Builder's Corner / Makeshift Square Loop Antenna for a Crystal Radio
« Last post by vu2nan on November 08, 2019, 04:12:16 UTC »
A heavy 2 m x 2 m floor-standing wooden showcase in the shack appeared to be suitable as a frame for a crystal radio loop antenna. As luck would have it, the lone 20 km distant 612 kHz, 200 kW AM broadcast station being in the end-on position by default, there would be no need to move the unit. The counter top would make it quite convenient to sit down and carry out the testing.

The 5 turn loop was easily wound using about 42 m of ordinary hook-up wire.

The shack is relatively quite small to get a photo of the actual unit.

Here's a representation of the same.

It works quite well with my series/parallel-tuned crystal radios.

Transceivers / Pictures needed inside TS-120V
« Last post by PA1CJT on November 07, 2019, 12:23:31 UTC »
Hi all, I have obtained an TS-120V did not receive, missed display (only dots) and no TX (not on SSB and not on CW. Searching the internet for causes and solutions and found some. So it is receiving again and it has digital dispaly working but still no TX.
When pushing the PTT or TX handle both the relays are activated but no signal. I placed a counter between the radio and the dummyload but no frequency displayed.

First I need to check if all cabling and connectors are properly and correct in place therefore I would have the pictures. I have already a spare set of capacitors for replacement.

First inspection shows no damaged resistors or blown capacitors.

I would love to bring this radio back alive but my repair skills are not that good.

I hope someone will read this and can support me with the pictures or advice.

Hi OM Kees,

I guess we have a lot in common, sharing the same ideas and sentiments!

Many thanks.

Hello Nandu,

how simple it can be! Like going back to my childhood building with a minimum of components a simple receiver. People will be surprised hearing a radio station with a unpowered 'thing' with a connected wire and headphone....

As earlier mentioned just a few post have been made lately or has been read. As written in another post there is enough development going on in the world of QRP so it will still sell. Perhaps new items must be add to get people curious about QRP (again).

Is it the QRP Club or more QRP which is dead? As far I can see QRP transceivers are still in development, build and sold of fabric. So what could be the reason that HAM's stay away from QRP Club?
QRP / Index Laboratories Companion
« Last post by PA1CJT on November 02, 2019, 12:01:03 UTC »
Well I do have a QRP Plus (serial 1078) and would like to have a complete station. I noticed that there are just a few Companions around so I guess that I have to build one of my own. But......the manual I have has a schema but no PCB layout or foto's how it is build. The request I have is if someone within the QRP Club who has a Companion is willing to make pictures from the inside to give me the idea whou it is build up.
I think only to build te LC tuner and really have to think about the filter and battery loading.

If there is someone which experiences of the Companion plse react as well
