Re: PRC320 and dipole?

 

Ben.

As we (I) said earlier this was an amateurs bodge, not official teaching

In reality the 320 does tolerate a substantial mismatch, although there is no way of know what the output is under such circumstances, in service terms.

It automatically turns down the output to carry a mismatch

Re: PRC320 and dipole?

 

Hi Ben,

No problems feeding the dipole directly, bypassing the internal tuner, I have a dipole cut exactly for 80m (3729Khz) and get good reports when I check on a daily net.? One just have to make sure the dipole is cut to the frequency and present a 50 ohm load to the PRC320 transmitter.? ( I use an antenna analyzer to check the antenna beforehand).
Have fun

These 4000mA ones were from Lidl, they had an offer on for AAA, AA, C and D of which I bought quite a few. I think my AAA and AA are ok, the D's I have used in various sets but only a couple of charges and these C cells I put into a Racal battery box as getting the D's in without tags etc?is near impossible.

Still, they were cheap so that has to tell you something !

It's fun creative writing! Get another gmail account like Phil.Dirt@... and practice your creativity. It's a hoot to collect their phony-assed checks, and then read their pidgin-english death threats after informing them that you've spent 'their money' on hookers and drugs!

FW: Clark mast for sale

 

Dear All

I have a Clark 15M light duty mast surplus to requirements and would like
to offer it to you before resorting to e-Bay.

The mast is a "Surveyor 15M" I bought from Telford Electronics at the
Picketts Lock rally in the mid 1990s and is 15M tall when extended, 3.5M
tall retracted and has a 4.5 inch base tube with a 25mm antenna socket at
the top. The main tube weighs about 110lb and the legs must be almost as
much again. I believe the Surveyor is closely related to the Clark PT mast
series although the clamps are more like a SCAM40.

The mast was last fully extended in February 2010 after I replaced a stuck
locking collar - it probably could do with some refurbishment because it
does not stay up long without the locking collars, but is still easily
pumped up with a car compressor.

Please have a look at:

Unfortunately I then tried to remove the air in socket to clean off the
rust and found that I had stripped the thread - so it will need drilling
out and a (13mm?) Hellicoil inserting. You can buy replacement air in
socket and hose on e-bay for ?15 - see item 170530328596. It is also
possible to hand-extend it with light head loads.

Since I now have other masts that are stronger and short enough to fit my
car I and have limited time to work on it I am offering this for one for
sale as-is for refurbishment, spares or repair and would be interested in
offers over ?250.

Please contact me on 07850 424 007 or at g0ozs@... to arrange
viewing or to make an offer ! I would prefer to have it out of the way by
the end of the month so will accept the best offer over ?250 (which I am
sure I can get on e-bay) received by 30th September 2010.

The mast is too heavy to take down safely single handed and I do not have a
car with a roof rack now, so it is strictly buyer to inspect and collect.
Because of the need to dismantle I think courier collection is impractical.
I am located between Ipswich and Colchester in East Anglia about 3 miles
from the A12 and 5 miles from the A14.

Regards

Iain

Possible scam warning

 

Hi, All,

I'm now receiving a message similar to the following at least once a day. All attempts to contact the sender have resulted in no response, and I suspect it may be a prelude to an attempted scam. All emails are identical with the exception of, in the example below, the word "Manuals", but this always has an additional leading space character, the "i am located" always has a lower-case "i", there is always a missing space character before "Do", and the item advertised is always referred to as "he".

The information has also been passed to Gmail but has so far not produced any response.

If Ms.Wilson has a legitimate reason for making these postings I apologise, and I'm sure we would all love to hear it.

regards,

Bob

MA4010 High speed morse units on eBay

 

If anyone is thinking about making an offer on the rather over priced units going round on ebay, be aware that the Audio connectors are not the standard ones but the 8 pin French (?) kind, so the usual handsets and keys cannot be used. I had a similar unit and converted it back to the standard connectors but it was mechanically really hard to do and not a task I would wish on anyone. I think I paid more for the two connectors than I paid for the whole unit.

Clever design though.

For Sale: Military Communications 1988/89

 

Hi, All,

I've decided to sell my copy of the Interavia Data publication "Military Comms 1988/89". For those of you who haven't come across it, this is the military comms industry standard reference book, printed in two volumes with a total of 1900 pages, and taking up 120mm of bookshelf space!

Unlike Jane's, this publication has no illustrations, but has more comprehensive detail about purchasers/users of each individual equipment item. It is also cross-referenced in a number of ways including by User, so that it is possible, for instance, to see which equipment might have been contemporary with a vehicle in a particular country's service. The description of each item is similar to entries in Janes.

?35 - I could consider posting but it is obviously fairly heavy. I'm located in Worcestershire.

regards,

Bob
