Thank you Chuck. I've made the change and this email message checks it out. For my email application, "Reply" puts in the group address, "Reply All" puts in both group address and a cc: to the sender I'm replying to. One more thing accomplished.

consensus has been (on more than one list I've run) to have the reply

Re: T/R Switching

Bill Cromwell
 

Hi,

I have come to prefer separate transmitter/receiver operation. I also
prefer to listen to my transmitter instead of having just a sidetone
audio oscillator (CW). In any case when I changeover from transmit to
receive the receiver antenna terminal(s) are directly grounded. Even if
I have a separate receive antenna that is still something I do.

My "pretty" receivers are setup to completely mute everything from the
antenna up to the audio stage and audio is left on for the sidetone. I
have used receivers that don't quite silence the rf/if stages and allow
us to set the level that can come though - *almost* silenced. The
receiver oscillator and mixer are running and the amplifiers are mostly
shut down. The transmitted signal becomes the "sidetone". I am modifying
my reveivers that don't work that so that they will. When we operate
that way we will notice anything that isn't just quite right including
"forgot to net the TX". Don't ask me how I know that (evil grin).

It's possible to do all of that with full break-in QSK or semi break-in.
I have come to prefer a manual switch that changes everything over for
the T/R functions. It is the easiest to implement and the most reliable.
I have a set of Kenwood Twins that are setup with the transceive cable
and semi break-in using the VOX. On that rig I just use the manual T/R
switch on the front panel of the transmitter..same as all the rest.
Sometimes the QSK process cuts off part or even all of the first dit and
if the first element is a dah it can become a dit. The manual switch
eliminates that. The first tap of the key is already live.

Re: T/R Switching

Hi Jim,
Phil Salas, AD5X, wrote a QST article about a boat anchor T/R switch. He has a copy on his web site. It is here:
<http://www.ad5x.com/images/Articles/QSKBArevA.pdf>

One of the problems I see with his design is that he uses 2 relays. The first relay follows your keying or keyer. He uses this relay to mute the receiver and key the transmitter. A problem may occur because the relay will switch with the keyer and the relay will unmute the receiver before the transmitter signal has decayed. If you added a second relay to his design one which would be in parallel with the antenna relay, it would probably work fine. The additional relay would be used to mute the receiver. His design will handle up to 100 watts or so.

Good question.  I do a lot of fooling with different boatanchor matchups.  I built this RF sensing antenna switcher from Solid State Design for the Radio Amateur a few years ago that serves me well.  It has adjustable drop out, so it's semi-break-in.  But no provision for muting so I ride the AF & RF gains.

For little QRP RX and TX boards, I might just use an SPDT toggle switch to swap between TX and RX and maybe get those phones off my ears a bit before transmitting.

But like you said, you'd like to protect a more modern rig.  The old BAs were tough. With some kind of SPDT arrangement whether relay or toggle switch, you're never going to have the TX connected directly into the RX input.  Worst case, slow switching will have the TX deadheaded for a few ms but I don't know that you'd couple excess RF into the receiver doing that.  Maybe if you're on 80 or 40 you can afford to have the preamp off and even a bit of attenuation turned on for an extra measure of protection.  A bandaid fix for sure, I admit.  However, I have a K3 and if it senses excess RF into the receiver, it will start automatically taking such steps.

If your switch or relay had an extra pole, you could use it to ground the RX antenna input during transmit.  That still leaves you with that switching time vulnerability though.  The only thing I can think of for that is some kind of sequencer, like a microcontroller.  Or as others have said:

Something like the magic box would be the Cadillac solution, of course.

Early 80m net

Wayne Dillon
 

Ge all. For those who missed the e-mail it was my privelage to stand in for Terry on the early 80m net tonight. He is/was on his way back from Branson and would be calling the late net. As it turned out I should have volunteered to do the late net as well because when I tried '40 at the late net time it was a bust. Oh well, that's how it goes sometimes. I was rewarded with a bumper check-in on '80 though:

N0NBD - Paul - KS
K0MC - Mike - CO
K2HT - Harold - MO
K5DCM - David - AR
KB4QQJ - Randy - NC
N9RLO - John - IN
KI8R - Michael - OH
AC5P - Michael - OK

To all who checked in a huge thank you for making my evening, it was a blast. To those I missed, my apologies and I will try harder next time. Hopefully '40 will start to improve as we progress towards spring. Unless otherwise informed I'll be back on '40 next week. If I have the opportunity I may give '30 a go over the weekend. If I do I'll post to QRPSpots.

P.S. Terry, I'm beginning to see the attraction of 80m :)

Re: Balloon beacon

Tom <n2uhc@...>
 

I won't be listening for the beacon since the last time I listened out for it I couldn't hear it on any freq. I guess 20 meters doesn't work from Kansas to Iowa (even at 90K feet). Nor was I able to hear the 2m or packet signals direct after my QTH was inside the radio horizon. I'm just a little too far away, I guess.

Jim,

Hey, looking forward to seeing you. Seems like a long time since you have been to any of the 4Sqrp functions. I remember well that you sent a note to Elecraft and they sent me a Elecraft tee because I was using my K1 to demo the KD1JV swr/pwr meter the group was selling as a kit. Also remember you showing up down at Twin Bridges with a newly built K2. Not sure if that was FD or just a qrp weekend get together. I think it was that same get together that you put a quick fix on my little 30 meter monobander!

Anyway, It will be good to see you at Ocon. I will have my K2 using it for K0N special events station and the "in hotel" dummy load test!!

Wednesday nite nets Please not NCS Changes for this week only

Wayne Dillon
 

Changes for this week only:
I will be calling the 01:00z 80m net while Terry journey's back from Branson and will continue with it until 02:00z, Terry should be back by then, If we get through with the 80m net by 01:30z then I will QSY to 40 (7.122 or thereabouts, keep an eye on QRP Spots). If we're going on past 01:30 then I will QSY to '40 whan '80 is played out. Nevertheless  I will be on '40 at 02:30z

The Four State QRP Comfortable nets meet each Wednesday night
beginning at 7:00 PM CST, 0100z. It's gonna be a great night to
stay in, stay warm, and play radio.  Tonight let's exchange our
4SQRP numbers.

If we have to QSY, I like to move up, Wayne likes to move down,
and Dick doesn't have to move much at all.

Add anything to the exchange that you wish, temp rig, ant, etc.
Checking into both, or even all, sessions is encouraged.
Who will be the first to check into all of them?

7:00 CST 0100z ... 80M CW Net on 3564,  KC0PMH NCS.
7:30 CST 0130z ... 40M CW Net on 7122,  KCØPMH NCS
8:00 CST 0200z ... 80M CW Net on 3564,  WAØITP NCS.
8:30 CST 0230z ... 40M CW Net on 7122,  KCØPMH NCS
9:00 CST 0300z ... 80M PSK Net on 3580.5,  NØTGR NCS

All are welcome!  After the nets, a list of checkins will be
posted on the Four State reflector.

Re: T/R Switching

Wayne Dillon
 

Hi Jim,
One of the solutions which springs to mind is the "Magic Box" an excellent example of one of the 4SQRP kits, check it out on the website. One other solution I have used in the past is a single transistor driven C/O driving a relay, don't forget to put a couple of back-to-back diodes across the RX input to help limit what the RX sees. I can't guarantee it's safety with the good ole '857 though. There will be others on here who will no doubt offer more accurate and up-to date advice. Do ckeck out the "Magic Box" though, as a standalone solution to T/R switching it's neat.
