Hi Gang:
As part of my "divestiture" I am offering up for sale my BC-342 receiver made by
Farnsworth of Fort Wayne IN. This radio includes the rectifier AC power supply.
It appears to be complete and original but it is untested. The case needs to
be repainted but otherwise it is cosmetically excellent including the nametag.
Includes original TM manual.
It is heavy and I do not want to ship it. I will deliver to Deerfield/NEAR-Fest
this coming weekend. Asking price is $150.00. If interested please reply by
e-mail.
73,
Michael, W1RC

Hi,
Just put this up and was wondering about the length of the radials for the ground plane. It is up about 15 feet and will be used with my PRC-70, hence the frequency range.
Thanks,

Did anyone tune the TCS by the chart in the first place? Maybe you used the chart for starting settings and then tuned the transmitter for max antenna current but if you just used the charts and ignored the antenna current meter and the plate current meter why did they install them in the first place?
The question I would have is was the radio set up by a technician on the crystals that were installed with the readings written down on the front cards and the crews of the boats were told to set the radio up according to the chart that way or were users of the radio instructed on how to tune the transmitter? Or perhaps back at the dock a tech set the radio on one channel and everyone was told just use that set up channel and don't touch the radio?
I know it antidotal at best but both of the great grandsons of the TCS the Sunair GSB-800 and the Harris URC-94 have huge stickers on top of the radios that have the operating instructions written for idiots but they do tell you how to change the frequency and tune the antenna.
In the old days of HF AM marine radio all the transceivers they had for small boats had no provision for any transmitter adjustments for the user, the loading coils and everything was installed in the radio with no user access. My understanding then was that you had to have at least a second class license to set up or tune one of those old HF AM transceivers.

The TCS "Typical Dial Readings" chart is a very valuable aid when tuning
SHORT antennas, even to the experienced operator. As you well know with
your amateur experience matching a single antenna on different bands- -
- when you have tuned or matched your "antenna system" for maximum
current (conjugate match) there are sometimes two or sometimes three
settings that will produce a good output but it helps to be in the ball
park for the correct setting, This "correct setting" gives maximum
output, best efficiency, less heating of matching components as well
as provide maximum harmonic retention.
BTW the TCS does not have any capability to spot or monitor the transmit
crystal. I will post a "spot" mod on my web page in the near future.
Yes, it did require a FCC license.

Never knew there was a chart but don't think I ever saw the manual for the TCS anyway, have seen the schematic and the stuff in the CQ surplus conversion manuals and have operated the transmitters and receivers on occasion although don't have any today. My policy was to always tune to max current on antenna meter and dip for minimum current on plate. Other question would be the external antenna loading coil, I have always found the original coil to be just about useless on every antenna that I have connected the radio too. maybe on a short loaded vertical but with any long wire that coil did nothing but work in bypass. Other than that the TCS appears to be a good little radio although somewhat under powered for AM use. Would assume the TCS was the floating equal of the ARC-5 in terms of being a good radio for short range communications but not intended for anything beyond that?
