[Drakelist] What have I done now?

Hi all, Still waiting for better weather to put up an antenna but then ready to go with my TR4/AC4 which are fine into a dummy load, or at least they were! Bought a, supposedly good, AC4 as a spare. Decided to power it up gradually with the TR4 as a load. Two hours at 50v, two at 80v, two

[Drakelist] MN-2700/B-1000 use

I have just been fortunate enough to obtain an MN-2700 with Balun. Sorry if this is slightly off topic, and I hope it is not a silly question, but if I feed an antenna 150 foot away with 450 ohm twin feed, will it matter if it passes through two mature pine trees whilst on its way? Also, if I

[Drakelist] All is well

Hi all, How time flies. Been tied up with family matters for the last few weeks so not had chance to install the new crystal for 15 metres until today. Delighted to say that the TR4 is now working just fine on all bands, into a dummy load anyway. I was wrong in thinking the problem was

Re: [Drakelist] New R4C owner

Alan, you could have taken the words out of my mouth. I have been pondering exactly the same question with regard to the RX side of a recently acquired TR4. Anyway, you can be sure of getting an amazing amount of help from the guys on this net and I will look forward to hearing the advice you

[Drakelist] TR4 - Deoxit arrived

Deoxit (Red) is hard to find in the U.K. Had to buy a box with four types in it. Expensive too but I did not want to wait for mail from the U.S. I am sure they will all come in useful. Cleaned all crystal pins and sockets as advised. Instantly solved my, self induced, problem with

[Drakelist] Exploding caps - further progress

Steve, Thanks again for all your most useful input. I will certainly be contacting International Crystal. Your memory is only off by a fraction. It is the 20 metre band which is 'backwards'. Regrettably I do not have an oscilloscope but recognise that I am going to need one. My main

[Drakelist] Exploding caps - further progress

Steve, Thanks for your further input but, I do not think I have any accessory sockets! Being a quite early TR4 it has the whole of 10m with three crystals. I believe later models only came with part of 10m as standard. The only crystals I have not removed are for 28.5 to 29.1 and 29.1 to

[Drakelist] Thanks guys

Thanks a lot to all for the info. I have ordered some Deoxit D100 and will use as advised. In the meantime I will carefully check all the connectiions off the rotary switches as previously suggested by Steve. 73 DamienG3XER

Re: [Drakelist] Exploding cap? Further progress?!

Thanks Steve and Chris for your helpful advice regarding a possible bad crystal. I think you are right but somehow, despite being most careful, I seem to have made matters worse! Are 45 year old crystals particularly delicate? Should I renew them all? Tried the 15m crystal in

[Drakelist] Exploding cap? Progress

Hi all, It is time I gave all you kind folks a progress report. Found the WB4IQK AC3/4 troubleshooting guide invaluable. Tested all voltages with the covers off, very carefully! All okay. As promised by the seller I found that the two caps and four diodes in the 650v circuit have been

[Drakelist] Exploding Cap' ???

Hello all, I am embarrassed but most grateful for all the kindness and helpful advice given to me. Too many to thank individually but many many thanks to all. The safety advice is taken very seriously and I will be ultra cautious bearing in mind my inexperience. Already I am puzzled.

Re: [Drakelist] Exploding cap's ???

Wow, thank you so much to all for the most useful information. Yes the AC4 is wired for 240 v. Hoped to string up some sort of temporary antenna this weekend and get on the air but I now know I will be busy doing something else! Just hope I have the technical abilty to sort it

[Drakelist] Exploding cap' ???

Hi all, Bought an immaculate looking TR4 which has been out of use a long time. Also bought an AC4 which claims to have had the original EHT caps and diodes replaced. Powered them up with 20 vac for four hours, then up in 20 v steps at four hours per step, listening and sniffing for any

[Drakelist] Station upgrade

A most interesting thread. However may I ask for a clarification please? I have always understood, mainly from Bill Orr's wonderful but out of print books, that a 5/8 vertical had the lowest angle main lobe and hence was superior for DX to a 1/4 wave vertical, all othrer factors being equal.

[Drakelist] TR4 and TR4CW interface to Collins 30L-1

Hi everyone, I have a TR4 and a TR4CW and have just bought a Collins 30L-1 amp. I have no knowledge or experience of amps at all. Is there anyone who could kindly advise a 'dummy' of an easy way to interface the two? As I understand it the 30L-1 requires 170 volts to be switched!
