjoy using, some are Collins some are Drakes, my BC-610E, the rest are various collectables which are used for short time only, however this R4C is a nice radio to use but it does have some issues all of which have been addressed here in some view or another, I actually fall into both camps of keep original and make sensible mods, I did the AGC mod to my early KWM-2 and it transformed the radio into a very useable and fun radio to use, the R4C is a great radio and there are quite a few of them still in service, testiment to the great engineering of the day so I do not feel so guilty for doing some small changes, but I wanted to get a flavour of what can be expected and everyone here has given their opinion on what is good and bad, actually not so much bad as good I feel. Anyway great group and many excellent replies, Thank you, 73 & HNY, Max M0GHQ___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist
[Drakelist] R4C Sherwood mods
I am thinking about doing the full works Sherwood mods on my R4-C. Which are the best to do?

[Drakelist] AGC on R4B
My R4B which I was refurbing for this W/E CQWW has a couple of issues, firstly the power supply intermittently hums, I can see that the Cap is loose on the power supply board and the resistor has been badly replaced so is probably the problem there, is there an upgrade board available as this one has lost some tracking, the other is the AGC in fast and slow there appears to be a certain amount of distortion and cracking on speech peaks, is this normal or do I have a problem here, don't want to investigate this if is a normal occurance. thanks in anticipation, Max -- I am using the free version of SPAMfighter.

[drakelist] Low output from L-4B?
I have noticed recently that my L-4B only seems to be putting out 800 to 1000w to the antenna on SSB setting and around 600w on tune key down, is this correct or are the 3-500z's getting a bit old, I thought I was getting more than that sometime ago but cannot remember. 73 Max

Re: [drakelist] Grease for 4 Line PTO Ball bearing etc.
Bent, Do NOT use copper grease on any bearing surfaces like ball or roller bearings, it is designed as a heat transfer grease like for brake pads, screws and heatsinks, but not bearings, the small particles will interefere with the smooth surfaces, light Lithium based or or any of the light high temperature greases are fine. 73 Max M0GHQ - Original Message - From: Bent To: [EMAIL PROTECTED] Sent: Saturday, January 26, 2008 8:31 PM Subject: [drakelist] Grease for 4 Line PTO Ball bearing etc. Hello All Is someone able to inform me which type of grease can be recommended for the PTO ball bearings, and between the shaft and brass bushing for the dials for the R-4C, T-4XC, TR-4C etc. Can I use a normal ball bearing grease for the car wheels etc. Esso Beacon EP2 grease.

[drakelist] L-4B fan
On my L-4B the fan switches off when the power is disconnected (normal), has anyone made a system using the original components to keep the fan running for a few minutes after switch off? I did this with my other linears and it does extend the tube life, trouble is with the L-4B it has a 110v fan that operates through the filament transformer to reduce the 220v to 115v. in order to make it run on you have to have the filaments on which defeats the object a bit and doesn't the psu get hot after a 4 hour contest, I know where I can put my 'Chinese takeaway' next time hihi.

[drakelist] C-line
I have been looking very carefully at buying a C-line, there are a few questions I would like to ask, 1, Are there any major faults to look for, I expect rigs of this age to have some faults, however are there any particular things to look for. 2, I notice they produce AM, now I am assuming this is not pure carrier AM but re-inserted carrier. 3, I have a Collins transceiver and it is sadly not too hot on the CW transmit side of things, (design, not faulty) are the C-line transmitter good for CW. 4, What sort of price to expect to pay for a good condition C-line? Thanks in advance, 73 Max

Re: [drakelist] manual schematic for L-4B
Evan, Found it and printed a copy for my notes, thank you, I could not get the mods.dk to give me a password or anything so gave up on them for the moment. I'll try them again someday. Meanwhile the board and components are from Ramsey electronics and it is an RFS-1, some sort of remote RF switching, could have switched by accident or not and caused the burnout. I can strip it out now, don't want any 3 legged fuses causing problems. 73 Max

Re: [drakelist] Drake Radios Keep You Warm
"AirRadio" <[EMAIL PROTECTED]> made an utterance to the drakelist gang -- Kevin, Snow is a funny white stuff that comes from the sky during the winter cold months, When my wife (Filipino) first came to this country, UK, she had never seen snow in her life, during her first winter here it snowed a lot, I took her to the local shopping centre, during our walk around the centre I became aware there was water trailing along behind here. I casually asked why she was 'leaking' and discovered she had collected both coat pockets full of snow as she wanted to take it back home and keep it. She also asked what they were going to do with all the dead trees around as all the leaves had fallen off ! Thankfully I also have all my tube/valve radios here in the shack to keep me warm during the winter months, not a 3 legged fuse in sight. ahh that warm winter glow, 73 Max M0GHQ -- 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 --
Re: [drakelist] L-4B on AM
"AirRadio" <[EMAIL PROTECTED]> made an utterance to the drakelist gang -- Jim, Thanks for the note, Yes I fully understand the carrier input etc, what I meant to say and put it badly was by how much was 100w too much, I did guess that 25-30w input was probably about right. maybe much less. I have a Collins ART-13 which I use regularly on AM nets and wondered how much I would have to attenuate it to run a sensible output with the Drake. Maybe it is not worth it but possibly if the Drake puts out a significant carrier, I was aiming for roughly 300w carrier maybe that is pushing the L-4b too hard, regards Max - Original Message - From: "Jim Shorney" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Sunday, December 16, 2007 7:51 PM Subject: Re: [drakelist] L-4B on AM "Jim Shorney" <[EMAIL PROTECTED]> made an utterance to the drakelist gang -- On Sun, 16 Dec 2007 18:18:29 -, AirRadio wrote: Hi gang, Has or does anyone run an L-4B on AM, if so what is the max output to the antenna expected with 100w carrier input, having said that is 100w too much for the input, regards Max Yes, 100 watts is too much. You need to understand the PEP-to-carrier ratio involved with AM. The manual states that with 100% modulated AM (I assume this to mean full-carrier, both sidebands), the transmitter should be adjusted to produce 500 watts DC plate input in the amplifier. This translates to 250-300 watts carrier output. If you are using a Drake controlled-carrier AM transmitter, adjust everything per manual specs and you should be OK, but in any case do not exceed the maximum PEP ratings of the amplifier or the maximum legal limit allowed by your licence, whichever is lower. I'm sure one of the gurus who lurk here will come up with a more complete answer... 73 -Jim -- Ham Radio NU0C TR7/RV7, TR6/RV6, T4XC/R4C, L4B, NCL2000, SB104A, R390A, GT550A/RV550A, HyGain 3750, IBM PS/2 - all vintage, all the time!
