- Glass bottles work quite well as insulators for vertical antennas - until

-
- Wine bottles work better than beer bottles because the area around the

- bottle to see if that made a difference.
-
- One other thing - I learned the hard way that a vertical made this way
- without a DC path to ground will transmit like gangbusters, but the
- corona noise on receive will make your radio essentially useless for
- about 10 seconds out of every minute. It sounds like a motor starting up
- at about 3/4 speed for 6 seconds (and about S-6) then 4 seconds at full
- speed (and S-9+30 dB) then it goes away and the receiver recovers.

- I have no experience with this radio myself but can give you some
- second hand information from a mail list discussion:
-
- This is a fairly early HF all solid-state radio. Probably built in
- mid to late 1970's.
-
- Drake equipment is generally quite good and all the comments on this
- unit were favorable. It was built before synthesizers, so it is all
- analog.
-
- The radio tunes in 500kHz segments and needs a crystal for each segment.
- You should ask what crystals the unit has. There was also an outboard
- accessory available that replaced the crystals and allowed tuning
- all segments.
-
- It should tune up to 30MHz if you have the right crystals for it.
-
- I am not sure exactly what kind of filtering it used; ask about
- filters that it has. It is important to have the right filter
- for the type of signal you want to receive.
-
- Prices mentioned were in the US$200 - US$300 range.

-
- Hello,
-
- Having just gone through the process for the UK I can give you some advice.
-
- There are two types of temporary license, a two month one where no fixed
- address is given, i.e. mobile during a holiday (US translation: Vacation Trip)
- and a twelve month one where a main station address is supplied, i.e. long
- stay. Neither license is renewable and no UK call is assigned.
- If you are a US ham then you need a Conditional/General License or above.
-
- A few years ago I would have suggested getting the forms from the ARRL. I
- appeciated the service so I joined ARRL for a few years. However this year I
- rang up and was told after the person found out that I was not an ARRL member
- that providing the forms is "a ARRL Member Service and members get upset if
- non-members get it for free". I was allowed to send a SASE to the league
- and get the information so they saved 29 cents in postage and lost a year's
- worth of dues. It is a wonder members do not complain about non-members
- accessing ARRL's info server. So if you are not a ARRL member then expect
- some flack and if the ARRL is in a good mood maybe you can send in a SASE.
- Otherwise go to the RA or RSGB.
-
- The application has the address and information you need. The main problem
- is that you need a 15 pound fee as either a British Cheque, British Postal
- Order, or International Money Order. The easiest way is if you have a friend
- in the UK to send the application to him and have him send a check with the
- remailed application. The next cheapest is to send an international money
- order. The problem is that a international money order is issued by paying
- the fee at the local post office and sending a application to Saint Louis
- where the International Money Order is issued. I have run into numerous
- problems with this method as the application and money order do not seem to
- arrive at the same time. The most expensive is to go to a bank and get a
- International Banker's Draft in Pounds Sterling.
-
- To dial the following numbers in the US: dial the international access code,
- usually 011, followed by the Country Code for the UK, 44, then the number
- given without the leading zero. So (0272) 258333 would be dialed as
- 011+44+272+258333.
-
-
- The Radiocommunications Agency regulates amateur radio in the UK, but the
- issuing of licenses is handle by a private contractor. So you send the
- application to:
-
- The Radio Licensing Centre
- SSL
- P.O. Box 884
- Bristol BS99 5LF
- England
-
- The telephone is (0272) 258333
-
- You could get the application from the RA. Here is the infomation I have:
-
- Amateur Radio Licensing Section
- Radiocommunications Agency
- Waterloo Bridge House
- Waterloo Road
- London SE1 8UA
- England
-
- The telephone is (071) 215-2217 -or- (071) 215-2316 (answerphone)

- I have traveled with a portable shortwave radio for over 10 years
- Internationally without any real problems. Infact I once lugged my ICOM
- R71A to Fiji (stupid move...I used it once in 3 weeks). Here is my advice:
- Never offer any information or explanation without being asked first.
- When asked, make your answers short and simple w/o any tech mumbo jumbo.
- Don't try to hide anything or be conspicuous (like on your belt).
- Remember, customs officals have all day to do their jobs and sometimes
- just like to excersize their authority. I have no experience in taking
- ham gear overseas so I can't help you there.

- Hello..... this would NOT BE LEGAL either, as you cannot cross Amateur radio
- with another radio service. My grandfather looked into this when he was
