Hi Robin

So it was you that beat me to that GPSDO - the rack mounted one?

Congratulations! I'm sure it will be OK  it looked in quite good condition. I'm pleased it went to another amateur who will use it, not a dealer that'll flog it on eBay for twice the purchace price.

My "wins" arrive today, so they will be smuggled into the garage and discretely unwrapped and tested.

73 and good luck with all your other kit.

Thanks Paul, I now have the correct type number.

I had a quick look through the Microchip line. I _think_ the bag has the wrong product in it. You might want to check that all the chips are the same (they may be a mix of 5 and 6 pin?)

try looking at: https://ww1.microchip.com/downloads/en/DeviceDoc/21350E.pdf

for the TC1054. It has the C4nn (3V3) designation and is 5 pin. The missing pin omits an additional noise reduction cap compared to the TC1072.

Wire one up and give it a try!


Re: Regulator information requested

Michael Scott
 

Hi Paul

Many thanks for the information, yes they were the 50mA version. I am very sorry I couldn't remember where they came from, my memory tends to fail me these days!!

I hope you are keeping well, and a Happy Christmas and New Year.

73, Mike.

Hello Mike
I just had a look at the reel they came from and it had the "Manufacturers Part Number" which leads to http://ww1.microchip.com/downloads/en/DeviceDoc/21335e.pdf
If I recall rightly the ones I sent you are the 50mA flavour.

Hope that helps

Hi All

The chipbank has quite a large number of 3.3 volt regulators in 5 pin
SOT23 size cases which were donated to the Chipbank, and I must
appologize to the donor as I can't remember who it was!

The bag is marked Microchip TC1072/3v3CT713, 3v3 50mA SOT23-5 LDO.

The problem is that the datasheet for the TC1072 says it is a 6 pin
device not 5 pin. The code on the device is C4MA.

Does anyone have any information?

73, Mike, G3LYP

Re: Dish for 122GHz?

Terry_G0EZY
 

Hi Neil

Many thanks for detailed reply - very pleased to see you have already been working on those reflectors and they look useful.

I have to admit I've put my 122 GHz Tx/Rx on the shelf waiting for a suitable antenna system - suitable = something easy enough for me to cope with. Looks like the arrangements you are working on could be the answer. Please could you put me down for one of these once you've finalised the design? I'm quite happy to wait at the back of the queue, as I'll be waiting until Finningley is open before starting. Hopefully, by then Kev will have his sytem running so tests across the fields will be possible.

Did you ever have any success with the SSPA boards one for 13cm that you were looking at, It was back in 2019 Martlesham.

For Sale Kuhne MKU23 G2 - 144 to 2320 Transverter

g4cch_1
 
Edited

This is this the last of my Kuhne equipment, and I built it myself from a kit, so a bit sad to see it go, but needs must.

Before anyone asks, I am not giving up, just recycling some equipment to free up cash to improve my EME system.

As stated, I built this transverter from a kit.
144 to 2320 MHz

It has only ever been used indoors as part of my EME system, and to drive an SSPA through a 20dB pad.

It has been modified to provide an external LO input - see pictures
The onboard LO is currently disabled, but this can be easily reversed.
Otherwise it is fully functional as built.

You can see pictures of it here:
