If you build Bernie and my FS-4B hardware (with

Re: Large amount of Drake gear in latest Schulman web auction
Sometimes you get lucky. :) They can't possibly know everything about every radio. I clued them in last year about the RX antenna loop/jumper in the TR7. They seem to be very honest and straightforward in the testing that they do. Everything I have heard about Schulman is very good. 73 -Jim NU0C On Sat, 27 Mar 2021 00:17:34 -0700 "Harold Rosee" <W5zzt1@...> wrote: I got a nice Drake 2C on the last auction.?

Re: Drake Transmitting Convertors
OK Gary - now you're just embarrassing me!? ;-)
Yes, I WILL build one of these as I need the experience in that
area.? The trouble will be getting time to do it.? I've even been
giving up a lot of skiing this winter to finish house renovations.?
Almost done.....and THIS summer will be dedicated to Ham Radio
projects for the 1st time in 3 years.? I need to finish a 2nd shack
next where the 5m dish is going, run a lot of u/g coax lines through
conduit, build a mount for the dish (10' tower has been there for
almost 3 years), and completely re-arrange the main shack which is
becoming exclusively the vintage shack.? Things got sidetracked
2-1/2 years ago while pouring the concrete bases for the two
towers.? Just as we were finishing up the 2nd pour, the ground caved
in next to one of the towers and I fell in, slamming my hand on the
form on the way in and breaking my hand.?
Regarding the Drake transverter stability.....some of that drift
comes from the oscillator in the rx converters which provide the
injection signals at 130 Mhz (for the TC-2) and 36 Mhz (for the
TC-6) as I recall.? I should really measure how stable they are
after reasonable warm-up.? And yes, I know there are stable options
for those too.? I have a Bodnar programmable oscillator that would
do the trick.
I am looking forward to seeing what the FS-5 can do and will put one
on the list of "to-do's".

HV? filtering (ripple is way too high),? wrong value? bypass caps....... it's all easily? fixed and upgraded.?
?
On? CW,? I can? insert a 0-30 msec delay, so the L4B? relay's at least get a head start, so no hotswitching, and nothing gets? truncated.? ?On? SSB,? I added an external hb delay to the yaesu's TX? inhibit lead, so? ?again,? the? L4B? TR relay? gets a head start.
Ever seen a L4B? that has been run on 11 M? AM ?? Nothing left of the bandswitch contacts, they get so hot they lose their spring tension ( just like any ameritron? al-1500/al-1200/al-82? that has been used on any band, on? RTTY).? ?Ever measured the heat on the oem? ?L4B? tank coil on? 15m and also 10m ?? ?It gets fn hot.? No, the L4B? does not fare too well after a? 11m op gets his hands on it..and? runs it? with a 900 watt un-modulated? cxr.?
Art? Bell,? W6OBB? was telling me one night, he had to make a trip to Las Vegas,? 75 miles? away.? ?When he got back, his? ALPHA? 87? was on fire, smoke everywhere,? tank assy? completely melted, a real mess.? ?Art had been using the amp on 10m? FM.? ?His cat came along? and? fell asleep on the? footswitch.? Amp had been running 1.5 kw?

It's? 58 years? since the L4 came out, and? 60 years since it was engineered.? They did a pretty good job, all things considered.? ?It's an easy upgradeable amp, with simple mods.

Subject: [DRAKE-RADIO] Need Crystal freq. for 28.5 mhz in TR4C
I need to go find a crystal to put my TR4C on 28.5-29.0 Mhz. Since I don't have one installed does anyone know the crystal freq. required.
Thank you

Re: B-line out of storage after 30 years
Gregg,
I really haven't had time to play with the transmitter yet or the power supply.? I did buy the Harbach kit for the power supply but haven't installed it yet.? I plan on firing up the power supply standalone first to see what it does before I put the kit in.
As far as the receiver goes I just plugged it it and turned it on.? I was ready for fireworks and smoke but to my surprise it played like it was new.?
What's really nice is the guy I bought this from was a school teacher at a high school.? He used it some as their club station.? For some reason he ordered 9 sets of matched finals and included them.? They are still wrapped as they came from Drake and in the shipping box they came in.? Then there were another 3 sets in regular tube boxes.? Those may be used but I'll take them.? I am set for life with finals.

Re: Large amount of Drake gear in latest Schulman web auction
I got a nice Drake 2C on the last auction.? I got a good price and when I got it I was surprised that it had the noise blanker and crystal calibrator that was not even mentioned.? It did cost a few dollars to get it here but the UPS stor packed it perfect.??
I also won a 3CX1000a tube from him and since it was small he sent it himself priority mail.? You can't beat his service.

Re: Need Crystal freq. for 28.5 mhz in TR4C
Just picked up a TR-4C that needs some re-calibration work, but it is operational.? Made a few contacts on 40 meters with it tonight.
I wouldn't mind finding a set of 42.5 Mhz xtal for 28.0 - 28.6 and the 43.6 Mhz xtal for 29.1-29.7 Mhz.? May as well get the optional crystals.
It did come with the Noise Filter.

Seen on eBay, a rare bird. Magnum Six RF speech processor, looks to be for the TR-4 series. Seller has no clue.

Re: Large amount of Drake gear in latest Schulman web auction
What you are missing is visibility. Schulman has at least a nationwide audience and his listings are detailed. Plus they do basic operational checks on all the gear and will answer questions, so you don't have the most of the issues that you do with unknown eBay sellers. 73 -Jim NU0C On Fri, 26 Mar 2021 17:44:55 -0600 "Myron Babcock" <kl7yy.radio@...> wrote: So I guess you still have to pack and ship the radio's to Dave so he can

This must be a last resort way of unloading years of boat anchor radio
equipment. Wouldn't think you would get as many dollars from the auction
process as you would through individual local or ham website sources. What
kind of fees are charging using the Schulman Auction?

Re: Large amount of Drake gear in latest Schulman web auction
You might be surprised. At least in my area hams won't pay very much for used gear. Schulman's auctions bring respectable prices. 73 -Jim NU0C On Fri, 26 Mar 2021 13:17:55 -0600 "Myron Babcock" <kl7yy.radio@...> wrote: This must be a last resort way of unloading years of boat anchor radio

Re: WA8AJS, Jeff's Mod for TR7 to Lower Power Output
It seems technically sound but IMO it is a solution in search of a problem. For decades hams have just reduced output by turning the mic gain down and it works fine. A separate power level control can encourage overdriving of the low level stages if you are not careful with your settings. I considered it and chose to not. 73 -Jim NU0C On Fri, 26 Mar 2021 08:31:10 -0700 "ko4bg" <ko4bg1@...> wrote: Has Anyone ever tried this Mod and How well does it work?
