[drakelist] OK TR-4 Transmitter Next

OK.   Got the power supply and receiver going. Now I need to work out the Transmitter.   I am not getting any drive at all. I adjusted the bias. The relays are operating. However, I get about 1 to 3 watts out and that is it. There is almost no current at all.   There is also a loud pop in the

Re: [drakelist] R4B vs R4c

I have owned Drake A-line, B-line and C-line equipment.  I acquired a Heath SB-300 while I owned the B-line and was shocked to find the Drake's selectivity was noticeably inferior to the SB-300's selectivity.  This was due to Drake's use of an L/C network to achieve variably selectivity, whil

[drakelist] R4B vs R4c

I would like to hear from those of you who have used both. What are your opinions?   1) Electrical Performance Comparisons   2) Mechanical performance (PTO tuning etc.)   Thanks,   Jim N4BPM

RE: [drakelist] Knobs for C-line

Hi Nick and the list,   Many thanks for the numerous reactions. I am allready assured that my T4XC will be fixed thanks to some great friends here on the net!   Best 73, Dick/PA2DW -Oorspronkelijk bericht-Van: Nick Verbeek [mailto:[EMAIL PROTECTED]Verzonden: vrijdag 28 januari 2

Re: [drakelist] Re: [drake-radio-operators] Overvoltage powersupply

Have you measured the line voltage. I find in our area it is not uncommon to see about 122 VAC which can affect your PS voltages.   Alan KB7MBIWoodinville, WAMember ARRL / ARS / FISTS / NAQCC

[drakelist] Re: [drake-radio-operators] Overvoltage powersupply

Don't know if this will help you out, but I just measured the voltages coming out of my stock AC-4 power supply (NOT connected to the radio):   Hi Voltage: 698 volts Low Voltage: 268 volts Bias Voltage: -54 volts   Your power supply may be ok, but the voltages are a little high. Maybe someone more

Re: [drakelist] Knobs for C-line

Hi Dick,   I had that happen to the bandswitch of my T-4XC. I managed to glue the two halves together, and am now using that knob for the GAIN control (much less torque). It looks pretty good, but I know it is still there.   You might want to search past posts; I believe someone did have a source.

Re: [drakelist] TR-4 Problems

Hello Vance,   I remember that the OA2 tube is a voltage regulator tube. Perhaps power supply voltages would be the first thing to look at.   If you are looking for someone professional to repair it, the following web page should be helpful. (This site should be helpful to writers of other recent p

Hello all,   This morning the on/off/mode knob of my T4XC broke in two halves. I have sent a mail to Caltronix in the hope they can supply. Just in case they dont, has anyone a few (one replacement and two spare..) for me?   Best 73, Dick/PA2DW
